<script type="text/javascript">
function login(){
window.self.location="login.do?command=login"
+document.getElementById("loign");
}
function addUser(){
window.self.location="loign.do?command=addUser"
+document.getElementById("loign");
}
</script>
</head>
<body>
<center><h3>用户登陆</h3><hr>
<form action=login.do id="login" method="post">
用户名：<input type="text" name="managerName" width="300"><br><br>
