A Boolean which, if present, specifies that the form-data (inputs) should not be validated when submitted.
Why would you use this?
If it's applied to your form it allows your JavaScript to manage all validation.
If it's applied to your submit input it can be used to allow users to have the ability to leave the form completion and later on continue where they left off without being forced to fix all the validation errors.
Is this statement about formnovalidate true?
A Boolean which, if present, specifies that the form-data (inputs) should not be validated when submitted.
Yes, the statement is true. Basically it's what the documantation says. It's worth mentioning that this HTML5 attribute can be applied to <button> or <input type="submit"> and it overrides default behaviour of the form which validates all inputs before it is submitted. This default behaviour of the form can also be overriden using another HTML5 attribute - novalidate of <form> element.
If it's applied to your form it allows your JavaScript to manage all validation.
You don't apply attribute formnovalidate to a <form> element. Attribute novalidate is used for this purpose - see above. If you apply novalidate to a <form> or formnovalidate to a <button> that caused the form to submit then it effectively disables validation of form's input fields by the browser. You can still use some kind of client-side (JavaScript) validation whether or not browser validation is enabled. Disabling the validation allows the user to submit the form to server where you can also validate the form data by your backend.
If it's applied to your submit input it can be used to allow users to have the ability to leave the form completion and later on continue where they left off without being forced to fix all the validation errors.
That's true, but note that you still have to somehow store and restore the values of inputs by yourself either using local or server-side storage.
See here how combination of novalidate and formnovalidate works in real life:
form + form {
margin-top: 2em;
}
fieldset {
display: inline-block;
}
<form onsubmit="window.alert('submitted'); return false;">
<fieldset>
<legend>This form validates input on submit</legend>
<input type="text" name="some-text" placeholder="enter some non-blank text" required>
<input type="submit" value="Save" />
<input type="submit" value="Save without validation" formnovalidate />
</fieldset>
</form>
<form novalidate onsubmit="window.alert('submitted'); return false;">
<fieldset>
<legend>This form never validates input on submit</legend>
<input type="text" name="some-text" placeholder="enter some non-blank text" required>
<input type="submit" value="Save" />
<input type="submit" value="Save without validation" formnovalidate />
</fieldset>
</form>

Sometimes I just want to submit a "normal" form, but have the input fields in React (of styling reasons).
But the form doesn't seem to "see" the values of the input fields when submitting.
<form action="comments" method="post">
<label>
Name:
<input
className={styles.input}
defaultValue="Bob"
type="text"
ref={this.input} />
</label>
<input type="submit" value="Submit" />
</form>
Is there a way to accomplish something like the above, i.e. posting a form without having to create an onSubmit event handler that referes to every single field in the form?
Ps. I'm aware that the default React way is to include state, but that increases the boilerplate code even more.
use name tag in your input
e.g.
<input name="comment" type="text" defaultValue="Bob"/>
When I submit form by using below function it is submitting but values are not passed through this function. I use all functions but nothing found:
document.getElementById("postad").submit();
Form is given below.
<form action="register.php" id="postad" method="post">
<input class="textfield2" type="text" id="post_title" style="width:640px;" placeholder="Ad Title" onBlur="check('post_title')" />
<input class="button" type="button" name="save" value="Publish" onclick="send();" />
</form>
Your form contains two form controls. Neither will be a successful control (i.e. one that appears in the submitted data), but for different reasons.
Only form controls with name attributes can be successful. Your text input doesn't have a name. (It also doesn't have a default value, so you need to type in it first).
Buttons can only be successful if they are the submit button used to submit the form. Your button isn't a submit button and you use JavaScript to submit the form.
There is no name attribute in your input text fields
<input name="post_title" class="textfield2" type="text" id="post_title" style="width:640px;" placeholder="Ad Title" onBlur="check('post_title')" />

