copy - paste in javascript - javascript

I have this code
<input name="mpan[]" value="" maxlength="2" size="2">
<input name="mpan[]" value="" maxlength="2" size="3">
<input name="mpan[]" value="" maxlength="2" size="3">
<input name="mpan[]" value="" maxlength="2" size="12">
What I have to do is I am provided with a large key for example 0380112129021. When I do Ctrl+C on that key and select any box and press Ctrl+V, the number automatically get pasted in different box, for example: first input box gets 03, next gets 801, next gets 112 and rest gets pasted on last one 129021.how do i achive this from javascript

If you're looking to catch paste events (rather than the literal Ctrl+V), the onpaste event may be for you, and is supported by most browsers according to this answer.
The splitting of the input value you could do using substring().

Easy. On each of the input box, add an onkeyup handler and inspect the input values.
Little clarification, you're trying to do something like serial/key input boxes, right?

okay if you have no idea you should read through some stuff.
i can recommend to read about
javascript - events.
especialy the onkeyup/onkeydown events
stringparsing (substring)
after that you will see the answer glowing on your screen ;-)
a little hint: if you store the pressed keys to a variable, it should be cleared after the action is triggered. and you should check what you have in you keypress cache and clear illigal input.

Disable 'Recently Entered Values' Dropdown For <input> Fields [duplicate]

This question's answers are a community effort. Edit existing answers to improve this post. It is not currently accepting new answers or interactions.
I have been running into issues with the chrome autofill behavior on several forms.
The fields in the form all have very common and accurate names, such as "email", "name", or "password", and they also have autocomplete="off" set.
The autocomplete flag has successfully disabled the autocomplete behavior, where a dropdown of values appear as you start typing, but has not changed the values that Chrome auto-populates the fields as.
This behavior would be ok except that chrome is filling the inputs incorrectly, for example filling the phone input with an email address. Customers have complained about this, so it's verified to be happening in multiple cases, and not as some some sort of result to something that I've done locally on my machine.
The only current solution I can think of is to dynamically generate custom input names and then extract the values on the backend, but this seems like a pretty hacky way around this issue. Are there any tags or quirks that change the autofill behavior that could be used to fix this?
Apr 2022: autocomplete="off" still does not work in Chrome, and I don't believe it ever has after looking through the Chromium bugs related to the issue (maybe only for password fields). I see issues reported in 2014 that were closed as "WontFix", and issues still open and under discussion [1][2]. From what I gather the Chromium team doesn't believe there is a valid use case for autocomplete="off".
Overall, I still believe that neither of the extreme strategies ("always honor autocomplete=off" and "never honor autocomplete=off") are good.

