I am trying to validate the fields using CFINPUT and then calls a popup window function to do more stuff BEFORE submitting the form but it's not working. The onclick function seems to take precedent over the CFINPUT validation. As soon as I click on the Submit button it's calling the popup window function first without validating the fields. I need it to:
first validate the fields
call the popup function
then submit the form after the popup closes itself
(p.s. I see other similar case on here but there is no answer given)
The code looks like this:
<cfform action="register.cfm" method="post">
<cfinput type="text" name="username" size="50" maxlength="100" required="yes" autofocus="on" validate="noblanks">
<cfinput type="text" name="address" size="50" maxlength="100" required="yes" validate="noblanks">
....
<input type="submit" value=" Send " onclick="popup()">
....
Please help. Thank you.
This is an old blog posting so not sure how accurate things are today but it shows how you can run the CFFORM validation via the _CF_checkTaskForm() function. So it seems like if you change the submitting of the form to a button via <input type="button" value="Send" onclick="popup(this.form)" /> then change the popup function to first validate the form via the _CF_checkTaskForm() and if that passes to proceed with the other JS you are doing.
http://www.neiland.net/blog/article/triggering-cfform-validation-when-using-ajax/
To expand on that, I just looked at a CF8 and CF11 installations and looks like the function in those is _CF_checkCFForm_1 if using that version of CF then something like this should get you in the correct direction:
<script>
popup = function(formreference) {
var check = _CF_checkCFForm_1(formreference);
if (!check) {
//if the rules failed then do not submit the form
return false;
} else {
// Do the popup
}
}
</script>
<cfform action="register.cfm" method="post">
<cfinput type="text" name="username" size="50" maxlength="100" required="yes" autofocus="on" validate="noblanks">
<cfinput type="text" name="address" size="50" maxlength="100" required="yes" validate="noblanks">
<input type="button" value=" Send " onclick="popup(this.form)" />
</cfform>
The cfinput validation you're attempting to do is the client-side equivalent to
<cfif len(trim(string)) gt 0>
(Edit: That is not to imply that you should depend wholly on client side validation. Client-side validation is more of a feature to help your visitors. Server side validation is still important.)
Which I have to say is really weak validation. Anything consisting of at least 1 non-whitespace character will pass the test. People will be able to have usernames like "!" which isn't fanstastic, but that's just some information.
On the jQuery Validate link you provided, they show an example form (along with a link of the same form in action)
<form class="cmxform" id="commentForm" method="get" action="">
<fieldset>
<legend>Please provide your name, email address (won't be published) and a comment</legend>
<p>
<label for="cname">Name (required, at least 2 characters)</label>
<input id="cname" name="name" minlength="2" type="text" required>
</p>
<p>
<label for="cemail">E-Mail (required)</label>
<input id="cemail" type="email" name="email" required>
</p>
<p>
<label for="curl">URL (optional)</label>
<input id="curl" type="url" name="url">
</p>
<p>
<label for="ccomment">Your comment (required)</label>
<textarea id="ccomment" name="comment" required></textarea>
</p>
<p>
<input class="submit" type="submit" value="Submit">
</p>
</fieldset>
</form>
<script>
$("#commentForm").validate();
</script>
This very basic example shows how simple Validate can be to install, and a simple format of
<input name="ele" type="text" required>
is exactly the same level of validation you're attempting. So, to begin with, you can almost copy and paste the code. (Aside from from the different requirements you can make, setting minlength requires a certain number of characters and requires that at least one not be whitespace).
jQuery Validate can get quite extensive but is very easy to basically install and once you become familiar, make custom classes as needed
As a final note, don't disregard the disdain for CFForm elements. It may seem like others are disregarding your question, but that's not the case.
To be honest, they began to be introduced at a different time in the life of the internet, but have always been kind of finicky to work with. Expansion to them, in the opinions of many, have not been done well and have frequently exasperated the flaws.
It's super attractive to be able to say <cfinput...required> but the tags become a nuisance and you don't easily have the fine control over them that you might desire. They're a crutch, and a rusty crutch at that.

