[jQuery] jQuery Form Plugin
I'm trying to use the beforeSubmit callback of the jQuery form plugin
to check some values with the server before submitting the entire
form, which can include a large file upload (which would be annoying
to upload, and then fail due to other submitted values being invalid--
hence the pre-submit check).
For reference: http://malsup.com/jquery/form/#code-samples
The problem I'm having with running an Ajax request within
beforeSubmit, for example, is that it returns immediately (normally a
good thing). But beforeSubmit needs to wait for the value before
knowing whether it can return true or false.
Anyone run into this before? I guess, in a nutshell, what I'm trying
to do is validate part of the form data by submitting it to a
different URL, then, depending on the response, submitting (or not
submitting) the entire form to the primary URL.