They are under the impression that websites won't use this correctly and have decided not to apply it, suggesting the following advice:
In cases where you want to disable autofill, our suggestion is to
utilize the autocomplete attribute to give semantic meaning to your
fields. If we encounter an autocomplete attribute that we don't
recognize, we won't try and fill it.
As an example, if you have an address input field in your CRM tool
that you don't want Chrome to Autofill, you can give it semantic
meaning that makes sense relative to what you're asking for: e.g.
autocomplete="new-user-street-address". If Chrome encounters that, it
won't try and autofill the field.
https://bugs.chromium.org/p/chromium/issues/detail?id=587466#c10
Although this "suggestion" currently works for me it may not always hold true and it looks like the team is running experiments, meaning the autocomplete functionality could change in new releases.
It's silly that we have to resort to this, but the only sure way is to try and confuse the browser as much as possible:
Name your inputs without leaking any information to the browser, i.e. id="field1" instead of id="country".
Set autocomplete="do-not-autofill", basically use any value that won't let the browser recognize it as an autofillable field.
Jan 2021: autocomplete="off" does work as expected now (tested on Chrome 88 macOS).
For this to work be sure to have your input tag within a Form tag
Sept 2020: autocomplete="chrome-off" disables Chrome autofill.
Original answer, 2015:
For new Chrome versions you can just put autocomplete="new-password" in your password field and that's it. I've checked it, works fine.
Got that tip from Chrome developer in this discussion:
https://bugs.chromium.org/p/chromium/issues/detail?id=370363#c7
P.S. Note that Chrome will attempt to infer autofill behavior from name, id and any text content it can get surrounding the field including labels and arbitrary text nodes. If there is a autocomplete token like street-address in context, Chrome will autofill that as such. The heuristic can be quite confusing as it sometimes only trigger if there are additional fields in the form, or not if there are too few fields in the form. Also note that autocomplete="no" will appear to work but autocomplete="off" will not for historical reasons. autocomplete="no" is you telling the browser that this field should be auto completed as a field called "no". If you generate unique random autocomplete names you disable auto complete.
If your users have visited bad forms their autofill information may be corrupt. Having them manually go in and fix their autofill information in Chrome may be a necessary action from them to take.
I've just found that if you have a remembered username and password for a site, the current version of Chrome will autofill your username/email address into the field before any type=password field. It does not care what the field is called - just assumes the field before password is going to be your username.
Old Solution
Just use <form autocomplete="off"> and it prevents the password prefilling as well as any kind of heuristic filling of fields based on assumptions a browser may make (which are often wrong). As opposed to using <input autocomplete="off"> which seems to be pretty much ignored by the password autofill (in Chrome that is, Firefox does obey it).
Updated Solution
Chrome now ignores <form autocomplete="off">. Therefore my original workaround (which I had deleted) is now all the rage.
Simply create a couple of fields and make them hidden with "display:none". Example:
<!-- fake fields are a workaround for chrome autofill getting the wrong fields -->
<input style="display: none" type="text" name="fakeusernameremembered" />
<input style="display: none" type="password" name="fakepasswordremembered" />
Then put your real fields underneath.
Remember to add the comment or other people on your team will wonder what you are doing!
Update March 2016
Just tested with latest Chrome - all good. This is a fairly old answer now but I want to just mention that our team has been using it for years now on dozens of projects. It still works great despite a few comments below. There are no problems with accessibility because the fields are display:none meaning they don't get focus. As I mentioned you need to put them before your real fields.
If you are using javascript to modify your form, there is an extra trick you will need. Show the fake fields while you are manipulating the form and then hide them again a millisecond later.
Example code using jQuery (assuming you give your fake fields a class):
$(".fake-autofill-fields").show();
// some DOM manipulation/ajax here
window.setTimeout(function () {
$(".fake-autofill-fields").hide();
}, 1);
Update July 2018
My solution no longer works so well since Chrome's anti-usability experts have been hard at work. But they've thrown us a bone in the form of:
<input type="password" name="whatever" autocomplete="new-password" />
This works and mostly solves the problem.
However, it does not work when you don't have a password field but only an email address. That can also be difficult to get it to stop going yellow and prefilling. The fake fields solution can be used to fix this.
In fact you sometimes need to drop in two lots of fake fields, and try them in different places. For example, I already had fake fields at the beginning of my form, but Chrome recently started prefilling my 'Email' field again - so then I doubled down and put in more fake fields just before the 'Email' field, and that fixed it. Removing either the first or second lot of the fields reverts to incorrect overzealous autofill.
Update Mar 2020
It is not clear if and when this solution still works. It appears to still work sometimes but not all the time.
In the comments below you will find a few hints. One just added by #anilyeni may be worth some more investigation:
As I noticed, autocomplete="off" works on Chrome 80, if there are fewer than three elements in <form>. I don't know what is the logic or where the related documentation about it.
Also this one from #dubrox may be relevant, although I have not tested it:
thanks a lot for the trick, but please update the answer, as display:none; doesn't work anymore, but position: fixed;top:-100px;left:-100px; width:5px; does :)
Update APRIL 2020
Special value for chrome for this attribute is doing the job: (tested on input - but not by me)
autocomplete="chrome-off"
After months and months of struggle, I have found that the solution is a lot simpler than you could imagine:
Instead of autocomplete="off" use autocomplete="false" ;)
As simple as that, and it works like a charm in Google Chrome as well!
August 2019 update (credit to #JonEdiger in comments)
Note: lots of info online says the browsers now treat autocomplete='false' to be the same as autocomplete='off'. At least as of right this minute, it is preventing autocomplete for those three browsers.
Set it at form level and then for the inputs you want it off, set to some non-valid value like 'none':
<form autocomplete="off">
<input type="text" id="lastName" autocomplete="none"/>
<input type="text" id="firstName" autocomplete="none"/>
</form>
Sometimes even autocomplete=off won't prevent filling in credentials into wrong fields.
A workaround is to disable browser autofill using readonly-mode and set writable on focus:
<input type="password" readonly onfocus="this.removeAttribute('readonly');"/>
The focus event occurs at mouse clicks and tabbing through fields.
Update:
Mobile Safari sets cursor in the field, but does not show virtual keyboard. This new workaround works like before, but handles virtual keyboard:
<input id="email" readonly type="email" onfocus="if (this.hasAttribute('readonly')) {
this.removeAttribute('readonly');
// fix for mobile safari to show virtual keyboard
this.blur(); this.focus(); }" />

