Navigator对象：
navigator对象包含有关浏览器的所有信息，且支持所有浏览器。
navigator对象有一个属性为userAgent，这是一个只读的字符串，声明了浏览器用于HTTP请求的用户代理头的值。所以我们可以通过判断navigator.userAgent里面是否包含某些值来判断。
推荐
const detectDeviceType = () =>
/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)
? 'Mobile'
: 'Desktop';
// 事例
detectDeviceType(); // "Mobile" or "Desktop"
方法一：
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";
};
方法二：
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.abc.com";
}
方法三：
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
};
}();
if(os.isAndroid || os.isPhone){
alert("-----");
}
方法四：
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：
<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abc.com页面
if(system.win||system.mac||system.xll){
}else{
window.location.href="http://abc.com";
}
</script>
方法六：
<script language="javascript">
function is_mobile() {
var regex_match = /(nokia|iphone|android|motorola|^mot-|softbank|foma|docomo|kddi|up.browser|up.link|htc|dopod|blazer|netfront|helio|hosin|huawei|novarra|CoolPad|webos|techfaith|palmsource|blackberry|alcatel|amoi|ktouch|nexian|samsung|^sam-|s[cg]h|^lge|ericsson|philips|sagem|wellcom|bunjalloo|maui|symbian|smartphone|midp|wap|phone|windows ce|iemobile|^spice|^bird|^zte-|longcos|pantech|gionee|^sie-|portalmmm|jigs browser|hiptop|^benq|haier|^lct|operas*mobi|opera*mini|320x320|240x320|176x220)/i;
var u = navigator.userAgent;
if (null == u) {
return true;
}
var result = regex_match.exec(u);
if (null == result) {
return false
} else {
return true
}
}
if (is_mobile()) {
document.location.href= 'http://domain.com'; //修改http://domain.com为你所需跳转目标页地址
}
