我尝试实现等待元素可用(在Stackoverflow本身中找到)但收到错误:
运行时错误'-2147467259(80004005)':
自动化错误
未指定错误
以下是代码段:
Do
Set testObject = Nothing
On Error Resume Next
Set testObject = html.getElementById("j_username")
On Error GoTo 0
DoEvents
Loop While testObject Is Nothing
答案 0 :(得分:0)
您收到错误,因为HTML文档尚未完全加载。在你的do循环中添加:
Do Until IE.ReadyState = READYSTATE_COMPLETE
DoEvents
Loop
Set html = IE.Document
只有在正确引用加载的对象后才有意义:
Set testObject = html.getElementById("j_username")
