如何用VBScript操作Options ?
在ASP页面中，如何用VBScript去操作Html的select表单元素？？

下面是我写的，可是总报错：

document.form1.sDate.length=0
for i=nStartDay to nDays
document.form1.sDate.options.add i,i
next
提示“类型不匹配”

document.form1.sDate.length=cint(nDays-nStartDay+1)
for i=nStartDay to nDays
document.form1.sDate.options(i).value=i
document.form1.sDate.options(i).text=i
next
提示“缺少对象：document.form1.sDate.options(...)”

请高手们指导一下。谢谢

[解决办法]
<form name= "form1 " id= "form1 ">
<select name= "sDate "> </select>
</form>
<script language= "vbscript ">
Dim o,i
For i=1 To 12
Set o=Document.createElement( "OPTION ")
o.value=i
o.text=i
Document.form1.sDate.add o
Next
</script>
