<select name="bighy">
<option value="" selected>请选择</option>
<option value="1">不限</option>
<option value="2">不限</option>

改正:
<select name="bighy" onchange="form1.hiddenfield.value=this.options[this.selectedIndex].value">
<option value=333>aa
<option value=444>bb
<option value=555>cc
</select>

<option value=333>aa
<option value=444>bb
<option value=555>cc
</select>

request("bighy")就得到value值了。
不知道你说的id是什么意思。

asp:

response.write tmp

<%
tmp=request.form("bighy")
response.write tmp
%>

如果这样不行的话可以写一个函数对当前业面的一个hidden域赋值为选定的id
<form name="form1" method="post" action="2.asp">
<select name="bighy" onchange="form1.hiddenfield.value=this.options[selectedIndex.value">
<option value=333>
<option value=444>
<option value=555>
</select>
<input type="hidden" name="hiddenfield">
</form>
2.asp中request.form("hiddenfield")
<form name="form1" method="post" action="2.asp">
<select name="bighy" onchange="form1.hiddenfield.value=this.options[selectedIndex.value">
<option value=333>
<option value=444>
<option value=555>
</select>
<input type="hidden" name="hiddenfield">
</form>
2.asp中request.form("hiddenfield")

你要在客戶端嗎?
<form name=form>
<select name=bighy onchange="javascript:check()">
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
</select>
<script language="JavaScript">
<!--
function check()
{
var url = form.bighy.options[form.bighy.selectedIndex].value;
alert (url);
}
// -->
</script>
</form>
<form name=form>
<select name=bighy onchange="javascript:check()">
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
</select>
<script language="JavaScript">
<!--
function check()
{
var url = form.bighy.options[form.bighy.selectedIndex].value;
alert (url);
}

</form>
