如何修改我没有具体ID ID的代码？在vbscript中

Question

我有这个代码进入网站并使用vbs登录：

Set IE = CreateObject("InternetExplorer.Application")   
 IE.Visible = 1   
 IE.navigate "http://www.mcmconsultores.com.br/arearestrita/Account/Login"   
 Do While (IE.Busy)   
     WScript.Sleep 10   
 Loop   
 Set Helem = IE.document.getElementByID("TXTEmailLogin")   
 Helem.Value = "blabla@something.com.br" ' change this to yours   
 Set Helem = IE.document.getElementByID("password")   
 Helem.Value = "ladkask" ' change this to yours   
 Set Helem = IE.document.Forms(2)   
 Helem.Submit   

因此，在网站上我没有密码ID或最终点击提交，我该如何使用？
