Question

vbs中代码getelementById和vbelementsbyname?

vbs中代码

Set ie = CreateObject("InternetExplorer.Application")

Dim ss
ss = "123456"
ie.visible = True
ie.navigate "http://www.baidu.com/"
While ie.busy Or ie.readystate <> 4
Wend
ie.document.getElementbyid("kw").value = ss
ie.document.getElementById("su").click
Set ie = Nothing

可以执行，而代码
Set ie = CreateObject("InternetExplorer.Application")
Dim ss
ss = "123456"
ie.visible = True
ie.navigate "http://www.baidu.com/"
While ie.busy Or ie.readystate <> 4
Wend
ie.document.getElementsByName("wd").value = ss
ie.document.getElementById("su").click
Set ie = Nothing
却报错？

Answer 1

ie.document.getElementsByName("wd").value = ss
改成
ie.document.getElementsByName("wd")(0).value = ss

getElementsByName返回的是一个标签对象的集合，

Answer 2

是给元素定义时给它加了ID或者NAME属性，这两个区别就是按ID或者是NAME去抓取元素。
