用vbs在网页每20秒点击一下元素
您可以使用下面的代码来实现：
Set objIE = CreateObject("InternetExplorer.Application")
objIE.Visible = True
objIE.Navigate "http://www.example.com"
Do While objIE.ReadyState <> 4
WScript.Sleep 20000 'Wait 20 seconds before clicking the element
Set elements = objIE.Document.getElementsByTagName("input")
For Each element In elements
If element.Type = "submit" Then 'Check if the element is a submit button and click it
element.Click()
End If
Next Loop
