I have searched for this topic but couldn't find anything useful.
In my case I have a jQuery-ui button with a click event. This click event works fine, but it always gets invoked by pressing enter in a text-input-field.
Demo here: http://jsfiddle.net/vcfzJ/
Hope somebody can help. I made a workaround by checking event.target.nodeName.
This is because a button is by default a submitting element for the form, so pressing enter in the textbox submits the form.
<button>x</button> is equivalent to <button type="submit">x<button>
Use this to make the button a non-submitting element:
<button type="button">x</button>
However, it does seem strange that this would trigger the "click" event, since the button was not actually clicked, and the answer seems to be this:
$("form").submit(function() { return false; }); live test case
