success-event not fired on synchronous AJAX events on FF (with fix)

Description

If you do an non-asynchronous AJAX request, like so:

$.ajax({'async':false,'url':'ajax.txt',success:function(data){alert(data)}});

then the 'success' function is not called on FireFox (1.5.0.8 on WinXP).

This is because Firefox does not fire the 'onreadystatechange' event on

synchronous ajax calls. The fix is easy, just change 2 lines of code:

Line 1975 in jquery-1.0.4.js:

if(s.async) xml.onreadystatechange = onreadystatechange;

Line 1994 in jquery-1.0.4.js:

if (!s.async) onreadystatechange();

I can't confirm this (with FF 1.5.0.9). This is the test code:

test("synchronous request with callbacks", function() {
	var result;
	$.ajax({url: "data/json.php", async: false, success: function(data) { result = data; }});
	ok( /^{ "data"/.test( result ), "check returned text" );
});

Please reopen if the problem persists.

The problem does persist... If you search Google Groups, you will find many reports

about this issue: Firefox does not fire the onreadyStateChange on syncrhonous AJAX

requests.

Examples:

Example1

and

Example2

Once again, my example is this:

$.ajax({async:false,url:'ajax.txt',success:function(data){alert(data)}});

Tested on FF 1.5.0.9 on WinXP and on

FF 1.5.0.7 on Linux: both do not call the 'success' function.

Please test it as in this example, I'm sure you will find the same results.

Thanks!

Your example works just fine. Did you try if it works with "async: true"? Maybe the problem is elsewhere. Otherwise: Please setup a test page that clearly shows the problem.

Interesting. My guess: This was fixed in FF 2, therefore it works for me. Got to install FF 1.5 again.

Fixed in SVN. It is a FF1.5 only-problem, but now handled by jQuery.
