今天在做一个项目，客户想要玩家电脑端登陆时候跳转到app下载页面，而手机端跳转到注册页面。如下代码可以实现：
<head>
<meta charset="UTF-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no" />
<script type="text/javascript">
function browserRedirect() {
var sUserAgent = navigator.userAgent.toLowerCase();
var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
var bIsMidp = sUserAgent.match(/midp/i) == "midp";
var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
var bIsAndroid = sUserAgent.match(/android/i) == "android";
var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
//跳转移动端页面,跳转到新浪首页
window.location.href="http://www.sina.com.cn";
} else {
//跳转pc端页面，跳转到百度首页
window.location.href="http://www.baidu.com";
}
}
browserRedirect();
</script>
</head>
===========================
上面红色部分放到登录页面头部即可。
