外行一枚，还请大神指点。
我需要到一个网页上下载数据文件。网页布局如下：
需要点击的按钮代码如下：
我通过这样的指令试图点击：
没有提示任何错误，但是页面也没有任何反应。
如果手动点击Download会提示文件下载：
如果持续点击会出现这样的报错：
我大概知道这个是因为这个网页一直在自动刷新，所以提示了错误。
==========================================================================
我的问题是：
1、为什么第一次执行的时候页面没有任何反应？
2、面对这种因为刷新提示的错误，有怎样的解决方案？
==========================================================================
网页完整代码附在下方。
谢谢！?
