分享兄弟们，救救小弟，关于jsp的select 框的问题，如解决不成就要通宵了！
怎样不选select框内容， 直接点击button把select框中的所有值带过去？？？
代码摘要如下：可直接运行。
<%@ page import="java.util.*"%>
<script language=javascript>
function dosub(form)
{
if (confirm("Are you sure to change this ReportsTo?")) {
form.AtAction.value = "SaveData";
alert("hello==>"+form.hello.options.length);
form.submit();
return true;
}
return false;
}
</script>
<html>
<title>test</title>
<body>
<FORM NAME="changerep" action="test.jsp" METHOD="POST">
<TABLE WIDTH=100% CELLPADDING=3 CELLSPACING=0 BORDER=0>
<tr valign=top><td>
<table width=100% height=100% border=0>
<tr valign=top>
<td align=center>
Sales Manager:<br>
<%
String AtAction = "";
if (request.getParameter("AtAction")!=null)
AtAction = request.getParameter("AtAction");
System.out.println("AtAction==>"+AtAction);
if(AtAction.equals("SaveData"))
{
String strH[] = request.getParameterValues("hello");
out.println("<hr>==>"+strH);//值没过来
}
%>
</td></tr>
<tr><td align=center>
<input type=button name="dochange" value="Apply" onclick="dosub(document.changerep)">
</td></tr>
</table>
</td><td align=center>

其实这种做法效率是非常低的，最好的方法是声明个类， 用session 方式把类带过去。

当然试过了， 因为， select 框，只有在选中的情况下，才能把值带过去。

你只改了javascript代码就搞定了吗?jsp没改吗?我试了一下，只有循环打印，才会出现你期望的结果。

兄弟们， 问题解决了， 但是办法很土， 代码如下：
function dosub(form)
{
if (confirm("Are you sure to change this ReportsTo?"))
{
form.AtAction.value = "SaveData";
alert("hello==>"+form.hello.options.length);
for (i=0;i<form.hello.options.length;i++)
form.hello.options[i].selected = true;
form.submit();
return true;
}
return false;
}
function dosub(form)
{
if (confirm("Are you sure to change this ReportsTo?"))
{
form.AtAction.value = "SaveData";
alert("hello==>"+form.hello.options.length);
for (i=0;i<form.hello.options.length;i++)
form.hello.options[i].selected = true;
form.submit();
return true;
}
return false;
}
