Submit Form with Enter Key [duplicate] - javascript

I have set up a bootstrap modal with a form inside it, I just noticed that when I press the Enter key, the modal gets dismissed.
Is there a way not to dismiss it when pressing Enter?
I tried activating the modal with keyboard:false, but that only prevents dismissal with the ESC key.

I just had this problem too.
My problem was that i had a close button in my modal
<button class="close" data-dismiss="modal">×</button>
Pressing enter in the input field caused this button to be fired. I changed it to an anchor instead and it works as expected now (enter submits the form and does not close the modal).
<a class="close" data-dismiss="modal">×</a>
Without seeing your source, I can't confirm that your cause is the same though.

Just add the type="button" attribute to the button element, some browsers interpret the type as submit by default.
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#Attributes
This applies for all the buttons you have in the modal.
<button type="button" class="close" data-dismiss="modal">×</button>

I had this problem even after removing ALL buttons from my Bootstrap Modal, so none of the solutions here helped me.
I found that a form with a single text field would cause the browser to do a form submit (and result in dismiss), if you hit Enter while keyboard focus is on the text field. This seems to be more of a browser/form issue than anything with Bootstrap.
My solution was to set the form's onsubmit attribute to onsubmit="return false"
This may be a problem if you are actually using the submit event, but I'm using JS frameworks that generate AJAX requests rather than doing a browser submit, so I prefer disabling submit entirely. (It also means I don't have to manually tweak every form element that might trigger a submit).
More info here: Bootstrap modal dialogs with a single text input field always dismiss on Enter key

I had same problem, and i solved it with
<form onsubmit="return false;">
but there is one more solution, you can add dummy invisible input, so your form would look like this:
<form role="form" method="post" action="submitform.php">
<input type="text" id="name" name="name" >
<input type="text" style="display: none;">
</form>

You can put the login button before the cancel button and this would solve the issue you are having as well.
<div class="modal-footer">
<button type="submit" class="btn primary">Login</button>
<button type="submit" class="btn" data-dismiss="modal">Cancel</button>
</div>

I had a similar experience just now and the way I solved it was instead of using a tag, I changed the tag to an tag with type="button". This seemed to solve the problem of pressing the "enter" key and dismissing the bootstrap modal.

I had this problem too and I solved it this way. I added onsubmit to form. I also wanted to be able to use enter key as a saving key so I added save_stuff() javascript to onsubmit. return false; is used to prevent the form submit.
<form onsubmit="save_stuff(); return false;">
...
</form>
<script>
function save_stuff(){
//Saving stuff
}
</script>

ReactJS bootstrap form without refreshing page

I have a form in my very basic React app where I want to allow the user to enter text and create their username by updating state. However when the "OK" button is clicked, the created username appears on the page for about half a second then the page auto-refreshes and restores the default state. It only happens when the button is contained within a form element. It works fine and the page doesn't refresh when I remove the form element, however I don't want to sacrifice the style and formatting of the bootstrap form. Here's my render method:
render() {
return (
<div class="container-fluid text-center">
<form class="form-inline">
<input type="text" class="form-control" placeholder="UserName"/>
<button onClick={this.createUser.bind(this)} class="btn btn-primary">OK</button>
</form>
<h1>User: {this.state.userName}</h1>
<h1>Points: {this.state.points}</h1>
</div>
)
}
Your button doesn't have a type attribute, so the default will be submit (see this page). This means that when you click your button the onClick handler will be called, but the default browser action of submitting the form will also happen.
Try specifying a type of button instead:
<button type="button" onClick={this.createUser.bind(this)} class="btn btn-primary">OK</button>
Also, if you don't specifically need a form element you could try changing it to a <div>. The bootstrap form-inline style doesn't require a form, as mentioned in the documentation under the Inline form heading:
Add .form-inline to your form (which doesn't have to be a <form>)...

Parsley: How to prevent validation when pressing buttons other than submit?

Thank you for any help.
I am trying to use Parsley for Form Validation. My form has one submit button and some other buttons to dynamically add inputs to the form. But when I press these other buttons, form validation is carried out. But I am not submitting any form.
How to prevent form validation from happening when I press other buttons than submit button?
Sorry, I dont know how to JS Fiddle. My code is like the following:
<form method="post" action="confirm" data-parsley-validate>
<input id="brand" data-parsley-trigger="submit" required />
<button id="addQuantity">Add</button>
<input type="number" required data-parsley-trigger="submit" />
<input type="submit" value="Submit">
</form>
When I press Add, the form is validated. How should I prevent this?
Thank you very much.
The tag button which was introduced in HTML5 is equivalent to input type="submit" hence when you press add it will automatically fire submit action. What you can do is replace the tag to input type="button" or you can prevent the default action in jquery like this
<script>
$('#addQuantity').click(function(event)
{
event.preventDefault();
//do your action goes below
});
</script>
I found adding formnovalidate to the button skipped form validation for the form only when clicking that button.

