为什么我不能用VBA访问这个popup框的内容？
这里是popup框的html：

我自己的代码：
Set uploadForm = ieUpload.document.getElementById("uploadForm") For Each inputTag In uploadForm.getElementsByTagName("input") If inputTag.Name = "contentIndexed[0]" Then inputTag.Click Next inputTag
VBA在for循环中引发“对象variables或块variables未设置”错误。
在聊天讨论后编辑
原来这个文件还没有完成加载。 检查ieUpload.Busy伎俩。 例如，看这个问题 ，它在DoEvents循环中检查Busy 。
原始答案
首先：
- 确保你的源文件的顶部有
Option Explicit。 - 确保你已经添加了对象引用到你正在使用的HTML库。 除非没有别的select，否则不要使用
CreateObject！ - 确保你已经使用
Dim来给所有的variables赋予一个特定的types – 不是Variant或Object。
现在，假设你正在使用MSHTML ，没有函数document.get Elements ById 。 你想要什么是Element ById ，没有“元素”上的“s”。 通过代码单步骤 – 我怀疑uploadForm Nothing时，你点击For循环，所以uploadForm.getElementsByTagName是引发错误。
编辑为什么我提到添加上面的参考？ 因为如果你已经添加了引用，并且你已经说Dim uploadForm as MSHTML.IHTMLElement2 ，那么VBA编辑器会自动将案例更改为uploadForm.getElementsByTagName 。 既然它没有，我想你没有Dim的地方，或者它不是一个具体的Dim 。
（当然，除非你创build了一个名为getelementsbytagname的variables，你不应该这么做:)）