Explanation: Browser auto fills credentials to wrong text field?
filling the inputs incorrectly, for example filling the phone input with an email address
Sometimes I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess, the browser looks for a password field to insert your saved credentials. Then it autofills username into the nearest textlike-input field , that appears prior the password field in DOM (just guessing due to observation). As the browser is the last instance and you can not control it,
This readonly-fix above worked for me.
If you are implementing a search box feature, try setting the type attribute to search as follows:
<input type="search" autocomplete="off" />
This is working for me on Chrome v48 and appears to be legitimate markup:
https://www.w3.org/wiki/HTML/Elements/input/search
I don't know why, but this helped and worked for me.
<input type="password" name="pwd" autocomplete="new-password">
I have no idea why, but autocomplete="new-password" disables autofill. It worked in latest 49.0.2623.112 chrome version.
Try this. I know the question is somewhat old, but this is a different approach for the problem.
I also noticed the issue comes just above the password field.
I tried both the methods like
<form autocomplete="off"> and <input autocomplete="off"> but none of them worked for me.
So I fixed it using the snippet below - just added another text field just above the password type field and made it display:none.
Something like this:
<input type="text" name="prevent_autofill" id="prevent_autofill" value="" style="display:none;" />
<input type="password" name="password_fake" id="password_fake" value="" style="display:none;" />
<input type="password" name="password" id="password" value="" />
Hope it will help someone.
For me, simple
<form autocomplete="off" role="presentation">
Did it.
Tested on multiple versions, last try was on 56.0.2924.87
You have to add this attribute :
autocomplete="new-password"
Source Link : Full Article
It is so simple and tricky :)
google chrome basically search for every first visible password element inside the <form>, <body> and <iframe> tags to enable auto refill for them, so to disable this you need to add a dummy password element as the following:
if your password element inside a <form> tag you need to put the dummy element as the first element in your form immediately after <form> open tag
if your password element not inside a <form> tag put the dummy element as the first element in your html page immediately after <body> open tag
You need to hide the dummy element without using css display:none so basically use the following as a dummy password element.
<input type="password" style="width: 0;height: 0; visibility: hidden;position:absolute;left:0;top:0;"/>
Here are my proposed solutions, since Google are insisting on overriding every work-around that people seem to make.
Option 1 - select all text on click
Set the values of the inputs to an example for your user (e.g. your#email.com), or the label of the field (e.g. Email) and add a class called focus-select to your inputs:
<input type="text" name="email" class="focus-select" value="your#email.com">
<input type="password" name="password" class="focus-select" value="password">
And here's the jQuery:
$(document).on('click', '.focus-select', function(){
$(this).select();
});
I really can't see Chrome ever messing with values. That'd be crazy. So hopefully this is a safe solution.
Option 2 - set the email value to a space, then delete it
Assuming you have two inputs, such as email and password, set the value of the email field to " " (a space) and add the attribute/value autocomplete="off", then clear this with JavaScript. You can leave the password value empty.
If the user doesn't have JavaScript for some reason, ensure you trim their input server-side (you probably should be anyway), in case they don't delete the space.
Here's the jQuery:
$(document).ready(function() {
setTimeout(function(){
$('[autocomplete=off]').val('');
}, 15);
});
I set a timeout to 15 because 5 seemed to work occasionally in my tests, so trebling this number seems like a safe bet.
Failing to set the initial value to a space results in Chrome leaving the input as yellow, as if it has auto-filled it.
Option 3 - hidden inputs
Put this at the beginning of the form:
<!-- Avoid Chrome autofill -->
<input name="email" class="hide">
CSS:
.hide{ display:none; }
Ensure you keep the HTML note so that your other developers don't delete it! Also ensure the name of the hidden input is relevant.
Use css text-security: disc without using type=password.
html
<input type='text' name='user' autocomplete='off' />
<input type='text' name='pass' autocomplete='off' class='secure' />
or
<form autocomplete='off'>
<input type='text' name='user' />
<input type='text' name='pass' class='secure' />
</form>
css
input.secure {
text-security: disc;
-webkit-text-security: disc;
}
Previously entered values cached by chrome is displayed as dropdown select list.This can be disabled by autocomplete=off , explicitly saved address in advanced settings of chrome gives autofill popup when an address field gets focus.This can be disabled by autocomplete="false".But it will allow chrome to display cached values in dropdown.
On an input html field following will switch off both.
Role="presentation" & autocomplete="off"
While selecting input fields for address autofill Chrome ignores those input fields which don't have preceding label html element.
To ensure chrome parser ignores an input field for autofill address popup a hidden button or image control can be added between label and textbox. This will break chrome parsing sequence of label -input pair creation for autofill.
Checkboxes are ignored while parsing for address fields
Chrome also considers "for" attribute on label element. It can be used to break parsing sequence of chrome.
In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:
autocomplete="nope"
I've found that adding this to a form prevents Chrome from using Autofill.
<div style="display: none;">
<input type="text" id="PreventChromeAutocomplete" name="PreventChromeAutocomplete" autocomplete="address-level4" />
</div>
Found here. https://code.google.com/p/chromium/issues/detail?id=468153#hc41
Really disappointing that Chrome has decided that it knows better than the developer about when to Autocomplete. Has a real Microsoft feel to it.
<input readonly onfocus="this.removeAttribute('readonly');" type="text">
adding readonly attribute to the tag along with the onfocus event removing it fixes the issue
In 2016 Google Chrome started ignoring autocomplete=off though it is in W3C. The answer they posted:
The tricky part here is that somewhere along the journey of the web autocomplete=off become a default for many form fields, without any real thought being given as to whether or not that was good for users. This doesn't mean there aren't very valid cases where you don't want the browser autofilling data (e.g. on CRM systems), but by and large, we see those as the minority cases. And as a result, we started ignoring autocomplete=off for Chrome Autofill data.
Which essentially says: we know better what a user wants.
They opened another bug to post valid use cases when autocomplete=off is required
I haven't seen issues connected with autocomplete throught all my B2B application but only with input of a password type.
Autofill steps in if there's any password field on the screen even a hidden one.
To break this logic you can put each password field into it's own form if it doesn't break your own page logic.
<input type=name >
<form>
<input type=password >
</form>
For username password combos this is an easy issue to resolve. Chrome heuristics looks for the pattern:
<input type="text">
followed by:
<input type="password">
Simply break this process by invalidating this:
<input type="text">
<input type="text" onfocus="this.type='password'">
Mike Nelsons provided solution did not work for me in Chrome 50.0.2661.102 m.
Simply adding an input element of the same type with display:none set no longer disables the native browser auto-complete. It is now necessary to duplicate the name attribute of the input field you wish to disable auto-complete on.
Also, to avoid having the input field duplicated when they are within a form element you should place a disabled on the element which is not displayed. This will prevent that element from being submitted as part of the form action.
<input name="dpart" disabled="disabled" type="password" style="display:none;">
<input name="dpart" type="password">
<input type="submit">
There's two pieces to this. Chrome and other browsers will remember previously entered values for field names, and provide an autocomplete list to the user based on that (notably, password type inputs are never remembered in this way, for fairly obvious reasons). You can add autocomplete="off" to prevent this on things like your email field.
However, you then have password fillers. Most browsers have their own built-in implementations and there's also many third-party utilities that provide this functionality. This, you can't stop. This is the user making their own choice to save this information to be automatically filled in later, and is completely outside the scope and sphere of influence of your application.
If you're having issues with keeping placeholders but disabling the chrome autofill I found this workaround.
Problem
HTML
<div class="form">
<input type="text" placeholder="name"><br>
<input type="text" placeholder="email"><br>
<input type="text" placeholder="street"><br>
</div>
http://jsfiddle.net/xmbvwfs6/1/
The above example still produces the autofill problem, but if you use the required="required" and some CSS you can replicate the placeholders and Chrome won't pick up the tags.
Solution
HTML
<div class="form">
<input type="text" required="required">
<label>Name</label>
<br>
<input type="text" required="required">
<label>Email</label>
<br>
<input type="text" required="required">
<label>Street</label>
<br>
</div>
CSS
input {
margin-bottom: 10px;
width: 200px;
height: 20px;
padding: 0 10px;
font-size: 14px;
}
input + label {
position: relative;
left: -216px;
color: #999;
font-size: 14px;
}
input:invalid + label {
display: inline-block;
}
input:valid + label {
display: none;
}

