IE浏览器替代window.stop（）（取消所有待处理的请求） [英] IE alternative to window.stop() (cancel all pending requests)

问题描述

我正在寻找一个替代window.stop（）的IE浏览器。我曾尝试document.execCommand（停止），但它似乎并没有工作。我想取消它是从我使用ASP的用户控件中称为XMLHtt prequest。我不能使用jQuery的.abort（），因为我没有设置要求我自己。

I'm looking for an alternative to window.stop() for IE. I have tried document.execCommand('Stop'), but it doesn't seem to work. I'm trying to cancel a XMLHttpRequest which is called from within a ASP user control i'm using. I can't use jQuery's .abort() since i do not set the request my self.

推荐答案

我想在页面上控制使用jQuery.ajax，你知道，当你需要中止请求，根据您的标准。

I assume control on the page uses jQuery.ajax and you know when you need to abort the request, under your criteria.

怎么这样呢？

(function ($) {
    var xhr = null, 
        originalAjax = $.ajax,
        updatedAjax = function (url, options) {
            xhr = originalAjax(url, options);
        };
    $.ajax = updatedAjax;
})(jQuery);

现在你有一个变量叫做XHR持有标的XMLHTTP对象。当你需要，你可以拨打中止（）的对象。

Now you have a variable called xhr which holds the underlying xmlhttp object. You can call abort() on the object when you need to.

在画背面是该变量将被填充每个Ajax请求的jQuery做的，我只包括特定页面上的这个脚本，甚至重置AJAX当你完成。

The draw back is that variable will be populated for each ajax request done by jQuery, and I would only include this script on that particular page, maybe even reset the ajax when you are done.

我没试过，只是一个想法，因为我一直在嘲弄Ajax调用所有的时间。或许有人会认为，这种做法是有点激烈！

I haven't tried this, just an idea, as I have been mocking ajax calls all the time. Some might think that this approach is a little bit drastic!

希望你觉得它有用。
