XDomainRequest中止POST在IE 9 [英] XDomainRequest aborts POST on IE 9

问题描述

我做跨域Ajax调用。

I am doing a cross domain Ajax call.

我的code：

if (window.XDomainRequest) // Check whether the browser supports XDR.
{
    xdr = new XDomainRequest(); // Create a new XDR object.
    if (xdr) {
        xdr.timeout = 3000;//Set the timeout time to  3 second.
        xdr.onload = function () {
            alert("Success");
        };
        xdr.onerror = function () {
            alert("Error");
        };
        xdr.ontimeout = function () {
            alert("Error");
        };
        xdr.open("post", urlSearch);
        xdr.send();
    }
}
else {
    $.ajax({
        url: urlSearch,
        type: 'POST',
        dataType: 'json',
        timeout: 3000,
        success: function (data) {
            alert("Success");
        },
        error: function () {
            alert("Error");
        }
    });
}

以上code正常工作在所有的浏览器，但在IE有时它显示类似的错误（中止）。

The above code works fine in all browsers, but in IE sometimes it is showing an error like (aborted).

要克服这种错误我搜索的谷歌并没有找到什么好的解决办法。

To overcome this error I searched in Google and did not find any good solution.

您可以看到（中止）是显示错误消息。 http://postimg.org/image/k01u6t9v5/

You can see the error message where (aborted) is showing. http://postimg.org/image/k01u6t9v5/

当我这样做单独的呼叫到一个特定的URL时，它没有显示任何（中止）消息（显示出成功的警报）。但是，当我做多个呼叫（如图像），它表明类型的错误。

When I do individual call to a specific URL it is not showing any (aborted) message(Showing Success alert). But when I do multiple call (like in the image) its showing that type of error.

如何解决这个问题？

请帮忙

在此先感谢

推荐答案

我不知道这是同样的问题，但对我来说所有这些需要设置：onError的; onprogress; ontimeout;和onload事件。这里有一些参考的讨论这个问题：

I'm not sure this is the same problem, but in my case all of these needed to be set: onerror; onprogress; ontimeout; and onload. Here are some references that discuss the problem:

有一些其他的方面。他们是分散的，有时在他们的建议解决矛盾的。例如，一种建议包裹xdr.send呼叫中一个的setTimeout

There are many others as well. They're scattered and sometimes contradictory in their suggested solution. For example, one suggests wrapping the xdr.send call in a setTimeout.

我所看到的行为走了为每个事件处理函数添加非空机构。我不知道如果所有都是必要的。该setTimeout的包装肯定的没有的必要。

The behavior I was seeing went away by adding non-blank bodies for each of the event handler functions. I'm not sure if all are necessary. The setTimeout wrapper was definitely not necessary.

一个可能无关紧要一块信息：在我的情况，我决定每一个处理程序绑定到这个对象。我还添加了功能的实现，以保持我的编译器从它们分配到同一个空函数。我的code的使用GET，POST没有。情况因人而异。

One possibly irrelevant piece of info: in my case I decided to bind each handler to the 'this' object. I also added function implementations to keep my compiler from assigning them all to the same empty function. My code was using GET, not POST. YMMV.

您code留下一个处理程序取消设置：

Your code leaves one handler unset:

if (window.XDomainRequest) // Check whether the browser supports XDR.
{
    xdr = new XDomainRequest(); // Create a new XDR object.
    if (xdr) {
        xdr.timeout = 3000;//Set the timeout time to  3 second.
        xdr.onload = function () {
            alert("Success");
        };
        xdr.onerror = function () {
            alert("Error");
        };
        xdr.ontimeout = function () {
            alert("Error");
        };
        // this also needs to be set
        xdr.onprogress = function() {
            window.console.log('progress');
        };
        xdr.open("post", urlSearch);
        xdr.send();
    }
}
else {
    $.ajax({
        url: urlSearch,
        type: 'POST',
        dataType: 'json',
        timeout: 3000,
        success: function (data) {
            alert("Success");
        },
        error: function () {
            alert("Error");
        }
    });
}
