We'd like to use javascript (we're using Ext) to check that the upload file is under a size limit, and of a particular type (a .XXX extension would be fine) before uploading. So, of course, this would happen on the client side, preventing unnecessary uploads to the system.
This is a general problem that has been addressed elsewhere on the web, for questions like these you should search the Ext forums and the web for answers before coming to this forum (if you haven't already).
In any case, Javascript does not yet provide a way of checking the size before the upload, so you can't do that. But you can easily check the extension by checking the filename before actually sending the Ajax post. I'm sure the user is clicking a button to initiate the upload, in your handler code do the check there.