I really did not like making hidden fields, I think that making it like that will get really confusing really fast.
On the input fields that you want to stop from auto complete this will work. Make the fields read only and on focus remove that attribute like this
<input readonly onfocus="this.removeAttribute('readonly');" type="text">
what this does is you first have to remove the read only attribute by selecting the field and at that time most-likely you will populated with your own user input and stooping the autofill to take over
As per Chromium bug report #352347 Chrome no longer respects autocomplete="off|false|anythingelse", neither on forms nor on inputs.
The only solution that worked for me was to add a dummy password field:
<input type="password" class="hidden" />
<input type="password" />
By setting autocomplete to off should work here I have an example which is used by google in search page. I found this from inspect element.
edit:
In case off isn't working then try false or nofill. In my case it is working with chrome version 48.0
Well since we all have this problem I invested some time to write a working jQuery extension for this issue. Google has to follow html markup, not we follow Google
(function ($) {
"use strict";
$.fn.autoCompleteFix = function(opt) {
var ro = 'readonly', settings = $.extend({
attribute : 'autocomplete',
trigger : {
disable : ["off"],
enable : ["on"]
},
focus : function() {
$(this).removeAttr(ro);
},
force : false
}, opt);
$(this).each(function(i, el) {
el = $(el);
if(el.is('form')) {
var force = (-1 !== $.inArray(el.attr(settings.attribute), settings.trigger.disable))
el.find('input').autoCompleteFix({force:force});
} else {
var disabled = -1 !== $.inArray(el.attr(settings.attribute), settings.trigger.disable);
var enabled = -1 !== $.inArray(el.attr(settings.attribute), settings.trigger.enable);
if (settings.force && !enabled || disabled)
el.attr(ro, ro).focus(settings.focus).val("");
}
});
};
})(jQuery);
Just add this to a file like /js/jquery.extends.js and include it past jQuery.
Apply it to each form elements on load of the document like this:
$(function() {
$('form').autoCompleteFix();
});
jsfiddle with tests
Try the following jQuery code which has worked for me.
if ($.browser.webkit) {
$('input[name="password"]').attr('autocomplete', 'off');
$('input[name="email"]').attr('autocomplete', 'off');
}
Here's a dirty hack -
You have your element here (adding the disabled attribute):
<input type="text" name="test" id="test" disabled="disabled" />
And then at the bottom of your webpage put some JavaScript:
<script>
setTimeout(function(){
document.getElementById('test').removeAttribute("disabled");
},100);
</script>
Different solution, webkit based. As mentioned already, anytime Chrome finds a password field it autocompletes the email. AFAIK, this is regardless of autocomplete = [whatever].
To circumvent this change the input type to text and apply the webkit security font in whatever form you want.
.secure-font{
-webkit-text-security:disc;}
<input type ="text" class="secure-font">
From what I can see this is at least as secure as input type=password, it's copy and paste secure. However it is vulnerable by removing the style which will remove asterisks, of course input type = password can easily be changed to input type = text in the console to reveal any autofilled passwords so it's much the same really.
I've finally found success using a textarea. For a password field there's an event handler that replaces each character typed with a "•".
I've faced same problem. And here is the solution for disable auto-fill user name & password on Chrome (just tested with Chrome only)
<!-- Just add this hidden field before password as a charmed solution to prevent auto-fill of browser on remembered password -->
<input type="tel" hidden />
<input type="password" ng-minlength="8" ng-maxlength="30" ng-model="user.password" name="password" class="form-control" required placeholder="Input password">

