ASP如何获取JS值

mjch2008 2009-08-26 09:50:41

首先：下拉框触发onchange="aa(this)"
<select name="SmallClassName" onchange="aa(this)">
<option value="9">哈哈</option>
</select>

然后在JS代码中：
function aa(str)
{
<%

SQL="select * from KS_smallclass where id="&sid&""
rs.open exec,conn,1,1
%>
document.getElementById("aa").innerHTML="<%=rs("c1name")%>： <input name='cailiao1' type='file' id='cailiao1' />";

<script>

function aa(sel){

  var n = sel.options[sel.selectedIndex].value;

  hf.location.href= "test1.asp?n=" + escape(n) + "&" + escape(new Date())

}

</script>

<select name="SmallClassName" onchange="aa(this)">                  

      <option value="9">哈哈</option>

      <option value="2">哈哈</option>                

</select>

<div id="pad"></div>

<iframe name="hf" style="display:none"></iframe>

test1.asp



<%

s_id = Trim(Request("n"))



'查数据库略

SQL="select * from KS_smallclass where id=" & s_id

'rs.open sql, conn,1,1 

s = ""

For i = 1 To s_id

	s = s & "<input name='cailiao1' type='file' id='cailiao1' />"

Next



s = Replace(s, """","\""")

%>

<script>

window.onload=function(){

	parent.document.getElementById("pad").innerHTML = "<%=s%>";

	location.replace("about:blank")

}

</script>
