<script language=JavaScript>
function passvalue(){
for(var i=0;i <document.testdata.testvalue.options.length;i++)
{
if (document.testdata.testvalue.options[i].selected==true)
{
document.testdata.inputdata.value=document.testdata.testvalue.options[i].value;
}
}
}
</script>
<BODY>
<form name= "testdata ">
<select name= "testvalue " onchange= "passvalue() ">
<option value=1> test1 </option>
<option value=2> test2 </option>
<option value=3> test3 </option>
</select>
<input type=text name= "inputdata ">
</form>
</BODY>
</HTML>
用onchange不会刷新啊

<%
String name2 = request.getParameter( "name ");
if(name2 != null && ! " ".equals(name2))
{
do something for name2
}
%>
<form name= "formname " method= "post " action= "***.jsp " >
<table align= "center " border= "0 " cellpadding= "0 " cellspacing= "1 " >
<tr>
<td> 姓名：