It still works great despite a few comments below. There are no problems with accessibility because the fields are display:none meaning they don't get focus. As I mentioned you need to put them before your real fields.
If you are using javascript to modify your form, there is an extra trick you will need. Show the fake fields while you are manipulating the form and then hide them again a millisecond later.
Example code using jQuery (assuming you give your fake fields a class):
$(".fake-autofill-fields").show();
// some DOM manipulation/ajax here
window.setTimeout(function () {
$(".fake-autofill-fields").hide();
}, 1);
Update July 2018
My solution no longer works so well since Chrome's anti-usability experts have been hard at work. But they've thrown us a bone in the form of:
<input type="password" name="whatever" autocomplete="new-password" />
This works and mostly solves the problem.
However, it does not work when you don't have a password field but only an email address. That can also be difficult to get it to stop going yellow and prefilling. The fake fields solution can be used to fix this.
In fact you sometimes need to drop in two lots of fake fields, and try them in different places. For example, I already had fake fields at the beginning of my form, but Chrome recently started prefilling my 'Email' field again - so then I doubled down and put in more fake fields just before the 'Email' field, and that fixed it. Removing either the first or second lot of the fields reverts to incorrect overzealous autofill.
Update Mar 2020
It is not clear if and when this solution still works. It appears to still work sometimes but not all the time.
In the comments below you will find a few hints. One just added by #anilyeni may be worth some more investigation:
As I noticed, autocomplete="off" works on Chrome 80, if there are fewer than three elements in <form>. I don't know what is the logic or where the related documentation about it.
Also this one from #dubrox may be relevant, although I have not tested it:
thanks a lot for the trick, but please update the answer, as display:none; doesn't work anymore, but position: fixed;top:-100px;left:-100px; width:5px; does :)
Update APRIL 2020
Special value for chrome for this attribute is doing the job: (tested on input - but not by me)
autocomplete="chrome-off"
After months and months of struggle, I have found that the solution is a lot simpler than you could imagine:
Instead of autocomplete="off" use autocomplete="false" ;)
As simple as that, and it works like a charm in Google Chrome as well!
August 2019 update (credit to #JonEdiger in comments)
Note: lots of info online says the browsers now treat autocomplete='false' to be the same as autocomplete='off'. At least as of right this minute, it is preventing autocomplete for those three browsers.
Set it at form level and then for the inputs you want it off, set to some non-valid value like 'none':
<form autocomplete="off">
<input type="text" id="lastName" autocomplete="none"/>
<input type="text" id="firstName" autocomplete="none"/>
</form>
Sometimes even autocomplete=off won't prevent filling in credentials into wrong fields.
A workaround is to disable browser autofill using readonly-mode and set writable on focus:
<input type="password" readonly onfocus="this.removeAttribute('readonly');"/>
The focus event occurs at mouse clicks and tabbing through fields.
Update:
Mobile Safari sets cursor in the field, but does not show virtual keyboard. This new workaround works like before, but handles virtual keyboard:
<input id="email" readonly type="email" onfocus="if (this.hasAttribute('readonly')) {
this.removeAttribute('readonly');
// fix for mobile safari to show virtual keyboard
this.blur(); this.focus(); }" />

