Form attribute get/set breaks with same named input in form

[trmpowell]

Trying to get or set the attribute of a form does not work properly if there is an input in the form with the same name as the attribute trying to be gotten/set.

Example, this works:

$('#testform').attr('action', '​http://www.google.com').attr('target', 'test');

<form id="testform">

<input type="text" name="act" />

</form>

while this doesn't:

$('#testform').attr('action', '​http://www.google.com').attr('target', 'test');

<form id="testform">

<input type="text" name="action" />

</form>
