推荐答案

如果你有类似的下载链接，它会工作。 />

It would work if you have the Download link something like...

<a id="downloads" style="visibility:hidden;">Downloads Link</a>

演示

了解它是如何工作的。

我看不到代码中有什么问题 - 我假设你得到'正确'警告，但是ID为'下载'的元素没有出现？



首先要检查是的，确实存在一个隐藏下载ID的元素！



我在调试中运行它并检查错误

I don't see anything wrong in the code - I assume you are getting the 'correct' alert but the element with an Id of 'downloads' does not appear?

First thing to check is that there really is an element with an Id of downloads that is invisible!

I'd run it in debug & check for errors

检查并更改prog中的数据类型。

check and change your datatype in prog.