Explanation: Browser auto fills credentials to wrong text field?
filling the inputs incorrectly, for example filling the phone input with an email address
Sometimes I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess, the browser looks for a password field to insert your saved credentials. Then it autofills username into the nearest textlike-input field , that appears prior the password field in DOM (just guessing due to observation). As the browser is the last instance and you can not control it,
This readonly-fix above worked for me.
If you are implementing a search box feature, try setting the type attribute to search as follows:
<input type="search" autocomplete="off" />
This is working for me on Chrome v48 and appears to be legitimate markup:
https://www.w3.org/wiki/HTML/Elements/input/search
I don't know why, but this helped and worked for me.
<input type="password" name="pwd" autocomplete="new-password">
I have no idea why, but autocomplete="new-password" disables autofill. It worked in latest 49.0.2623.112 chrome version.
Try this. I know the question is somewhat old, but this is a different approach for the problem.
I also noticed the issue comes just above the password field.
I tried both the methods like
<form autocomplete="off"> and <input autocomplete="off"> but none of them worked for me.
So I fixed it using the snippet below - just added another text field just above the password type field and made it display:none.
Something like this:
<input type="text" name="prevent_autofill" id="prevent_autofill" value="" style="display:none;" />
<input type="password" name="password_fake" id="password_fake" value="" style="display:none;" />
<input type="password" name="password" id="password" value="" />
Hope it will help someone.
For me, simple
<form autocomplete="off" role="presentation">
Did it.
Tested on multiple versions, last try was on 56.0.2924.87
You have to add this attribute :
autocomplete="new-password"
Source Link : Full Article
It is so simple and tricky :)
google chrome basically search for every first visible password element inside the <form>, <body> and <iframe> tags to enable auto refill for them, so to disable this you need to add a dummy password element as the following:
if your password element inside a <form> tag you need to put the dummy element as the first element in your form immediately after <form> open tag
if your password element not inside a <form> tag put the dummy element as the first element in your html page immediately after <body> open tag
You need to hide the dummy element without using css display:none so basically use the following as a dummy password element.
<input type="password" style="width: 0;height: 0; visibility: hidden;position:absolute;left:0;top:0;"/>
Here are my proposed solutions, since Google are insisting on overriding every work-around that people seem to make.
Option 1 - select all text on click
Set the values of the inputs to an example for your user (e.g. your#email.com), or the label of the field (e.g. Email) and add a class called focus-select to your inputs:
<input type="text" name="email" class="focus-select" value="your#email.com">
<input type="password" name="password" class="focus-select" value="password">
And here's the jQuery:
$(document).on('click', '.focus-select', function(){
$(this).select();
});
I really can't see Chrome ever messing with values. That'd be crazy. So hopefully this is a safe solution.
Option 2 - set the email value to a space, then delete it
Assuming you have two inputs, such as email and password, set the value of the email field to " " (a space) and add the attribute/value autocomplete="off", then clear this with JavaScript. You can leave the password value empty.
If the user doesn't have JavaScript for some reason, ensure you trim their input server-side (you probably should be anyway), in case they don't delete the space.
Here's the jQuery:
$(document).ready(function() {
setTimeout(function(){
$('[autocomplete=off]').val('');
}, 15);
});
I set a timeout to 15 because 5 seemed to work occasionally in my tests, so trebling this number seems like a safe bet.
Failing to set the initial value to a space results in Chrome leaving the input as yellow, as if it has auto-filled it.
Option 3 - hidden inputs
Put this at the beginning of the form:
<!-- Avoid Chrome autofill -->
<input name="email" class="hide">
CSS:
.hide{ display:none; }
Ensure you keep the HTML note so that your other developers don't delete it! Also ensure the name of the hidden input is relevant.
Use css text-security: disc without using type=password.
html
<input type='text' name='user' autocomplete='off' />
<input type='text' name='pass' autocomplete='off' class='secure' />
or
<form autocomplete='off'>
<input type='text' name='user' />
<input type='text' name='pass' class='secure' />
</form>
css
input.secure {
text-security: disc;
-webkit-text-security: disc;
}
Previously entered values cached by chrome is displayed as dropdown select list.This can be disabled by autocomplete=off , explicitly saved address in advanced settings of chrome gives autofill popup when an address field gets focus.This can be disabled by autocomplete="false".But it will allow chrome to display cached values in dropdown.
On an input html field following will switch off both.
Role="presentation" & autocomplete="off"
While selecting input fields for address autofill Chrome ignores those input fields which don't have preceding label html element.
To ensure chrome parser ignores an input field for autofill address popup a hidden button or image control can be added between label and textbox. This will break chrome parsing sequence of label -input pair creation for autofill.
Checkboxes are ignored while parsing for address fields
Chrome also considers "for" attribute on label element. It can be used to break parsing sequence of chrome.
In some cases, the browser will keep suggesting autocompletion values even if the autocomplete attribute is set to off. This unexpected behavior can be quite puzzling for developers. The trick to really forcing the no-autocompletion is to assign a random string to the attribute, for example:
autocomplete="nope"
I've found that adding this to a form prevents Chrome from using Autofill.
<div style="display: none;">
<input type="text" id="PreventChromeAutocomplete" name="PreventChromeAutocomplete" autocomplete="address-level4" />
</div>
Found here. https://code.google.com/p/chromium/issues/detail?id=468153#hc41
Really disappointing that Chrome has decided that it knows better than the developer about when to Autocomplete. Has a real Microsoft feel to it.
<input readonly onfocus="this.removeAttribute('readonly');" type="text">
adding readonly attribute to the tag along with the onfocus event removing it fixes the issue
In 2016 Google Chrome started ignoring autocomplete=off though it is in W3C. The answer they posted:
The tricky part here is that somewhere along the journey of the web autocomplete=off become a default for many form fields, without any real thought being given as to whether or not that was good for users. This doesn't mean there aren't very valid cases where you don't want the browser autofilling data (e.g. on CRM systems), but by and large, we see those as the minority cases. And as a result, we started ignoring autocomplete=off for Chrome Autofill data.
Which essentially says: we know better what a user wants.
They opened another bug to post valid use cases when autocomplete=off is required
I haven't seen issues connected with autocomplete throught all my B2B application but only with input of a password type.
Autofill steps in if there's any password field on the screen even a hidden one.
To break this logic you can put each password field into it's own form if it doesn't break your own page logic.
<input type=name >
<form>
<input type=password >
</form>
For username password combos this is an easy issue to resolve. Chrome heuristics looks for the pattern:
<input type="text">
followed by:
<input type="password">
Simply break this process by invalidating this:
<input type="text">
<input type="text" onfocus="this.type='password'">
Mike Nelsons provided solution did not work for me in Chrome 50.0.2661.102 m.
Simply adding an input element of the same type with display:none set no longer disables the native browser auto-complete. It is now necessary to duplicate the name attribute of the input field you wish to disable auto-complete on.
Also, to avoid having the input field duplicated when they are within a form element you should place a disabled on the element which is not displayed. This will prevent that element from being submitted as part of the form action.
<input name="dpart" disabled="disabled" type="password" style="display:none;">
<input name="dpart" type="password">
<input type="submit">
There's two pieces to this. Chrome and other browsers will remember previously entered values for field names, and provide an autocomplete list to the user based on that (notably, password type inputs are never remembered in this way, for fairly obvious reasons). You can add autocomplete="off" to prevent this on things like your email field.
However, you then have password fillers. Most browsers have their own built-in implementations and there's also many third-party utilities that provide this functionality. This, you can't stop. This is the user making their own choice to save this information to be automatically filled in later, and is completely outside the scope and sphere of influence of your application.
If you're having issues with keeping placeholders but disabling the chrome autofill I found this workaround.
Problem
HTML
<div class="form">
<input type="text" placeholder="name"><br>
<input type="text" placeholder="email"><br>
<input type="text" placeholder="street"><br>
</div>
http://jsfiddle.net/xmbvwfs6/1/
The above example still produces the autofill problem, but if you use the required="required" and some CSS you can replicate the placeholders and Chrome won't pick up the tags.
Solution
HTML
<div class="form">
<input type="text" required="required">
<label>Name</label>
<br>
<input type="text" required="required">
<label>Email</label>
<br>
<input type="text" required="required">
<label>Street</label>
<br>
</div>
CSS
input {
margin-bottom: 10px;
width: 200px;
height: 20px;
padding: 0 10px;
font-size: 14px;
}
input + label {
position: relative;
left: -216px;

