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. ...Rene
