javascript - 为什么 RSS 脚本无法加载？ jQuery

Question

我有这个代码:

<script src="http://code.jquery.com/jquery-2.2.2.min.js"></script>
<!-- start feedwind code -->
<!-- select protocol http or https -->
<script type="text/javascript"> 
$.holdReady(true);
$.getScript("http://feed.mikle.com/js/rssmikle.js", 
function() { $.holdReady(false); });
console.log( "Load was performed." );
</script>

<!--<script type="text/javascript" src="http://feed.mikle.com/js/rssmikle.js"></script>-->
<script type="text/javascript">

<!-- end feedwind code --><!--  end  feedwind code -->

它应该从 mikle.com 加载 RSS，这样您就应该看到帖子列表。我想使用 Jquery 加载脚本。我用了 $.holdReady(true);所以函数 feedwind_show_widget_iframe(params);下载脚本之前不应调用。我还在控制台中看到文件已加载，然后函数被调用的日志。如果我用 Mikel 的 RSS 取消注释脚本标记，那么一切都会正常，但我想动态加载它。

当您调用getScript时您向其传递一个回调( function() { $.holdReady(false); } )，以便在脚本加载后执行。

您已放置依赖于该脚本的代码，以便它在您开始请求脚本后立即运行，而不是在脚本可用后运行的回调中运行。
