我如何取消一个简单的js调用Ajax而其正在执行？

how can i cancel a simple js ajax call while its being performed?

推荐答案

通常与ajax.abort（）;但在IE上它不会真的辞职请求：

normally with ajax.abort(); but on IE it wont really quit requesting:

调用中止重置对象; onreadystatechange事件处理程序被除去，并且readyState的改变为0（未初始化）。

Calling abort resets the object; the onreadystatechange event handler is removed, and readyState is changed to 0 (uninitialized).

报价是从Microsoft JavaScript的实况。由此我想这在很大程度上取决于浏览器的实现究竟是怎么回事。大多数的浏览器可能会尝试完成正常 - 这样的连接可能仍然达到了一段时间，直到最终收 - 但是那只是一种猜测

the quote is from the Microsoft javascript docu. From this I guess it highly depends on the browser implementation what exactly is going on. most browser will probably try to finish gracefully - thus the connections might still be up for some time until finally closed - but thats just a guess.
