在這之前有介紹過jquery1.4.1的jquery abort bug，見：https://www.aiwalls.com/kf/201203/124315.html ，就是說在IE7下無法執行請求的abort操作。
沒想到1.4.3版本瞭還是沒有修復！
他的註解更可惡：
1. // Override the abort handler, if we can (IE 6 doesn't allow it, but that's OK)
2. // Opera doesn't fire onreadystatechange at all on abort
3. try {
4. var oldAbort = xhr.abort;
5. xhr.abort = function () {
6. // xhr.abort in IE7 is not a native JS function
7. // and does not have a call property
8. if (xhr && oldAbort.call) {
9. oldAbort.call(xhr);
10. }
11.
12. onreadystatechange("abort");
13. };
14. } catch (abortError) { }
修復方法同之前：有需要可查看：/kf/201203/124315.html
