If a form includes an element with a name attribute of 'disabled', the .on function does not prevent the form from being submitted (when used with a descendant selector).

This form is not prevented from submitting:

#!text/html
<form action="google.com">
    <input type="text" name="disabled" value="Some text" />
    <input type="submit" />
</form>

$(document).on('submit', 'form', false);

If the name of the text input was changed to anything other than 'disabled' the form is prevented from submitting.

Strangely, if I change the method to the following, the original form would not submit (even ''with'' the name="disabled" attribute)

$('form').on('submit', false);

Example: Two identical forms, one with name="disabled" http://jsfiddle.net/y3HVA/

Note: I am ''not'' trying to disable this field, I simply wanted to use the name 'disabled' as the attribute.
