IE6中的jQuery JSONP问题

我在使用IE6从不同域中的服务器检索JSONP响应时遇到了问题。IE6中的jQuery JSONP问题

当我使用JSONP向与网页相同域中的服务器进行相同的AJAX调用时，在所有浏览器（包括IE6）中都一切顺利。但是，当我使用JSONP在域（XSS）之间进行呼叫时，Internet Explorer 6会锁定。具体来说，CPU高达100％，并且“成功”回调从未达到。我唯一一次在域之间取得成功的时候是响应非常短（通常少于150字节）。答复的长度似乎很重要。

我正在使用jQuery 1.2.6。我试过$ .getJSON（）方法和$ .ajax（dataType：“jsonp”）方法，但没有成功。这在FF3和IE7中运行的很好。我一直无法找到有类似问题的其他人。我认为这种类型的功能在IE6中完全由jQuery支持。

任何帮助是非常赞赏，

这里是为了使AJAX调用 html页面的代码。制作这个文件（和jQuery库）的本地副本，并使用IE6进行拍摄。对我而言，它总是会导致CPU在没有响应的情况下出现尖峰。

    { 
     var dataSourceUrl = "http://code.katzenbach.com/Default.aspx?callback=?"; 
     $.getJSON(dataSourceUrl, {c: count, test: "true", nt: new Date().getTime()}, function(results) { 
       var response = new String(); 
       response += "<div>"; 
       for(i in results) 
       { 
        response += results[i]; 
        response += " "; 

       } 
       response += "</div>"; 
       $("#" + targetId).html(response); 
     }); 
    }

以下是响应中返回的JSON。根据JSLint，它是有效的JSON（一旦你移除了围绕它的方法调用）。真正的结果会有所不同，但这似乎是最简单的例子，会导致失败。服务器是一个返回类型为“application/json”的响应的ASP.Net应用程序。我已经尝试将响应类型更改为'application/javascript'和'application/x-javascript'，但它没有任何影响。我非常感谢帮助。
