方法一：
var isPC = function () { var userAgentInfo = navigator.userAgent.toLowerCase(); 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; }
前端调用 不需要jq
<script src="../../js/isPc.js"></script> <script> var isPC = isPC(); if(!isPC){ //window.location.href = 'm/index.html';
//执行移动端要执行的代码
console.log("移动端"); } </script>
方法二：
js判断用户的浏览设备是移动设备还是PC
<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";
document.writeln("您的浏览设备为：");
if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
document.writeln("phone");
} else {
document.writeln("pc");
}
}
browserRedirect();
</script>
判断详细浏览器设备信息：
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 }; }(), language: (navigator.browserLanguage || navigator.language).toLowerCase() } if (browser.versions.mobile) {//判断是否是移动设备打开。browser代码在下面 var ua = navigator.userAgent.toLowerCase();//获取判断用的对象 if (ua.match(/MicroMessenger/i) == "micromessenger") { //在微信中打开 setInterval(WeixinJSBridge.call('closeWindow'),2000); } if (ua.match(/WeiBo/i) == "weibo") { //在新浪微博客户端打开 } if (ua.match(/QQ/i) == "qq") { //在QQ空间打开 } if (browser.versions.ios) { //是否在IOS浏览器打开 } if(browser.versions.android){ //是否在安卓浏览器打开 } } else { //否则就是PC浏览器打开 window.close(); }
