How can I rewrite a piece of JS that uses XHR with FormData to be backwards-compatible?

I have a piece of Javascript code that uses an XHR to POST data to a URL, but it uses FormData, which is not supported in earlier versions of Chrome. This is very handy, but I want it to be backwards-compatible, so what is the best way to rewrite the makeFormData method to return the data ready to send? The offending code is here: http...

Does a response to an xmlhttprequest call have to be XML?

Prevent Rails app from responding to unintended AJAX request from jQuery

I've built out a fairly complex Rails (2.3.8) app with a lot of jQuery ajax requests. There is an occasional bug, which I have difficultly replicating, where a jQuery $.ajax({..}) request will request a page it shouldn't (like the dash page, which is never called with an ajax request)...

For IE8 it works fine and the XML can be read - but in Firefox it works differently and there is no such attribute as "serverResponse.results[0].xml" - see below: var serverResponse = dojo.xhrPost(xhrArgs); serverResponse.results[0].xml like you get in I...