I'm relatively new to AngularJS and I am trying to sumbit a regular form. I have basic form that looks like this:
<form method="post" enctype="multipart/form-data">
input type="text" class="title span5" name="post_title" placeholder="A catchy title here..." value="" />
<input type="file" name="post_image" />
<input type="submit" class="btn btn-success" value="Create Post" />
</form>
But I noticed that AngularJS adds its own values to the form.
<form method="post" enctpye="multipart/form-data" class="ng-pristine ng-valid">
And I am ununable to submit the form. How can I disable the automatic validation that Angular JS is adding to the app?
Quoted from the documentation:
For this reason, Angular prevents the default action (form submission to the server) unless the element has an action attribute specified.
IMHO, you should read the doc to gain some general understanding of single page application, and the reason why angular's preventing the default behavior.
UPDATE : This does NOT work ... well at least not in a way you'd like it to. Adding ng-non-bindable to the form or any input breaks ALL binding. So, your ng-model in the inputs won't work anymore.
ng-non-bindable is possibly your best choice. It will prevent AngularJS from doing ANY validation. So, you'll be responsible for showing invalid and checking validity.

I have an html form that I want to only submit from a button located outside my form. I am using javascript to perform some verification and do not want the form to submit unless my javascript functions succeed. I found that if I have the button inside the form it will always submit regardless of the javascript, but if I have it outside the form when a user presses enter it simply submits the form. How can I force enter to perform the button javascript instead of submitting?
<form name="form1" action=<?$_SERVER["PHP_SELF"].'?'.$_SERVER["QUERY_STRING"]?> method="post">
<input type="text" maxlength="5" size="5" name="frmZip" value="">
<input type="hidden" name="frmLat" value="200">
<input type="hidden" name="frmLng" value="200">
<input type="submit" disabled="disabled" style="display:none" />
</form>
<button type="button" id="GetCoordinates" onclick="doClick();">Find Stores</button>
EDIT:
Found my solution.
I changed from
</form>
<button type="button" id="GetCoordinates" onclick="doClick();">Find Stores</button>
to
<input type="button" name="frmSubmit" onclick="doClick();" value="Submit">
</form>
This prevented the button from submitting the form so I submitted it in my doClick() via javascript.
EDIT 2:
While this seemed to work for a time, it has stopped catching the enter keystroke. I updated my button to:
<input type="submit" name="frmSubmit" onclick="return doClick();" value="Find Stores">
And always returned false in doClick(). This allowed me to submit the form via javascript once everything had executed.
While this doesn't answer your direct question, you can actually keep the button and simply use your validation on the form submit:
<form onsubmit="return validateForm()">
Then, in your validateForm method, return true or false indicating whether or not the validation has passed.
However to answer your direct question, you can also use the same approach on the submit button which will prevent the form from being submitted.
Update
As pointed out in the comments, an unontrusive solution is often desirable so here's that:
document.getElementById('theForm').onsubmit = function() { return validateForm(); };
Your button inside the form will not submit the form on enter if you add preventDefault...
$("form").submit(function(e) {e.preventDefault();});
So for example I have a simple HTML form:
<h3>
Login
</h3>
<div id="tabs-login">
<form method="get" action="./dev.html">
<fieldset>
<legend>
Email:
</legend>
<input type="text" class="required email" name="login" />
</fieldset>
<fieldset>
<legend>
Password:
</legend>
<input type="password" class="required" name="pass" />
</fieldset>
<input type="submit" value="Submit" />
</form>
</div>
And I use jQuery to validte it:
<script>
$(document).ready(function() { $("form").validate(); });
</script>
I want on form submition to take user inputed password value and take SHA256 from it via this jQuery plugin and submit email=user-inputed-value and pass=sha-value. How to access validated values via jQuery and change them and send to original form destination?
First -- I want to point out that I don't think this is a good idea. It's generally a bad idea to implement password hashing on the client side. Instead, the pass should be sent in plain text (over HTTPS) to the server, where it is then hashed using your preferred algorithm before storage. This has the added benefit of not advertising to potential attackers which hashing method is used, since that code exists only on the server.
That said: you're going to want to calculate that SHA value prior to form submit.
You could bind an event handler to the password field's blur event to update a hidden field's value with the new hash. Or you could add the update logic to the validation code.
Regardless of where the extra code goes, it will be much easier for you to prepare the hash prior to the form submit than it will be to send a second submission chasing after the first.
E.g.
<!-- add this to the form -->
<input type="hidden" name="sha_pass" value="" />
// add this to the document ready handler
$('[name=pass]').blur(function() {
$('[name=sha_pass]').val($.sha256($(this).val());
});
