判断设备访问类型是PC端还是WAP端

在开发项目中，可能经常会用到。判断用户访问的是PC还是手持设备，如果是手持设备自动访问wap地址。

方法一：

JavaScript

var browser={
versions:function(){
var u = navigator.userAgent, app = navigator.appVersion;
return {//移动终端浏览器版本信息
trident: u.indexOf('Trident') > -1, //IE内核
presto: u.indexOf('Presto') > -1, //opera内核
webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器
iPhone: u.indexOf('iPhone') > -1 , //是否为iPhone或者QQHD浏览器
iPad: u.indexOf('iPad') > -1, //是否iPad
webApp: u.indexOf('Safari') == -1, //是否web应该程序，没有头部与底部
weixin: u.indexOf('MicroMessenger') > -1, //是否微信
qq: u.match(/\sQQ/i) == " qq" //是否QQ
};
}(),
language:(navigator.browserLanguage || navigator.language).toLowerCase()
}

if(browser.versions.mobile || browser.versions.ios || browser.versions.android ||
browser.versions.iPhone || browser.versions.iPad){
window.location = "http://m.zhaizhainv.com";
}

方法二：

JavaScript

function IsPC(){
var userAgentInfo = navigator.userAgent;
var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");
var flag = true;
for (var v = 0; v < Agents.length; v++) {
if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }
}
return flag;
}

if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) {
//alert(navigator.userAgent);
window.location.href ="iPhone.html";
} else if (/(Android)/i.test(navigator.userAgent)) {
//alert(navigator.userAgent);
window.location.href ="Android.html";
} else {
window.location.href ="pc.html";
};

方法三：

来自IM-QQ

JavaScript

var os = function() {
var ua = navigator.userAgent,
isWindowsPhone = /(?:Windows Phone)/.test(ua),
isSymbian = /(?:SymbianOS)/.test(ua) || isWindowsPhone,
isAndroid = /(?:Android)/.test(ua),
isFireFox = /(?:Firefox)/.test(ua),
isChrome = /(?:Chrome|CriOS)/.test(ua),
isTablet = /(?:iPad|PlayBook)/.test(ua) || (isAndroid && !/(?:Mobile)/.test(ua)) || (isFireFox && /(?:Tablet)/.test(ua)),
isPhone = /(?:iPhone)/.test(ua) && !isTablet,
isPc = !isPhone && !isAndroid && !isSymbian;
return {
isTablet: isTablet,
isPhone: isPhone,
isAndroid : isAndroid,
isPc : isPc
};
}();

使用方法：

if(os.isAndroid || os.isPhone){

alert("wap");

}

方法四：

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)){
window.location.href="手机页面";
}else if(/iPad/i.test(navigator.userAgent)){
window.location.href="平板页面";
}else{
window.location.href="其他移动端页面"
}
}catch(e){}
}
}

方法五：

JavaScript

<script language="javascript">
//平台、设备和操作系统
var system ={
win : false,
mac : false,
xll : false
};
//检测平台
var p = navigator.platform;
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
//跳转语句，如果是手机访问就自动跳转到wap页面
if(system.win||system.mac||system.xll){
}else{
window.location.href="手机页面地址";
}
</script>
