js判断客户端是移动端还是PC端 JavaScript

//判断客户端是移动端还是pc端
//userAgent用户代理
function IsPC() { var userAgentInfo = navigator.userAgent; var Agents = ["Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod"]; var flag = true; for (var i = 0; i < Agents.length; i++) { if (userAgentInfo.indexOf(Agents[i]) !=-1) { flag = false; break; } } return flag; }
//方法2，使用正则表达式

if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) { //alert(navigator.userAgent); ipone移动端 window.location.href ="https://www.it610.com/article/iPhone.html"; } else if (/(Android)/i.test(navigator.userAgent)) { //alert(navigator.userAgent); android移动端 window.location.href ="https://www.it610.com/article/Android.html"; } else { //PC端 window.location.href ="https://www.it610.com/article/pc.html"; };

方法3

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4

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 };
