1、用户界面：
<script language="JavaScript">
function CheckAll(form)
{for (var i=0;i<form.elements.length;i++)
{var e = form.elements[i];
if (e.name != 'chkall')
e.checked = form.chkall.checked;
}
}
</script>

</head>

<body>
<form method="post" action="del.asp" name="form1">
<table>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件1</td>
</tr>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件2</td>
</tr>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件3</td>
</tr>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件4</td>
</tr>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件5</td>
</tr>
<tr>
       <td ><input type="checkbox" value="111" name="TradeName">电子邮件6</td>
</tr>

<tr>
       <td bgcolor="#F1FBFC" height="25" colspan="2">
           <p align="left"><input type="checkbox" name="chkall" value="on" onclick="CheckAll(this.form)"><font color="#FF9900">选中所有显示的消息</font></p>
       </td>
<center>


   </tr>
</table>
</form>
2、删除文件del.asp
<%
     '这行写连接数据库的代码
     dim ID,strID
     strID=""
     For Each    strID In Request.Form("TradeName")
             ID=Cint(strID)
           if strID<>"" then
                   DelRs = Server.CreateObject("ADODB.Recordset")
                 Conn.Execute "Delete From Tbname where ID="&Cstr(ID)
               strID=""
       end if
Next

   Conn.Close
   Set Conn = Nothing
   Response.Redirect "成功删除！"
%>
