EasyXDM ErrorHandler 仅在 Firefox 上执行两次

我使用 easyXDM 发出跨域 POST 请求并接收响应。当请求超时时，当我在 Firefox 上运行 easyXDM 时，easyXDM 会执行 ErrorHandler 函数两次。在 Chrome 和 IE7 上它运行良好（即仅执行一次）。这是为什么？有什么想法可以预防吗？

Firefox 版本 6.0.2

EasyXDM 版本 2.4.15.118

托管在 IIS 上

示例代码（这在我的计算机上按上述方式工作，“错误”警报在 Firefox 上出现两次，在 Chrome 和 IE7 上出现一次）：（显然，超时设置为低，所以它总是会发生）

<html>
<head>

<script type="text/javascript" src="easyXDM.js"></script>
<script type="text/javascript">

    var rpc = new easyXDM.Rpc({
          remote: "http://myserver.com/Cors.html"
        }, {
          remote: {
            request: {}
          }
      });

    request = {
        url: "http://myserver.com/DoSomething.aspx",
        method: "POST",
        timeout: 1,
        data: {
            SomeData: "SomeInformation"
        }
    };

    var responseHandler = function(response) {
        alert("Responded");
    };

    var errorHandler = function(error) {
        alert("Error");
    };

    rpc.request(request, responseHandler, errorHandler);

</script>

</head>
<body>
</body>

原文

I use easyXDM to make cross-domain POST request and receive a response. When the request reaches a timeout, easyXDM executes the ErrorHandler function twice when I run it on Firefox. On Chrome and IE7 it works fine (i.e. just one execution). Why is that? Any ideas how can I prevent it?

Firefox version 6.0.2

EasyXDM version 2.4.15.118

Hosted on IIS

Example code (this works as described above on my computer, the "Error" alert appears twice on Firefox and once on Chrome and IE7): (obviously, the timeout is set so low so that it would always happen)

<html>
<head>

<script type="text/javascript" src="easyXDM.js"></script>
<script type="text/javascript">

    var rpc = new easyXDM.Rpc({
          remote: "http://myserver.com/Cors.html"
        }, {
          remote: {
            request: {}
          }
      });

    request = {
        url: "http://myserver.com/DoSomething.aspx",
        method: "POST",
        timeout: 1,
        data: {
            SomeData: "SomeInformation"
        }
    };

    var responseHandler = function(response) {
        alert("Responded");
    };

    var errorHandler = function(error) {
        alert("Error");
    };

    rpc.request(request, responseHandler, errorHandler);

</script>
