本地文件发送jQuery AJAX GET，成功，但数据未定义

我在本地html文件中编写了一个简单的代码来测试jQuery AJAX，如下所示：

$(document).ready(function(){
    $.ajax({
      url: "http://hqdigi2.eastmoney.com/EM_Quote2010NumericApplication/CompatiblePage.aspx?Type=Z2&r=1386912455181&fav=300251",
      dataType: "script",
      dataFilter: function(data, type) {
        console.log("### type: " + type+", data: " + data);
      },
      success: function(data, status, xhr) {
        console.log("****success: " + data + ", status: " + status);
        console.log("xhr.responseText: " + xhr.responseText);
      },
      error: function(jqXhr, status, err) {
        console.log("!!!!Error - xhr:" + jqXhr + ", status: " + status + ", " + err);
      }
    });
});

var stockData={DataList:["2,300251,aStockName,41.64,1.19%,0.49,41.57,0,41.64,0,160955,66550,41.30,41.15,42.15,40.38,1,198,0"],UpDatetime:"2013-12-16 14:48:27"};

执行后，控制台显示：

Resource interpreted as Script but transferred with MIME type text/html: "http://hqdigi2.eastmoney.com/EM_Quote2010NumericApplication/CompatiblePage.aspx?Type=Z2&r=1386912455181&fav=300251&_=1387173844186". 
### type: script text, data: undefined 
****success: undefined, status: success 
xhr.responseText: undefined

但回复如下所示：

$(document).ready(function(){
    $.ajax({
      url: "http://hqdigi2.eastmoney.com/EM_Quote2010NumericApplication/CompatiblePage.aspx?Type=Z2&r=1386912455181&fav=300251",
      dataType: "script",
      dataFilter: function(data, type) {
        console.log("### type: " + type+", data: " + data);
      },
      success: function(data, status, xhr) {
        console.log("****success: " + data + ", status: " + status);
        console.log("xhr.responseText: " + xhr.responseText);
      },
      error: function(jqXhr, status, err) {
        console.log("!!!!Error - xhr:" + jqXhr + ", status: " + status + ", " + err);
      }
    });
});

var stockData={DataList:["2,300251,aStockName,41.64,1.19%,0.49,41.57,0,41.64,0,160955,66550,41.30,41.15,42.15,40.38,1,198,0"],UpDatetime:"2013-12-16 14:48:27"};

我如何获得此回复文本

我还试图将数据类型更改为“text”，但Chrome抱怨访问控制Allow Origin不允许Origin null。我不想禁用Chrome的安全设置以允许本地文件跨域访问

很抱歉格式不好，因为我的网络问题，cdn.sstatic.net上丢失了一些css/js文件

我尝试了一次又一次，最后我发现我可以从成功回调中获得响应对象stockData！数据类型设置为“script”（或使用$.getScript）。 我还不明白的是，只有数据类型的脚本和jsonp才能得到响应，文本、json或html将被远程域访问错误阻止
