<select name="ctlSelect" id="ctlSelect">
<option value='0' selected="selected">请选择要货运的国家</option>
<option value='0'>----------------------</option>
<option value='224'>United States</option>
<option value='223'>United Kingdom</option>
<option value='199'>Switzerland</option>
<option value='198'>Sweden</option>
</select>

代码如上！ 这个页面为 111.asp
我想把选择的值 提交到这个里面 <form method="POST" action="111.asp?action=<%=("ctlSelect")%>">

点确定 后 该页面地址栏显示111.asp?action=224
红色的部分要怎么写呢

一定要这么做？不能在asp里检查post吗？

一定要这么做的话可以在option的onchange中修改form的action，或者在提交时修改action……

<select name="ctlSelect" id="ctlSelect">
<option value='0' selected="selected">请选择要货运的国家</option>
<option value='0'>----------------------</option>
<option value='United States'>United States</option>
<option value='United Kingdom'>United Kingdom</option>
<option value='Switzerland'>Switzerland</option>
<option value='Sweden'>Sweden</option>
</select>

既然有from表单了就不用跟参数了，直接request就可以了

<form method="POST" action="111.asp?action=<%=("ctlSelect")%>">


<form method="POST" action="111.asp?action=<%=ctlSelect%>">

<script language="javascript">
function ctlSelect_Change(Idx)
{
var selObj=document.ctlSelect;
var selVal=selObj.options[Idx].value;
document.form1.action="111.asp?action="+selVal;
}
</script>
<form name="form1" method="POST" action="111.asp?action=<%=("ctlSelect")%>">
<select name="ctlSelect" onChange="ctlSelect_Change(this.selectedIndex);" >
<option value='0' selected="selected">请选择要货运的国家</option>
<option value='0'>----------------------</option>
<option value='224'>United States</option>
<option value='223'>United Kingdom</option>
<option value='199'>Switzerland</option>
<option value='198'>Sweden</option>
</select>
</form>

6楼的程序运行后显示的是111.asp?action=ctlSelect

你就直接用request.form("ctlSelect")就可以得到select的值了，不过之前得做一下判断。action得到的是什么值。

<script language="javascript">
function ctlSelect_Change(Val)
{
document.form1.action="111.asp?action="+Val;
}
</script>
<form name="form1" method="POST" action="111.asp?action=<%=("ctlSelect")%>">
<select name="ctlSelect" onChange="ctlSelect_Change(this.options[this.selectedIndex].value);" >
<option value='0' selected="selected">请选择要货运的国家</option>
<option value='0'>----------------------</option>
<option value='224'>United States</option>
<option value='223'>United Kingdom</option>
<option value='199'>Switzerland</option>
<option value='198'>Sweden</option>
</select>
</form>
这样呢？
