Description
Hi,
I have no idea what is happening. So maybe you can help me.
When a pending ajax request is aborted in IE browsers there is a new global object called "jQuery" + (random number?), for example "jQuery16405272192696596443".
This happens in every IE from 6 to 9 but not in Chrome, Safari, FireFox in their current stable versions. I am a bit lost and found nothing similar. I created a little test page to determine whether it started due to some own code or just in this little piece.
Example HTML:
<!DOCTYPE html>
<html>
<head>
<title>title</title>
<script src="http://code.jquery.com/jquery-1.6.4.js"></script>
</head>
<body>
<div id="output"></div>
<script>
$(function() {
var ajaxRequest = $.ajax("foobar.html", { cache: false });
ajaxRequest.abort();
var prop;
for (prop in window) {
if (prop.indexOf("jQuery") === 0) {
$("#output").append($("<p>").html("global jQuery object: " + prop));
}
}
});
</script>
</body>
</html>
Output in IE6-9:
global jQuery object: jQuery
global jQuery object: jQuery16405527471665005403
Output in Safari, Chrome, FireFox, Opera:
global jQuery object: jQuery
Anyone seen something like that? Am I doing something wrong? Is it an expected behavior?
Best regards

An event is added in IE for ajax requests to handle aborting on unload. This is why you see the data expando and it is expected.
Created also a jsFiddle for that: http://jsfiddle.net/agdsX/
