Submitting a form on 'Enter' with jQuery?

Don't know if it will help, but you can try simulating a submit button click, instead of directly submitting the form. I have the following code in production, and it works fine:

    $('.input').keypress(function(e) {
        if(e.which == 13) {
            jQuery(this).blur();
            jQuery('#submit').focus().click();
        }
    });

Note: jQuery('#submit').focus() makes the button animate when enter is pressed.

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
    return false;    //<---- Add this line
  }
});

Check out this stackoverflow answer: event.preventDefault() vs. return false

Essentially, "return false" is the same as calling e.preventDefault and e.stopPropagation().

In addition to return false as Jason Cohen mentioned. You may have to also preventDefault

e.preventDefault();

Return false to prevent the keystroke from continuing.
