我是靠谱客的博主火星上乌龟，最近开发中收集的这篇文章主要介绍javascript/jquery 简单的页面定时器自动跳转登陆界面，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

登录成功页面 success.html

// js
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>注册成功！</title>
<script type="text/javascript">
window.onload = function() {
var time = 5;
var secondEle = document.getElementById("second");
setIntervar(function() {
secondEle.innerHTML = time;
time--;
if (time == 0) {
clearIntervar(timer);
window.location.href = "login.html";// 跳转到登录页面
}
},1000);
</script>
</head>
<body>

</html>

// jquery
<!DOCTYPE html>

<script src="classes/js/jquery-2.1.0.js"></script>

<script>
$(function () {
var time = 5;
// 使用 jquery.timer插件方法
$("#second").everyTime('1s',function () {
this.innerHTML = time;
if (time == 0) {
// 三种方法
$(window).attr('location','login.html');
//$(location).attr('href','login.html');
//$(location).prop('href','login.html');
}
time--;
},6);
});
</script>

最后是 login.html 登录界面

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/WebDemo/login" method="post">
用户名：<input type="text" name="username"><br />
密码： <input type="password" name="password"><br />
<input type="submit" value="登录"><br />
</form>
</body>
</html>
