JS判断电脑手机自动跳转代码

以下代码是插入到手机模板中

<script type="text/javascript">
var system = {
win: false,
mac: false,
xll: false
};
var p = navigator.platform;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
if (system.win || system.mac || system.xll) {
window.location.href = "www.51dev.com";
} else {}
</script>

以下是电脑跳转，插入到电脑模板的js文件中

var browser = {
versions: function () {
var u = navigator.userAgent, app = navigator.appVersion;
return {
trident: u.indexOf('Trident') > -1,
presto: u.indexOf('Presto') > -1,
webKit: u.indexOf('AppleWebKit') > -1,
gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1,
mobile: !!u.match(/AppleWebKit.*Mobile.*/) || !!u.match(/AppleWebKit/),
ios: !!u.match(/i[^;]+;( U;)? CPU.+Mac OS X/),
android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1,
iPhone: u.indexOf('iPhone') > -1 || (u.indexOf('Mac') > -1 && u.indexOf
('Macintosh') < 0),
iPad: u.indexOf('iPad') > -1,
webApp: u.indexOf('Safari') == -1
};} (),language: (navigator.browserLanguage || navigator.language).toLowerCase()}
if(!browser.versions.iPad){
if (browser.versions.android || browser.versions.iPhone) {
self.location = "www.51dev.com";
}}
