[解决办法]
<script language= "text/javascript ">
function delPer()
{
document.form1.action= "doMail.jsp?tag=delPer ";
document.form1.submit();
}
</script>
完你的文档中没有 form1 这个 FORM 呀！
[解决办法]
早上看到过这个问题了，解决是input的name不要和js的函数名一行，你改了一个，但是还少改了一个，下面还有个 <input name= "delPer " type= "button " id= "delforever " value= "彻底删除 " onClick= "delPer() "> ，去掉这里的name就正常了
