1. 登录页 验证用户身份，登录成功之后等待一定秒数，跳转到操作页面
<html>
<head>
<title>Login.html</title>
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
<script type="text/javascript">
function checkuser() {
if($(‘uname‘ == "lala") && $(‘pwd‘) == "123") {
return true;
}else {
return false;
}
}
function $(id) {
return document.getElementById(id).value;
}
</script>
</head>
<body>
<form action="ok.html">
u:<input type="text" id="uname"/><br>
p:<input type="password" id="pwd"/><br>
<input type="submit" value="登录" onclick="return checkuser()"/>
</form>
</body>
</html>
2. 登录成功页面中，等待5秒
<html>
<head>
<title>ok.html</title>
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!--<link rel="stylesheet" type="text/css" href="./styles.css">-->
<script type="text/javascript">
function tiao() {
clearInterval(mytime);
window.open("manage.html","_self");
}
setTimeout("tiao()",5000);
function changeSec() {
//得到myspan值
$(‘myspan‘).innerText=$(‘myspan‘).innerText-1;
}
function $(id) {
return document.getElementById(id);
}
var mytime = setInterval("changeSec()",1000);
</script>
</head>
<body>
登录成功，<span id="myspan">5</span>秒后自动跳转到管理页面
</body>
</html>
3. 写一个manage.html 即可
