AJAX Form plugin - wait for event
I'm using the AJAX form plugin from
http://malsup.com/jquery/form/ and I was trying to do some image pre-processing in the beforeSubmit function, but since the image processor relies on FileReader.onload, which is asynchronous, the form attempts to submit before the processing is complete.
If I simply return false in beforeSubmit, I can't seem to see how to later continue the submission from the onload callback, although I may well be missing something obvious. Any suggestions?