}
input:invalid + label {

I really did not like making hidden fields, I think that making it like that will get really confusing really fast.
On the input fields that you want to stop from auto complete this will work. Make the fields read only and on focus remove that attribute like this
<input readonly onfocus="this.removeAttribute('readonly');" type="text">
what this does is you first have to remove the read only attribute by selecting the field and at that time most-likely you will populated with your own user input and stooping the autofill to take over
As per Chromium bug report #352347 Chrome no longer respects autocomplete="off|false|anythingelse", neither on forms nor on inputs.
The only solution that worked for me was to add a dummy password field:
<input type="password" class="hidden" />
<input type="password" />
By setting autocomplete to off should work here I have an example which is used by google in search page. I found this from inspect element.
edit:
In case off isn't working then try false or nofill. In my case it is working with chrome version 48.0
Well since we all have this problem I invested some time to write a working jQuery extension for this issue. Google has to follow html markup, not we follow Google
(function ($) {
"use strict";
$.fn.autoCompleteFix = function(opt) {
var ro = 'readonly', settings = $.extend({
attribute : 'autocomplete',
trigger : {
disable : ["off"],
enable : ["on"]
},
focus : function() {
$(this).removeAttr(ro);
},
force : false
}, opt);
$(this).each(function(i, el) {
el = $(el);
if(el.is('form')) {
var force = (-1 !== $.inArray(el.attr(settings.attribute), settings.trigger.disable))
el.find('input').autoCompleteFix({force:force});
} else {
var disabled = -1 !== $.inArray(el.attr(settings.attribute), settings.trigger.disable);
var enabled = -1 !== $.inArray(el.attr(settings.attribute), settings.trigger.enable);
if (settings.force && !enabled || disabled)
el.attr(ro, ro).focus(settings.focus).val("");
}
});
};
})(jQuery);
Just add this to a file like /js/jquery.extends.js and include it past jQuery.
Apply it to each form elements on load of the document like this:
$(function() {
$('form').autoCompleteFix();
});
jsfiddle with tests
Try the following jQuery code which has worked for me.
if ($.browser.webkit) {
$('input[name="password"]').attr('autocomplete', 'off');
$('input[name="email"]').attr('autocomplete', 'off');
}
Here's a dirty hack -
You have your element here (adding the disabled attribute):
<input type="text" name="test" id="test" disabled="disabled" />
And then at the bottom of your webpage put some JavaScript:
<script>
setTimeout(function(){
document.getElementById('test').removeAttribute("disabled");
},100);
</script>
Different solution, webkit based. As mentioned already, anytime Chrome finds a password field it autocompletes the email. AFAIK, this is regardless of autocomplete = [whatever].
To circumvent this change the input type to text and apply the webkit security font in whatever form you want.
.secure-font{
-webkit-text-security:disc;}
<input type ="text" class="secure-font">
From what I can see this is at least as secure as input type=password, it's copy and paste secure. However it is vulnerable by removing the style which will remove asterisks, of course input type = password can easily be changed to input type = text in the console to reveal any autofilled passwords so it's much the same really.
I've finally found success using a textarea. For a password field there's an event handler that replaces each character typed with a "•".
I've faced same problem. And here is the solution for disable auto-fill user name & password on Chrome (just tested with Chrome only)
<!-- Just add this hidden field before password as a charmed solution to prevent auto-fill of browser on remembered password -->
<input type="tel" hidden />
<input type="password" ng-minlength="8" ng-maxlength="30" ng-model="user.password" name="password" class="form-control" required placeholder="Input password">

Looking to default to numeric keyboard on mobile but easily allow text input too [duplicate]

Is there a way to force the number keyboard to come up on the phone for an <input type="text">? I just realized that <input type="number"> in HTML5 is for “floating-point numbers”, so it isn’t suitable for credit card numbers, ZIP codes, etc.
I want to emulate the numeric-keyboard functionality of <input type="number">, for inputs that take numeric values other than floating-point numbers. Is there, perhaps, another appropriate input type that does that?
You can do <input type="text" pattern="\d*">. This will cause the numeric keyboard to appear.
See here for more detail: Text, Web, and Editing Programming Guide for iOS
<form>
<input type="text" pattern="\d*">
<button type="submit">Submit</button>
</form>
As of mid-2015, I believe this is the best solution:
<input type="number" pattern="[0-9]*" inputmode="numeric">
This will give you the numeric keypad on both Android and iOS:
It also gives you the expected desktop behavior with the up/down arrow buttons and keyboard friendly up/down arrow key incrementing:
Try it in this code snippet:
<form>
<input type="number" pattern="[0-9]*" inputmode="numeric">
<button type="submit">Submit</button>
</form>
By combining both type="number" and pattern="[0-9]*, we get a solution that works everywhere. And, its forward compatible with the future HTML 5.1 proposed inputmode attribute.
Note: Using a pattern will trigger the browser's native form validation. You can disable this using the novalidate attribute, or you can customize the error message for a failed validation using the title attribute.
If you need to be able to enter leading zeros, commas, or letters - for example, international postal codes - check out this slight variant.

