jQuery的Ajax请求也越来越不取消发送 [英] jQuery Ajax requests are getting cancelled without being sent

问题描述

我试图挂钩脚本微软在全世界的望远镜应用程序。后者侦听端口5050的命令。它是在同一台机器上运行的浏览器（Chrome浏览器的权利，但据我可以告诉的行为是一样的与Firefox 7和IE 9）。

I am trying to hook up a script to Microsoft's World-Wide Telescope app. The latter listens on port 5050 for commands. It is running on the same machine as the browser (Chrome right now, but as far as I can tell the behavior is the same with Firefox 7 and IE 9).

我发送一个访问控制 - 允许 - 产地：*与原来的HTML文件头，以尽量消除XSS限制，我的问题

I am sending a "Access-Control-Allow-Origin: *" header with the original html file to try to eliminate XSS restrictions as my problem.

我的code进入污水处理如下：

My code to access WWT is as follows:

$.ajax({
    type: 'POST',
    url: url,
    data: data,
    crossDomain: true,
    success: success,
    dataType: dataType
});

URL在本例中为http：//127.0.0.1：5050 / layerApi.aspx CMD =新的＆放大器; ......（明明......是速记这里一些额外参数）

url in this case is "http://127.0.0.1:5050/layerApi.aspx?cmd=new&..." (obviously ... is shorthand here for some additional parameters).

看着在Chrome网络诊断，我可以看到这一点：

Looking at the network diagnostics in Chrome, I can see this:

Request URL:http://127.0.0.1:5050/layerApi.aspx?cmd=new&...
Request Headersview source
Accept:application/xml, text/xml, */*; q=0.01
Content-Type:application/x-www-form-urlencoded
Origin:http://gwheeler4
Referer:http://gwheeler4/conceptconnect.html
User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.835.186 Safari/535.1

该请求是走出去 - 我看WWT新建一个图层。但是，我没有得到一个回调。如果我再补充一点被调用错误回调，但jqXHR对象上的error属性仅仅是错误的状态为0。如果我看在Chrome网络请求之我见（取消）的状态，并没有任何反应

The request is going out - I see WWT make a new layer. However, I don't get a callback. If I add an error callback that gets called, but the error property on the jqXHR object is just "error" and status is 0. If I look at the network request in Chrome I see "(cancelled)" as the status and no response.

如果我采取相同的URL，并将其粘贴到新的浏览器选项卡上，我可以看到，响应是预期的XML。

If I take that same URL and paste it in a new browser tab, I can see that the response is the expected XML.

当然，这里不同的是，这是一个GET不是一个职位，但我试过，在我的剧本，并没有什么区别。

Of course, a difference here is that this is a GET not a POST, but I've tried that in my script and it makes no difference.

我是pretty的这个难倒并将AP preciate任何新的想法。

I'm pretty stumped by this and would appreciate any fresh ideas.

推荐答案

如果别人运行到这一点，我们有问题的是，我们在进行从链接Ajax请求，而不是$ P $被pventing链接紧随其后。所以，如果你这样做是在的onclick 属性，确保返回false; 以及

If anyone else runs into this, the issue we had was that we were making the ajax request from a link, and not preventing the link from being followed. So if you are doing this in an onclick attribute, make sure to return false; as well.
