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 = 0v
if(userAgentInfo.indexOf(Agents[v]) >0) { flag = falsebreak}
}
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

}
}(),
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"
}
方法三： 摘自im- qq
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("-----")
}
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"
}elseif(/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
//平台、设备和操作系统
varsystem ={
win:false,
mac:false,
xll:false
}
//检测平台
varp = 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caibaojian.com页面
if(system.win||system.mac||system.xll){
}else{
window.location.href="http://caibaojian.com"
}
方法六
functionis_mobile(){
varregex_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
varu = navigator.userAgent
if(null== u) {
returntrue
}
varresult = regex_match.exec(u)
if(null== result) {
returnfalse
}else{
returntrue
}
}
if(is_mobile()) {
document.location.href='http://caibaojian.com'//修改http://caibaojian.com为你所需跳转目标页地址
}
方法7 百度webapp版
<!---识别手机或电脑的js开始--->
(function(){
varres = GetRequest()
varpar = res['index']
if(par!='gfan'){
varua=navigator.userAgent.toLowerCase()
varcontains=function(a, b){
if(a.indexOf(b)!=-1){returntrue}
}
//将下面的http://caibaojian.com改成你的wap手机版页面地址 如我的 http://caibaojian.com
vartoMobileVertion =function(){
window.location.href ='http://caibaojian.com/'
}
if(contains(ua,"ipad")||(contains(ua,"rv:1.2.3.4"))||(contains(ua,"0.0.0.0"))||(contains(ua,"8.0.552.237"))){returnfalse}
if((contains(ua,"android") &&contains(ua,"mobile"))||(contains(ua,"android") &&contains(ua,"mozilla")) ||(contains(ua,"android") &&contains(ua,"opera"))
||contains(ua,"ucweb7")||contains(ua,"iphone")){toMobileVertion()}
}
})()
functionGetRequest(){
varurl = location.search//获取url中"?"符后的字串
vartheRequest =newObject()
if(url.indexOf("?") !=-1) {
varstr = url.substr(1)
strs = str.split("&")
for(vari =0i <strs.lengthi ++) {
theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1])
}
}
returntheRequest
}
应该把JS 放在页面首页加载 就行function IsPC() {
var userAgentInfo = navigator.userAgent
var Agents = ["Android", "iPhone",
"SymbianOS", "Windows Phone",
"iPad", "iPod"]
var flag = true
for (var v = 0v <Agents.lengthv++) {
if (userAgentInfo.indexOf(Agents[v]) >0) {
flag = false
break
}
}
return flag
}
var flag = IsPC()//true为PC端，false为手机端
alert(flag)
思路：根据请求来进行判断用户的客户端，从而进行选择访问方法。
代码及注释如下：
<script type="text/javascript"><!--
//平台、设备和操作系统
var system = {
win: false,
mac: false,
xll: false,
ipad: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)
system.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false
//跳转语句，如果是PC访问就自动跳转到所要访问的页面
if (system.win || system.mac || system.xll||system.ipad) {
//默认访问电脑端浏览
} else {
window.location.href = "手机端浏览的地址"
}
-->
</script>
