判断是手机端还是PC短访问

第一种：判断是手机访问还是PC访问

<script>
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) ){

//跳转到PC端地址
window.location.href='http://www.jd.com';
}else{
//跳转到移动端地址
window.location.href='http://m.jd.com';
}
}

browserRedirect();
</script>

第二种：判断是手机访问还是PC访问

var system ={};
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){//如果是电脑跳转到百度
window.location.href="http://www.baidu.com/";
}else{ //如果是手机,跳转到谷歌
window.location.href="http://www.google.cn/";
}

第三种：判断是手机访问还是PC访问

<script>

if(navigator.platform.indexOf('Win32')!=-1){
//pc
//window.location.href="电脑网址";
}else{
//手机
window.location.href="手机网址";
}
</script>

第四种：百度判断是手机还是PC访 问

<script src="http://siteapp.baidu.com/static/webappservice/uaredirect.js"type="text/javascript"></script>
<script type="text/javascript">uaredirect("http://m.XXX.com")//手机网址;</script>

将代码网址部分改成你网站的手机网址就Ok,当然可以是任意网址！

第五种：判断是手机还是PC跳转到指定的地址*

下面这段代码是判断浏览器是手机浏览器，然后自动跳转到mobile.com，怎么修改，才能

把不是用手机浏览器的人，在上mobile.com的时候，自动跳转到PC.COM

<script type="text/javascript">

if(/AppleWebKit.*Mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|
SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia| SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){
if(window.location.href.indexOf("?mobile")<0){
try{
if(/Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){
//手机
window.location.href="http://www.mobile.com";
}else if(/iPad/i.test(navigator.userAgent)){
//ipad
window.location.href="http://ipad.com"
}else{
//电脑
window.location.href="http://pc.com"
}
}catch(e){}
}
}
</script>
