I have a form that I ajaxForm(), that posts to a script.
My cart_account script then tries various $('#id')..... stuff.
This is ok:
<form id='id_test' name='test' action='/bin/cart_account.php' method='post'>
This fails, when enctype is specified.
<form enctype='multipart/form-data' id='id_test' name='test' action='/bin/cart_account.php' method='post'>
The form will post, but any use of $, or calling any functions from the original page will result in undefined errors. This is the case whether I specify dataType : 'script' in the ajaxForm options or not.