http://danielfriesen.name/blog/2013/09/19/input-type-number-and-ios-numeric-keypad/
I have found that, at least for "passcode"-like fields, doing something like <input type="tel" /> ends up producing the most authentic number-oriented field and it also has the benefit of no autoformatting. For example, in a mobile application I developed for Hilton recently, I ended up going with this:
... and my client was very impressed.
<form>
<input type="tel" />
<button type="submit">Submit</button>
</form>
<input type="text" inputmode="numeric">
With Inputmode you can give a hint to the browser.
Using the type="email" or type="url" will give you a keyboard on some phones at least, such as iPhone. For phone numbers, you can use type="tel".
There is a danger with using the <input type="text" pattern="\d*"> to bring up the numeric keyboard. On firefox and chrome, the regular expression contained within the pattern causes the browser to validate the input to that expression. errors will occur if it doesn't match the pattern or is left blank. Be aware of unintended actions in other browsers.
as of 2020
<input type="number" pattern="[0-9]*" inputmode="numeric">
css tricks did a really good article on it: https://css-tricks.com/finger-friendly-numerical-inputs-with-inputmode/
For me the best solution was:
For integer numbers, which brings up the 0-9 pad on android and iphone
<label for="ting">
<input id="ting" name="ting" type="number" pattern="[\d]*" />
You also may want to do this to hide the spinners in firefox/chrome/safari, most clients think they look ugly
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}
input[type=number] {
-moz-appearance:textfield;
}
And add novalidate='novalidate' to your form element, if your doing custom validation
Ps just in case you actually wanted floating point numbers after all,step to whatever precision you fancy, will add '.' to android
<label for="ting">
<input id="ting" name="ting" type="number" pattern="[\d\.]*" step="0.01" />
I think type="number" is the best for semantic web page. If you just want to change the keyboard, you can use type="number" or type="tel". In both cases, iPhone doesn't restrict user input. User can still type in (or paste in) any characters he/she wants. The only change is the keyboard shown to the user. If you want any restriction beyond this, you need to use JavaScript.
There is an easy way to achieve this type of behaviour(like if we want to use text formatting in the input field but still want the numeric keyboard to be shown):
My Input:
<input inputMode="numeric" onChange={handleInputChange} />
Tip: if you want this type of behaviour(comma-separated numbers)
then follow handleInputChange implementation (this is react based so mentioned states also)
In 2018:
<input type="number" pattern="\d*">
is working for both Android and iOS.
I tested on Android (^4.2) and iOS (11.3)
<input type="text" inputmode="decimal">
it will give u text input using numeric key-pad
All of the posted answers trigger the number only keyboard, which is not what the OP was asking. The only way I've found to trigger the type='number' keyboard on a text input is to use CSS and JS.
The trick is to create a second number input, which you overlap on top of your text input using css.
<style type="text/css">
/* hide number spinners on inputs */
input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
-webkit-appearance: none;
margin: 0;
}
input[type=number] {
-moz-appearance:textfield; /* Firefox */
}
.hidden-number {
margin-top: -26px;
}
</style>
<form method="post" action="submit.php">
<input class="form-control" type="text" name="input_name">
<input class="form-control hidden-number" type="number" id="input_name">
</form>
Using JavaScript, when your number input gains focus it will trigger the keyboard that you want. You will then have to remove the type='number' attribute, which would prevent you from entering anything other than numbers. Then transfer whatever content is in your text input to the number input. Lastly, when the number input loses focus, transfer its contents back to the text input and replace its type='number' attribute.
<script type="text/javascript">
$(".hidden-number").on("focus", function(){
$(this).removeAttr("type");
var text_input = $("input[name="+this.id+"]");
$(this).val(text_input.val());
text_input.val("");
});
$(".hidden-number").on("focusout", function(){
var text_input = $("input[name="+this.id+"]");
text_input.val($(this).val());
$(this).attr("type", "number");
});
</script>
You can try like this:
<input type="number" name="input">
<input type="submit" value="Next" formnovalidate="formnovalidate">
But be careful: If your input contains something other than a number, it will not be transmitted to the server.
I couldn't find a type that worked best for me in all situations: I needed to default to numeric entry (entry of "7.5" for example) but also at certain times allow text ("pass" for example). Users wanted a numeric keypad (entry of 7.5 for example) but occasional text entry was required ("pass" for example).
Rather what I did was to add a checkbox to the form and allow the user to toggle my input (id="inputSresult") between type="number" and type="text".
<input type="number" id="result"... >
<label><input id="cbAllowTextResults" type="checkbox" ...>Allow entry of text results.</label>
Then I wired a click handler to the checkbox that toggles the type between text and number based on whether the checkbox above is checked:
$(document).ready(function () {
var cb = document.getElementById('cbAllowTextResults');
cb.onclick = function (event) {
if ($("#cbAllowTextResults").is(":checked"))
$("#result").attr("type", "text");
else
$("#result").attr("type", "number");
}
});
This worked out well for us.
try this:
$(document).ready(function() {
$(document).find('input[type=number]').attr('type', 'tel');
});

Change URL parameters value

Let's consider the two following line:
mydomain.com?quantity=10
<input type="text" name="quantity" size="1" value="1" />
Is there any way for me to automatically change the value of "quantity" in the URL when a new value is typed by the user (by using the input) ?
Submitting the element value in a form automatically updates the URL with the current value for quantity. If you use the onchange event to trigger submit, the URL will not change until the user clicks outside the input:
<form>
<input type="text" name="quantity" size="1" value="1"
onchange="this.form.submit()" />
</form>
Variations of this could look at keyboard events whilst focus is still with the input element. It remains to be seen if reloading the page would be user friendly and it is not clear if this is indeed what you wish to happen. If you don't want to reload the page see the comment and link from #igwan regarding using the history api (check on MDN for browser support).
No. All javascript code affect only the document part of the browser. It can send you to another page where the quantity can be changed though.

How to block writing in input text?

I just creating a booking system and I want that the users will choose a date from the calender and it'll show in input text - that I did!
Now I want to block the writing in the input text (just bring to calender writes there when the user choose a date).
How do I do it? I guess JavaScript, but how? I dont know JS very wall..
Thank you very much!
Give your element the readonly attribute, this will disallow users to type anything into it. However, you will still be able to write to add through javascript for example when a date is chosen. Here is an example:
<input type="text" id="txt" readonly="readonly">
JavaScript:
var el = document.getElementById('txt');
el.value = "Testing......";
Working Demo
<input type="text" id="someId" disabled="disabled" />
The disabled property will prevent any user input, but you can still write to it via your javascript calendar method.
For those who wants to prevent typing but not having the disabled style, can try:
<input type="text" onkeypress="return false;"/>
