oh.. I forgot to say, that when I remove the timeout option from the reqest, that it works, without a error.

This error also happens in IE 7 for example:

$(document).ready(function() {
		success: ExibeJSON,
		error: ExibeErro			

function ExibeErro(XMLHttpRequest,textStatus,errorThrown) {

function ExibeJSON(jn) {

I get it too, using IE7. It happens on the line "if (xhr.readyState == 0)" in the following fragment of 1.3.2 (line 3555):

// Wait for a response to come back
var onreadystatechange = function(isTimeout){
	// The request was aborted, clear the interval and decrement
	if (xhr.readyState == 0) {
		if (ival) {
			// clear poll interval
			ival = null;
			// Handle the global AJAX counter
			if ( && ! )
				jQuery.event.trigger( "ajaxStop" );

In FF3, no error.

I get it too, using IE7. Can't say really where it is happening, a bunch of messy code in the page

I get it too with IE. Fixed by changing first if(J.readyState... check to if(J&&J.readyState... so it checks if object exists in first place.

I can confirm that this bug happens to me every time an ajax timeout event fires in IE 8. Very annoying.

Also getting this issue - just enabled system-wide reporting of JS errors back to server, and this is the error i am getting. Should it not come into error handler?

This was fixed in 1.4. If you're having a problem with $.ajax in 1.4, please look for another ticket to open, ask for help on the forums, or create a new ticket with a clear test case.