In my polymer 2 app I have something like this:
<form class="styling" autocomplete="on">
<div class="styling" >
<label>email</label>
<input name="email" autocomplete="email">
</div>
<div class="styling" >
<label>email</label>
<input name="password" autocomplete="current-password">
</div>
<div class="styling">
<a class="styling" on-tap="doRequestFunction">Login<a>
</div>
</form>
My issue is there are a lot of sources saying what works and what doesn't and I've tried removing the outer div, I've tried changing the email to a username, I've tried to change the <a> to an <input type="submit">. I've also tried to add an invisible username input below the email input. I have a database element that does my ajax calls so ideally I'd like to just call the request function on a form submit, but there doesn't appear to be a way to do this because it wants me to perform the action with a file or something like that.
TL;DR is there a way to do this:
<form class="styling" onSubmit="doTheRequestFunction" autocomplete="on">
<div class="styling" >
<label>email</label>
<input name="email" autocomplete="email"/>
</div>
<div class="styling" >
<label>email</label>
<input name="password" autocomplete="current-password"/>
</div>
<div class="styling">
<input class="styling" type="submit">Login</input>
</div>
</form>
There doesn't appear to be a way to do this in polymer and the ways that do don't request for the users password and are depreciated anyways. Using Chrome primarily.
EDIT: Please, no JQuery, only Javascript. I don't know what JQuery is doing half the time and it's sloppy.
autocomplete is an HTML attribute (https://www.w3schools.com/tags/att_input_autocomplete.asp). It's either on or off. It's designed to tell the browser whether it should attempt to autocomplete a field or not. The default is on so you shouldn't have to set it unless you're trying to prevent the browser from autocompleting.
Try to remove all your autocomplete attributes, and submit your form. The browser should ask you if you want to save your username and password at which point it should be populated next time you come to your form.
Also, you have an bad tag on the end of your submit button: </inoput>
<input type="submit" value="Send Request"> should be fine.
Boys, I found it.
paper-input autocomplete fails to fill
This is a polymer specific issue I was having. Currently polymer requested support for their auto-fill apparently and it's still not there. This is the solution for now. Pop that bad boy into you index.html and weep tears of joy.
Just make it
<input name="password" type="password"/>
So if input field has attribute type as password it will trigger browser to remember.
I'm very new to JS. But basically, I'm creating a form. Using JavaScript, how do I take a form so that you must fill in form data?
Thanks!
HTML:
<form>
<p>First Name:</p>
<input type="text" name="firstname" class="form">
<p>Last Name:</p>
<input type="text" name="lastname" class="form">
<p>Email:</p>
<input type="text" name="email" class="form">
<p>Questions / Concerns:</p>
<textarea name="concerns" rows="5" cols="30"></textarea>
<br>
<input type="submit" name="submit" value="Submit">
<input type="reset" name="reset" value="Reset">
</form>
There are multiple ways of solving this particular problem.
The easiest way would be to use the required tag in elements:
<input type="text" name="firstname" class="form" required>
Edit: This may not work in very old browsers.But I don't believe you need to worry about that now.
Use required tag in all of your input elements which you need filling compulsorily.
Once you have your basic problem solved, look at using javascript functions for validation. Ref: https://www.w3schools.com/js/js_validation.asp
Once you know this, you can safely progress to reading on how validation is done on large projects- https://validatejs.org/
use document.getElementByTagName to get the input tag
Use addEventListner with first parameter as blur to detect input leave
Use this.value within if statement to check if empty
Alert something
var element=document.getElementByTagName(input);
element.addEventListner("blur",myFunction);
function myFunction(){
if(this.value==''){
alert ("write something");
}
}
How do you disable the autocomplete functionality in the major browsers for a specific input (or form field)?
<input type="text" id="fullname" name="fullname" class="form-control" data-required="true" value="<?php echo $_POST['fullname']?>" >
When I open this form I see the value in this input even if I didn't insert any value.
I think adding autocomplete="off" would get you an error on most browsers, furthermore, autocomplete="off" is an invalid property.
Try to check the Mozilla Developer Documentation instead.
Just use the autocomplete attribute:
<input type="text" autocomplete="off"/>
"This would be useful when a text input is one-off and unique. Like a
CAPTCHA input, one-time use codes, or for when you have built your own
auto-suggest/auto-complete feature and need to turn off the browser
default."
Source : CSS Tricks
You could generate a random string using javasript or php and add it to the end of an input name, maybe even use a delimiter to split it apart from the actual name.
In php, you could use something like the session_id for this and simply echo it to the end of the name.
