Function Main
Set IE = WScript.CreateObject("InternetExplorer.Application", "IE_")
IE.Visible = True

Wait IE
WScript.Echo "This is WSH version", WScript.Version
With IE.Document
.getElementByID("username").value = "myuser"
.getElementByID("password").value = "mypass"
.getElementByID("top").submitAction
End With
End Function
Sub Wait(IE)
Do
WScript.Sleep 500
Loop While IE.ReadyState < 4 And IE.Busy
Do
WScript.Sleep 500
Loop While IE.ReadyState < 4 And IE.Busy
End Sub
Sub IE_OnQuit

<p>As a general rule,
traffic on wireless networks, including AirRowdy, is <i><b>not</b></i> encrypted. This means there is a risk of
having your session "sniffed" during transmission. If you plan
on entering sensitive information (passwords, credit card numbers)
on a website, ensure the site is SSL-encrypted - the URL
should start with http<strong><i>s</i></strong> (not http) and
you should see a "lock" icon in your browser's status
bar.</p>

推荐答案
我不确定表单元素是否有成员名为 submitAction 的方法。应该只是？
I'm not sure a form element has a member method called submitAction. Should it be simply submit?
我没有看到任何包含您要查找的ID的元素：username，密码或top
And I don't see any elements with the IDs you're looking for: "username", "password" or "top"
With IE.Document
.getElementByID("username").value = "myuser"
.getElementByID("password").value = "mypass"
.getElementByID("top").submitAction
End With
I猜猜你正在寻找例如
I'm guessing you're looking for eg
<td width="31%"><input type="text" maxlength=63 size=25 name=username /></td>
您可以使用，返回元素数组
where you would use getElementsByName, which returns an array of elements
dim elements: set elements = document.getElementsByName("username")
elements(0).Value = "username"
