为什么ajax调用会使IE11和CSS动画冻结？

Question

这个ajax调用会使IE11和CSS动画冻结，但在Mozilla和Chrome中却都运行正常。到目前为止，我尝试了以下几种解决方法：

1、禁用缓存：我从服务器禁用了它；

2、尝试过setTimeout技巧；

3、删除了嵌套函数，导致 .html()方法无法单独运行。

$.ajax({type: 'POST',
        url: "accordion.php?cat="+aid,
        async: true,
        success: function (html) {
                $("#accordion").animate({ right: "140%"},500, function () {
                  $(this).css("right","-25%", $(this).hide(1, function() {
                    $(this).html(html).show(1, function() {
                      $(this).animate({right: "100%"},1000),$ajaxloading.fadeOut("slow")})}));});}})

I found the problem. The problem is Active Content filtering feature of IE. My php includes script resources linked to .js files. During the writing of php, IE hangs when it comes to those lines. It is a Jquery accordion and needs several js'es to operate. I deleted script tags and was working fine. I think I'll move those tag to main page and they will be loaded and run always even they are not needed; which is not my first preference.