<input type="text" autocomplete="off" name="example<?php echo "," . session_id()?>">
You can replace the "," with any delimiter of your choice, so long as it isn't alphanumeric. Then when processing the data submitted, you can remove it from the end of the actual name of the input field.
With a field name always being different, your browser cant autocomplete it.

Solution 1
<form name="form1" id="form1" method="post"
autocomplete="off" action="http://www.example.com/form.cgi">
This will work in Internet Explorer and Mozilla FireFox, the downside is that it is not XHTML standard.
Solution 2
The solution for Chrome is to add autocomplete="new-password" to the input type password.
Example:
<form name="myForm"" method="post">
<input name="user" type="text" />
<input name="pass" type="password" autocomplete="new-password" />
<input type="submit">
</form>
Chrome always autocomplete the data if it finds a box of type password, just enough to indicate for that box autocomplete = "new-password".
This works well for me.
Note: make sure with F12 that your changes take effect, many times browsers save the page in cache, this gave me a bad impression that it did not work, but the browser did not actually bring the changes.
Solution 3
<input type="text" id="fullname" name="fullname" autocomplete="off" class="form-control" data-required="true" value="<?php echo $_POST['fullname']?>" >

I want to simulate he old habit of a DOS programm input in a HTML from.
Think of it as an order form.
First I have bunch of form fields for entering names, addresses and so on.
After that I have several product groups.
Each group has only two fields. One for the product and another for the quantity.
Now, tabbing through the form I want to have a NEW set of two input fields for the specific group if the product field its NOT empty.
If you enter a product, you get the chance to enter another one. Entering non, you quickly tab yourself in the next group.
Now I'm thinking about and searching for the most efficient solution that offers the fastest way of entering data without using the mouse when inside this form.
I'm totally free using jquery, html5 or whatever. But I definitely want this way of input, that Turbo Pascal gave to me with a little loop and some ReadLn commands.
All suggestions are welcome
--edit
started coding:
Basic form will look like this
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Testform for a DOS-like behavior</title>
</head>
<body>
<pre>
<?php print_r($_POST); ?>
</pre>
<form action="testform.php" method="post" id="formmail">
<fieldset id="person">
<legend>Person</legend>
<label for="name">Name:</label>
<input type="text" name="name" id="name" value="">
<br>
<label for="email">E-Mail:</label>
<input type="text" name="email" id="email" value="">
<br>
<label for="phone">Phone:</label>
<input type="text" name="phone" id="phone" value="">
</fieldset>
<fieldset id="productgroup1">
<legend>Product Group 1</legend>
Product: <input type="text" name="product[1][]">
Qty: <input type="text" name="qty[1][]">
</fieldset>
<input class="button" type="submit" value="Submit">
</form>
</body>
</html>
* Update
Discovering the powers of fiddle I made this: http://jsfiddle.net/zarquon42/HcbfH/
And it is basically what I want. That surprises me. Now I'm going to take a look if it works also in the context with several groups of input fields.
* Next Update
Much shorter with some jquery: http://jsfiddle.net/zarquon42/NdD7v/
perhaps you could use the JQuery terminal emulator plugin?

Hope this helps!
I have a simple form. On submit (the submit action is a google docs form submission), it takes to a new page with focus on that page. I want to keep the focus on the current page.
What are my options?
This is the code (also present here )
<html><body>
<form action="https://docs.google.com/a/rangde.org/spreadsheet/formResponse?formkey=dFlSZkt0TzZTWHJyblBiQlNrcmZvZGc6MQ" method="POST" id="ss-form" target="_blank" onsubmit="submitted=true;">
<br>
<input type="text" name="entry.0.single" value="" class="ss-q-short" id="entry_0" placeholder="Your Name">
<br>
<input type="text" name="entry.1.single" value="" class="ss-q-short" id="entry_1" placeholder="E-mail Address">
<br>
<input type="text" name="entry.2.single" value="" class="ss-q-short" id="entry_2" placeholder="Pledge Amount">
<br>
<input type="submit" name="submit" value="Submit"></form>
</body>
</html>
Depending on what you're trying to do with the resulting form, (and if you're not comfortable relying js do all the lifting) you could also create a hidden iframe on the page, give it a name, and set the form target to the name of the iframe. This is only if you have no interest in having the user ever see the google page itself.
Try AjaxForm, as found at http://jquery.malsup.com/form/, if you're using jQuery
A form's action parameter will always take you to that page.
Here is an example:
