I have a usual login form consisting of two input fields, one for login, one for password. I am currently trying to add a control that will show entered password as plain text, so user can check it for typos.
The problem is that browsers (at least Firefox) do not allow dynamic changing of type attribute of input fields, so I cannot just change type="password" to type="text". Another problem is that browsers do not allow to get value of password field, so I can't create a new input type="text" and set its value to the password's one. I've seen several different approaches to this task, including this one, but they are working only if the password is typed and fail when browser autofills the password.
So, any suggestions to do this are welcome. I am using jQuery.
You can do something like this:
<input type="password" id="password">
<input type="checkbox" onchange="document.getElementById('password').type = this.checked ? 'text' : 'password'"> Show password
If I may, I don't think it's a great idea to show the password in text, for the following reasons:
It's not commonly done, so it will be confusing to the user
It means you are open to over-the-shoulder viewing of the password
I also think, if you just want to help users avoid typos, give them more chances before the password is disabled. I think the typical "3" that most sites implement is not really required, I'd suggest "10" attempts, or perhaps "5", if you wish to be really conservative, is quite acceptable. Just count it down for them, and let them resolve typos on their own.
Just my humble opinion.
I have never tried this myself but can't you just access the value property of the element?
if you have something like...
<input id="pw" name="pw" type="password" />
Then in JavaScript / jQuery...
var pass = document.getElementById('pw').value;
$('pw').val()
There is no any possibility to show autofilled password for security reasons. Anyone could see your password on your computer for this page if this is possible.
You have to deal with following for complete solution:
javascript is not allowed - then you should not display choose password checkbox
autocomplete is turned on - as I wrote, you're not able to show password filled this way. Eaighter switch off autocomplete or hide show password until user re-type password.
Autocomplete switch off by this jQuery
$('input').attr('autocomplete', 'off');
For adding checkbox on the fly you can use following jquery-showPassword plugin available at http://www.cuptech.eu/jquery-plugins/
$('.show-password').change(function() {
if ($("#form-fields_show-password").attr('checked')) {
var showValue = $('#form-fields_password').val();
var showPassword = $('<input type="text" size="50" required="required" name="form- fields[password]" id="form-fields_password" class="password required" value="'+showValue+'">');
$('#form-fields_password').replaceWith(showPassword);
} else {
var hideValue = $('#form-fields_password').val();
var hidePassword = $('<input type="password" size="50" required="required" name="form-fields[password]" id="form-fields_password" class="password required" value="'+hideValue+'">');
$('#form-fields_password').replaceWith(hidePassword);
}
});
Something like this will find the input area, and store the value in a variable called showValue. Then you can replace the element with type="password", with new html where type="text" and if the checkbox is unchecked the value will be dropped into password type field.
There is a problem with this method in that the password type value will be visible in the code, however to get round this you can always remove the value attribute from the password type and just force the user to re-type. If you can live with that in you application.
function change(){
id.type="password";
}
<input type="text" value="123456" id="change">
<button onclick="pass()">Change to pass</button>
<button onclick="text()">Change to text</button>
<script>function pass(){document.getElementById('change').type="password";} function text(){document.getElementById('change').type="text"; } </script>
Password: <input type="password" value="" id="myInput"><br><br>
<input type="checkbox" onclick="myFunction()">Show Password
<script>
function myFunction() {
var x = document.getElementById("myInput");
if (x.type === "password") {
x.type = "text";
} else {
x.type = "password";
}
}
</script>

I want to add a show password checkbox to my form.
When a user checks that checkbox password is shown.
Most of the examples that I found are using 2 inputs, one with type="text" and the other with type="password". And switch between these inputs according to the status of the checkbox.
it is simpler to change type of input to type="text", so why people use 2 inputs?
Be careful with using type="text" as a way of showing the password, as it exposes the user to saving the password in plain text in their autocomplete settings. I think the two input box approach is probably safer as you can stop the text one from being picked up by autocomplete by using autocomplete="off"
See this artcile describing the vulnerability: https://www.foxtonforensics.com/blog/post/uncovering-plain-text-passwords-in-internet-history
probably to make it work on old versions of IE, since IE 9 and below, do not allow dynamic change of type="password" to type="text". it throws an error "Could not get the type property"
I hope ur trying to ask that u want single password input field and show password button...Below is my answer
<input type="password" name="passwd" id="txtPassword" placeholder="Password" required="required">
<input type="checkbox" id="showhide"/>
<label for="showhide" id="showhidelabel">Show Password</label>
<script type="text/javascript">
$(document).ready(function () {
$("#showhide").click(function () {
if ($("#txtPassword").attr("type")=="password") {
$("#txtPassword").attr("type", "text");
}
else{
$("#txtPassword").attr("type", "password");
}
});
});
When validating an email field [name=bar] in a form #foo, I want to switch validation of that field on and off, in relation to a checkbox.
Reading the docs, github issues and stackoverflow answers, I thought setting data-parsley-required="false" and/or data-parsley-validate="false" would be enough.
But it turns out, that all other constraints, like email, min-lenght, max-length are still validated and the input field still validates to an error condition. I would prefer it to validate to success or not at all.
<form id="foo">
<input name="bar"
maxlength="40"
value=""
class="form-control"
data-parsley-validate="false"
data-parsley-required="false"
type="email"
data-parsley-minlength="5"
data-parsley-trigger="input keyup change"
data-parsley-error-message="something is wrong">
</form>
See https://jsfiddle.net/88obg0sj/9/
So how is it possible to turn off field validation in way, it can be re-activated again?
You should tweak the excluded option, for example by adding ", [data-parsley-validate="false"]" to it.
You can follow this way:-
//destroy parsley
$('form').parsley().destroy();
//set required attribute on input to false
$('input').attr('data-parsley-required', 'false');
//reinitialize parsley
$('form').parsley();
I've used the pattern attribute to check the validity of the input and used setCustomValidity to display a custom invalidity message.
The following code has been used to show the invalidity popup for the invite code field:
<input class = "custom_form_field_input" type="text" name="inviteCode" minlength = "6" required maxlength = "6" value="" required pattern="[0-9a-zA-Z]+" autocomplete="off" oninvalid="setCustomValidity('Please enter your 6 digit Invitation Code')" onchange="try{setCustomValidity('')}catch(e){}"/>
Please find snapshots here:
Invalid Input ||
Valid Input
The problem here is that, the invalidity popup should disappear once the user starts inputting a new value, but this isn't happening.
Please help me out.
P.S. - I'm using Wordpress and I cannot easily use AJAX for validation. I am also not allowed to use plugins. Please answer accordingly.
Use oninput instead of onchange.
<input class = "custom_form_field_input" type="text" name="inviteCode" minlength = "6" required maxlength = "6" value="" required pattern="[0-9a-zA-Z]+" autocomplete="off" oninvalid="setCustomValidity('Please enter your 6 digit Invitation Code')" oninput="try{setCustomValidity('')}catch(e){}"/>

For instance in this example;
<form>
<input type="email" name="email" id="useremail" placeholder="Email Address" required> <br>
<input type="tel" name="phone" id="userphone" placeholder="Phone Number" maxlength="10" required> <br>
<input type="submit" id="sidebarformsubmit" value="Submit">
</form>
Is it possible to somehow/somewhere be able to identify that the user has inputed something in EITHER the email or phone number field. So that on submit it doesn't show "this is required".
Reword: Can at least one of the form inputs be mandatory, both is allowed as is one or the other but not none. In the above example, the user needs to have at least one form of communication whether that be phone number or email. They can have both however, but not none.
If so, how would you go about this?
You can easily capture the change events from the inputs and set the required attribute accordingly.
Like this:
var email = document.getElementById('useremail'),
phone = document.getElementById('userphone');
function onchange(){
email[phone.value?'removeAttribute':'setAttribute']('required','required');
phone[email.value?'removeAttribute':'setAttribute']('required','required');
}
email.addEventListener('change',onchange);
phone.addEventListener('change',onchange);

1) No. If you use HTML5 required on a field then that field is required. There is no way to specify interdependence.
2) Yes. You can use client-side javascript validation, generally hooked to a form submit event to do as-complex-as-you-like validation. Prevent the submit by returning false from the event handler if you don't pass validation.
3) Yes. You can do validation that can be as complex as necessary on the server when you have received the submitted form, and return directly to the form if something is wrong.
3b) You Must do validation on the server, even if you have great client-side javascript validation, otherwise I will buy things from your site for one penny. You must not trust the client.
I want to make two text field as follows
<input id="email" class="email" value = "${user.email}" />
<input id="password" class="password" display="none" />
I'd like to change my email with current password. So I want to make password text field (its default display is none) to be activated, when I try to type in email text field to change email address.
To to this, I use javascript code. How can I make a code for this?
Should I use focus() or live() for this? Please let me know.
Thanks
try
$('#email').keyup(function() {
$('#password').show();
