选择文件后，YUI上传挂起

Question

下面是我从包含锐上传用户控制整个代码。是否有什么我失踪。现在，当我通过Firebug的JavaScript代码步骤，它挂在上传（）函数的第一行。我有一个处理文件的ashx的第一行设置一个断点，但它永远不会被调用。因此，它不会走到这一步。我想，我只是失去了一些东西愚蠢。我用这个控制很多次没有问题了。我使用所有的CSS文件和样品中的YUI下载提供的文件夹图形。

如果我没有错过什么，有没有调试运行这个问题，然后通过通过与萤火虫的JavaScript步进更全面的方式。我试着打开日志记录YUI和关闭，并永远不会得到任何日志的任何地方。我不知道现在在哪里去了。

似乎没有在进度变量名的情况下，不匹配：您是指它作为进度其他地方，但进度在上传（）函数

。

这是更大的问题是，你定义onFileSelect函数内部的进度变量。由于这个原因，可变范围有限，并且不应该是可访问的任何其他地方。

看移动的进度定义出来的有（或新鲜的来自世界各地的它的使用使用的getElementById的DOM抓住它）和固定的情况下，不匹配解决您的问题。

YUI 2.8与事件和上载的问题。它不会工作，除非你使用2.9事件并上传。我浪费了比我不想承认试图让2.8工作更多的时间。我希望这可以节省有人的时间。
