这个问题似乎得到了很多关注，所以以防万一有人想知道，我通过在原始 AJAX 上使用 setTimeout() 解决了这个问题称呼.例如:

This question appears to be getting a lot of views, so just in case anybody was wondering, I solved this problem by using a setTimeout() on the original AJAX call. E.g:

setTimeout(function() {
        ajaxRequest('save_mark','save_mark_completed',[60962,1284,5]) 
    }, 1);

我假设这是 IE 中的某种错误.只需 1 毫秒！

I'm assuming it's some kind of bug in IE. Just 1 millisecond was all it needed!
