Javascript 此函数未显示结果

我编写了以下函数来获取一些

RSS

feed数据

这很有趣，因为脚本末尾的两个警报都会显示，但结果不会通过

jQuery:：append（）

附加到它的div，我必须提到，传递给append函数的ID是完全正确的

    function generateTopNews() {
        // Manage RSS url

对于（变量i=0；i

因为ajax是异步的，所以应该在成功事件中为

append（）

编写代码。否则，

append（）

将在从服务器获取数据之前发生

function generateTopNews() {
      // Manage RSS url
      var targetsURLs = new Array("http://www.jamejamonline.ir/rssfeed?code=01-10-95", "http://www.khorasannews.com/RSS.aspx?type=1", "http://www.tabnak.ir/fa/rss/1", "http://www.varzesh3.com/rss/");

      // Temp variables
      var resultArray = new Array();
      var rssCounter = 0;
      // RSS Loader

          $.ajax({
              url: "http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=" + encodeURIComponent(targetsURLs[i]),
              dataType: "json",
              success: function (data) {
                  var fetchedFeed = data.responseData.feed.entries;

您已经采取了哪些步骤来调试页面？你发现问题了吗？不那么请尽你所能，不要让别人帮你调试。@Andrey我已经调试过了，我只是不知道为什么附加函数不打印任何东西！如果将断点/console.log放在

append

和resultArray的填充行之前，您将很快发现问题。
