Could not complete the operation due to error 80020101

Question

I am running an ExtJS 4.1 application. It is running just fine in FireFox, but I get this error in Internet Explorer 8: Could not complete the operation due to error 80020101.

I have found various possible fixes, but none seemed to fit my needs.

How can I make the application work in IE8?

@RobW I do not know where the problem lies. My application is pretty heavy on JavaScript(mainly because of the ExtJS framework) and the errors in IE8 are not helping at all. I have no idea on how should I find the source of the problem. I am hoping that someone else has faced this issue too(or anything similar). — Dragos, Jul 02 '12 at 14:05
Well, it can be narrowed down. 80020101 is an AJAX error, for example this: http://stackoverflow.com/a/10275316/1204258 — Andrew Leach, Jul 02 '12 at 14:48
@AndrewLeach Thank you for the link! That was helpful: there was a comma after some ajax parameters, as suggested in that answer. Please write an answer so I can accept it(it wouldn't seem fair to write one myself, since it was your suggestion that helped). — Dragos, Jul 03 '12 at 12:16

Error 80020101 is an AJAX error, so there are a number of potential issues to investigate. A useful starting point might be a prior SO question https://stackoverflow.com/a/10275316/1204258 which deals with trailing commas in object definitions.

I got the same error in an included js file. it appeared only in IE.

the problem was because of missing </script> tag at the end of include file.

Had the same non-foundable error on IE9.

There was an AJAX request transfering a ....

Solved the error with this:

<script type="text/javascript">
    //<![CDATA[

    ... code goes here ...

    //]]>
</script>

Same thing was happening to me while using ExtJS to "require" modular javascript code. The reason: I included the "extends" keyword by mistake, which is reserved in IE8. Make sure you're not using any reserved keywords as your attribute keys without putting them in quotes first.

I got the same issue in IE, the problem was the html comment used in the javascript Replaced the html comment with javascript comment, then it's works fine for me.
