Jquery Ajax BUG: object doesn "T support this property or Method

Problem: a bug in the jquery Control
When $. Ajax is used, an error occurs only in IE7. IE6 and IE8 are normal. The error message is as follows:

Description on the official forum:

Http://forum.jquery.com/topic/object-doesn-t-support-this-property-or-method-from-jquery-1-4-1-in-ie7-only
Http://dev.jquery.com/ticket/6498
Http://dev.jquery.com/ticket/6314

Solution:
Modify jquery-1.4.2.js.

I have tested the modification method proposed on the forum.

CopyCode The Code is as follows: Hi, I found this seems to relate to jquery bug 6314 (http://dev.jquery.com/ticket/6314 ). in IE7, if "Enable Native XMLHttp Support" is checked (under tools> Internet Options> Advanced Tab> inside the Security Section) then this error shows up. unchecking/disabiling the option seems to resolve the error.

However, since I cannot tell all website viewers to uncheck that option, then the following code also seems to resolve the issue:
In non-minified jquery, find the lines:
Try {
VaR oldabort = xhr. Abort;
Xhr. Abort = function (){
If (xhr ){
Oldabort. Call (xhr );
}

Onreadystatechange ("Abort ");
};
} Catch (e ){}

Replace it with the following code:
Try {
VaR oldabort = xhr. Abort;
Xhr. Abort = function (){
If (xhr ){
If (oldabort. Call === undefined ){
Oldabort ();
} Else {
Oldabort. Call (xhr );
}
}

Onreadystatechange ("Abort ");
};
} Catch (e ){}

I believe the issue is as stated by other users in this forum, that the xhr (XMLHTTP) object is a native IE Object, so the abort function on the xhr. abort function does not support call.