Input validation Javascript

In a Windows 8 Javascript app I'm trying to validate the user's input and keep the results on screen after the user presses Apply by using the following:
<form>
<input id="test" type="number" min="1" max="10" />
<button id="button" type="button">Apply</button>
</form>
But when I click Apply the validation doesn't work. It only works if I replace type="button" with type="submit". The problem is that submit refreshes the page and the results disappear. What can I do?
Here is an example of what I'm trying to do: JSFiddle
UPDATE:
I changed my code to this:
<buton id="button" type="submit" onsubmit="doTest(); return false;">Apply</button>
but it still refreshes my page.
Form validation does not fire until the onSubmit event fires, the behavior is as designed.
One thing you could do is set the for to have an "onSubmit" event, change the button to a submit type, then in the onSubmit function call the event.stopPropigation to stop the page from doing a full postback.

Best way to form submission without using form action in JavaScript

I am building a PhoneGap application using JavaScript, HTML and jQuery Mobile.
All the HTML is in the same file, separated into <div data-role="page"> as pages.
Several pages have a form including one or more text/selection input and a submit button.
The submit is not a traditional form submit button but a button which using onClick runs a JavaScript function which can do many things.
I want the form to have this features:
When pressing the button and after running the function, clear the form.
In some cases the function should change the page.
The enter button on one of the inputs should submit the form (Activate the function).
Should I use the form HTML tag? If so what should I use for action? How to clear the form?
etc.
If you are trying to bind onClick to an input type="submit" then you're gonna have a bad time.
Unfortunately even if you return false or e.preventDefault when clicking that button, the form still sends the submit trigger so once your onClick code is finished then it will submit.
Example:
<form action="woot.php" method="POST">
<input type="submit" value="submit" onClick="alert('You clicked me! How could you?! It's cool the form will still go to woot.php. return FALSE wont help you either.'); return FALSE;">
</form>
What you probably want to do:
<form action="woot.php" method="POST">
<input type="submit" value="Submit" onSubmit="alert('You aint goin nowhere!'); return FALSE;">
</form>
What you should do:
<form action="woot.php" method="POST">
<input type="button" value="Button" onClick="alert('Away with you!'); window.location = 'http://www.google.com/';">
<input type="button" value="Button" onClick="someCoolFunction();">
</form>
I wouldn't use type="button", especially if you want to have the best chance of the form submitting when the user presses enter.
Use your regular form <input type="submit"> and then your JavaScript:
$('form').submit(function(e) {
// all your form handling here;
if (your_form_was_validated_and_handled) {
$('input[type!="submit"]').val('');
}
e.preventDefault();
});
Generic fiddle: http://jsfiddle.net/
You can still use the form tag, as it's useful for markup.
Just make sure that your buttons have attribute
type="button"
otherwise the button will submit the form by default.
To reset the form:
function resetForm() {
$('#form').each(function(){
this.reset();
});
}

How to prevent form submit from triggering `button:first.onclick()`?

Every time I submit a form by pressing enter, the click() function on the first <button> in the associated form is getting triggered. The problem (other than the fact that I just find this behavior odd) is that it is literally a click event, indistinguishable from actually clicking on the button. If it triggered the even on my submit button, I'd be fine with it.
The issue is that in this case the first button has nothing to do with the actual form, it's actually in a hidden popup.
So the exact question: Why is this happening? How do I prevent it? How do I distinguish this "fake click" event from a real one?
(this is a very simplified example; actual code is using jQuery (in case jQuery happens to acknowledge this and there is a fix for it), but the actual issue has nothing to do with jQuery)
<form>
<input>
<button onclick="alert('button A click');">Button A</button>
<button onclick="alert('button B click');">Button B</button>
<input type="submit" value="Submit Button">
</form>
http://jsfiddle.net/NexHC/2/
Please, no suggestions to "move the button"
-snip-
Edit
<form>
<input>
<button type="button" onclick="alert('button A click');">Button A</button>
<button type="button" onclick="alert('button A click');">Button B</button>
<input type="submit" onclick="alert('button Submit click');" value="Submit Button">
</form>
Actually I take it back... the reason is a lot more concrete and simple than that. Submit is the default type for <button> as specified by the w3c. Therefore, by leaving the button type attributes blank on your form, you were making three submit buttons and it was picking the first when you hit enter (love the <kbd> styling on this site :P). See here for w3c info and here for the updated fiddle
My advice would be, if the <button> has nothing to do with the form and is also controlling a hidden popup, then take it out of the context of the <form> and place it elsewhere. This would also solve your click issue.
