The form contains a file input field, so I would be submitting Multi-part form data. How would you resolve this? 回答1: your form action would point to the site controlling the post. <form id="theForm" action="http://someurltoaformsubmitfunction" method="post"> then you can call $('#theForm').submit(); 回答2: If all you
