未從Azure Blob存儲查詢返回JSON數據

Question

我正在嘗試使用JavaScript和JQuery創建測驗。 我將測驗（問題，選項）的數據存儲在Azure Blob存儲中。

當json本地存儲在同一文件夾中並且我使用getJSON進行調用時，它可以工作。 根據該線程，如果內容位於Azure Blob存儲中，則使用jQuery從Azure Blob存儲中查詢JSON數據將不起作用，但是當我嘗試按照線程中所述進行修改時，我什么也沒得到。 任何幫助是極大的贊賞。 下面，我包含了我的HTML，JSON和JS。

HTML：

<!DOCTYPE HTML>

    <script src="jquery.js"></script>

因此，我通過使用jQuery中的ajax函數來調整我的JS來找到解決方案。 位於此處的解決方案http://blogs.msdn.com/b/tconte/archive/2011/08/10/accessing-windows-azure-blob-storage-using-jquery.aspx使我走上了正確的道路。 我希望這可以幫助其他人。

$.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
});
