在线急等一个提交问题
请问大虾:为什么下面代码中的隐藏表单域的value不能在脚本代码中设置?
function   forgetpass()
{
document.fm_log.bt_log.value= "forgetPassword ";
document.fm_log.action= "Log ";
document.fm_log.submit();
}

function   regist()
{
document.fm_log.bt_log.value= "regist ";
document.fm_log.action= "Log ";
document.fm_log.submit();
}
...
<form   name= "fm_log "   action= " "   method= "post ">
...
<input   type= "button "   name= "bt_log "   value= "登陆 "   onClick= "load(); ">
<input   type= "button "     value= "忘记密码 "   onClick= "forgetpass(); ">
<input   type= "button "     value= "注册 "   onClick= "regist(); ">
<input   type= "hidden "   name= "bt_log "   value= " ">


现在我想让这两个button提交到一个Servlet,通过这个隐藏表单域来区分是哪个button,可是老是不能设置成功这个bt_log的value,请问怎样才能成功设置呢?

<input type= "hidden " name= "bt_log " value= " ">

改个名字看看

你上面有个button 也叫这个名字
