Description

[Manix Rock]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6

XMLHttpRequest call onreadystatechange with "this" set to the function instead of the object

Reproducible: Always

Steps to Reproduce:
var req = new XMLHttpRequest;
req.open("GET", "http://localhost/doc.txt", false);
req.onreadystatechange = function() {
	document.write("this: "+this);
};
req.send(null);
Actual Results:  
this: function () { document.write("this: " + this); }

Expected Results:  
this: [object XMLHttpRequest]

in IE and Opera "this" correctly point to the XMLHttpRequest object.

Does this work on a firefox trunk build?

Just came across this, looks like it could be another:

"synchronous XMLHttpRequest does not fire "readystatechange" event"

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
