JSON Azure blob 存储查询未返回数据

Question

我正在尝试使用 JavaScript 和 JQuery 创建测验。我将测验（问题、选项）的数据存储在 Azure blob 存储中。

当 json 本地存储在同一个文件夹中并且我使用 getJSON 进行调用时，它可以工作。根据这个线程，Query JSON data from Azure Blob Storage with jQuery，如果内容在 Azure blob 存储中，那将不起作用，但是当我尝试按照线程中的描述进行修改时，我什么也得不到。任何帮助是极大的赞赏。下面，我包括了我的 HTML、JSON 和 JS。

HTML:

<!DOCTYPE HTML>

    <link href="main.css" rel="stylesheet" type="text/css"/>
    <script src="jquery.js"></script>

所以我通过使用 jQuery 中的 ajax 函数调整我的 JS 找到了解决方案，如下所示。位于此处的解决方案 http://blogs.msdn.com/b/tconte/archive/2011/08/10/accessing-windows-azure-blob-storage-using-jquery.aspx 使我走上了正确的道路。我希望这对其他人有帮助。

$.ajax({
                url: 'https://djmblob.blob.core.windows.net/quizzes/activity.json',
                dataType: 'jsonp',
                jsonpCallback: 'dataCallback',
                success:    function (data) {

    for(i=0;i<data.quizlist.length;i++){ 
        questionBank[i]=new Array;
        questionBank[i][0]=data.quizlist[i].question;
        questionBank[i][1]=data.quizlist[i].option1;
        questionBank[i][2]=data.quizlist[i].option2;
        questionBank[i][3]=data.quizlist[i].option3;
    }
     numberOfQuestions=questionBank.length; 


    displayQuestion();
    }//gtjson
});
