问题：jQuery控件的一个BUG 使用$.ajax时出现的错误，IE7下才会出错，IE6,IE8都正常。错误提示如下图： 官方论坛上的说明： http://forum.jquery.com/topic/object-doesn-t-support-this-property-or-method-from-jquery-1-4-1-in-ie7-onlyhttp://dev.jquery.com/ticket/6498http://dev.jquery.com/ticket/6314解决方案：修改jquery-1.4.2.js。 论坛上有人提出的修改方式，我测试过可行。复制代码 代码如下: 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.
