JSP

父页：send_message.jsp

<script language=javascript type="">
//open win
function g_OpenWindow(pageURL, innerWidth, innerHeight)
{
var ScreenWidth=screen.availWidth
var ScreenHeight=screen.availHeight
var StartX=(ScreenWidth-innerWidth)/2
var StartY=(ScreenHeight-innerHeight)/2
var wins=window.open(pageURL,'OpenWin','left='+StartX+',top='+StartY+',Width='+innerWidth+',height='+innerHeight+',resizable=yes,scrollbars=yes,status=no,toolbar=no,menubar=no,location=no')
wins.focus();
}
</script>

<body>
<table width=90% cellpadding="1" cellspacing="1" align="center">
<tr><td colspan=4 align="left" class="td1">      
<font color="#2E75BB"><b>NCSB站内邮件系统</b></font><p></td></tr>
</table>
<form action="send.jsp" name="mail" id="mail">
<table width="80%" cellpadding="1" cellspacing="5" align="center" >

</tr>

</tr>
<tr><td>收件人：</td><td><input name="receive" id="receive" type="text" size="10" readonly="readonly"/>  <input type="button" name="selectcaizhi" value="收件人列表" onClick="g_OpenWindow('list.jsp','680','400')" class="submit"></td>
</tr>
<tr><td>主题：</td><td><input name="title" type="text" size="10"/></td>
</tr>
<tr><td>内容：</td><td><textarea cols="61" rows="10"></textarea></td>

<tr align="center"><td colspan="2"><br /><input type=reset align="middle" value=" 重设 " class="submit" size="10">    
<input type=submit value=" 发送 " size="10" align="middle" name="" class="submit"></td>

</form>
</body>

子页：list.jsp

如果返回checkbox的值为单一值则直接赋给父表单，如果为多值则以“，”间隔联结成为字符串赋值！

<script language=javascript type="">
function Select(){
var addstr = "";
var chb = document.getElementsByName("receiver");
for(i=0;i<chb.length;i++)
{
if(chb[i].checked)
{
if(i==0)
{
addstr = chb[i].value;
}
else
{
addstr += "," + chb[i].value
}
}
}
window.opener.document.getElementById("receive").value =addstr;
self.close();
}
</script>

<body>
<form action="#" method="POST" name="s_form" id="s_form" onsubmit="return Select();">
<table align="center">
<tr><td colspan="5"><font color="blue"><b>NCSB系统用户列表</b></font></td>
</tr>
<%
Connection con=null;
try{
con=DBConnection.getConnection();
PreparedStatement pStmt=con.prepareStatement("select * from users order by department");
ResultSet rs=pStmt.executeQuery();
int a=0;
while(rs.next()){//每5条记录为一行显示
if(a==0){%><tr><td><input type="checkbox" id="receiver" value="<%=rs.getString("username").trim()%>" name="receiver"/><%=rs.getString("realname")%>(<%=rs.getString("department")%>)</td>
<%a++;}else if(a>0&&a<4){%><td><input type="checkbox" id="receiver" value="<%=rs.getString("username").trim()%>" name="receiver"/><%=rs.getString("realname")%>(<%=rs.getString("department")%>)</td>
<%a++;}else{%><td><input type="checkbox" id="receiver" value="<%=rs.getString("username").trim()%>" name="receiver"/><%=rs.getString("realname")%>(<%=rs.getString("department")%>)</td></tr>
<%a=0;}%>
<%}
con.close();
rs.close();
}catch(Exception e){
e.printStackTrace();
}
%>
<tr align="right"><td colspan="5">
<input type=reset align="middle" value="重设" class="submit" size="10">  
<input type=submit value="确定" size="10" align="middle" name="" class="submit""></td>
</tr>
</table>
</form>
</body>
