jquery disable form submit on enter

jquery disable form submit on enter

I have the following javascript in my page which does not seem to be working.
$(‘form’).bind(“keypress”, function(e) {
if (e.keyCode == 13) {
e.preventDefault();
return false;
}
});

I’d like to disable submitting the form on enter, or better yet, to call my ajax form submit. Either solution is acceptable but the code I’m including above does not prevent the form from submitting.

Solutions/Answers:

Solution 1:

If keyCode is not caught, catch which:

$('#formid').on('keyup keypress', function(e) {
  var keyCode = e.keyCode || e.which;
  if (keyCode === 13) { 
    e.preventDefault();
    return false;
  }
});

EDIT: missed it, it’s better to use keyup instead of keypress

EDIT 2: As in some newer versions of Firefox the form submission is not prevented, it’s safer to add the keypress event to the form as well. Also it doesn’t work (anymore?) by just binding the event to the form “name” but only to the form id. Therefore I made this more obvious by changing the code example appropriately.

EDIT 3: Changed bind() to on()

Solution 2:

Usually form is submitted on Enter when you have focus on input elements.

We can disable Enter key (code 13) on input elements within a form:

$('form input').on('keypress', function(e) {
    return e.which !== 13;
});

Solution 3:

Even shorter:

$('myform').submit(function() {
  return false;
});

Solution 4:

$('form').keyup(function(e) {
  return e.which !== 13  
});

The event.which property normalizes event.keyCode and event.charCode. It is recommended to watch event.which for keyboard key input.

which docs.

Solution 5:

$(document).on('keyup keypress', 'form input[type="text"]', function(e) {
  if(e.which == 13) {
    e.preventDefault();
    return false;
  }
});

This solution works on all forms on website (also on forms inserted with ajax), preventing only Enters in input texts. Place it in a document ready function, and forget this problem for a life.

Solution 6:

The overkill of having to capture and test every keystroke for the ENTER key really bugs me, so my solution relies on the following browser behavior:

Pressing ENTER will trigger a click event on the submit button (tested in IE11, Chrome 38, FF 31) **
(ref: http://mattsnider.com/how-forms-submit-when-pressing-enter/ )

So my solution is to remove the standard submit button (i.e. <input type="submit">) so that the above behavior fails because there’s no submit button to magically click when ENTER is pressed. Instead, I use a jQuery click handler on a regular button to submit the form via jQuery’s .submit() method.

<form id="myform" method="post">
  <input name="fav_color" type="text">
  <input name="fav_color_2" type="text">
<button type="button" id="form-button-submit">DO IT!</button>
</form>

<script>
 $('#form-button-submit').click(function(){
    $('#myform').submit();
  });
</script>

** this behavior is not applicable if the form has only 1 input field and that field is a ‘text’ input; in this case the form will be submitted upon ENTER key even if no submit button is present in the HTML markup (e.g. a search field). This has been standard browser behavior since the 90s.
