以下都是干货,没有别的费话,相信搞过前端的都懂得一些,这里只是记录了一遍,以便在忘时查阅,十分有用,希望对你有所帮助,代码如下:

 

一、根据浏览器判断URL跳转

 

var browserOfMobile = {
wapUrl: 'http://m.baidu.com',
versions:function(){
var u = navigator.userAgent;
return {
//mobile: !!u.match(/AppleWebKit.*Mobile.*/)||!!u.match(/AppleWebKit/), //是否为移动终端
mobile: u.match(/(iPhone|iPod|Android|ios|iPad)/i),
};
}()
}
if (browserOfMobile.versions.mobile && browserOfMobile.wapUrl != '') {
location.href = browserOfMobile.wapUrl;
}

 

 

二、低版本IE判断

 

(function() {
if(navigator.userAgent.indexOf('MSIE') != -1) {
var ieBrowser = navigator.userAgent.split(';')[1];
if(ieBrowser.indexOf('MSIE') != -1 && parseInt(($.trim(ieBrowser)).substr(5)) < 9.0) {
window.location.href = 'browser_download.html';
}
}
}());

三、判断横屏还是竖屏

 

function orient() {
if (window.orientation == 0 || window.orientation == 180) {
$("body").attr("class", "portrait");
orientation = 'portrait';
return false;
}
else if (window.orientation == 90 || window.orientation == -90) {
$("body").attr("class", "landscape");
orientation = 'landscape';

return false;
}
}

四、监测浏览器是android的还是ios的

 

var browser = {
versions: function() {
var u = navigator.userAgent;
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.*/) || !!u.match(/AppleWebKit/), //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 || u.indexOf('Mac') > -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.ios || browser.versions.iPhone || browser.versions.iPad) {
window.location="https://itunes.apple.com/xxx";
}
else if (browser.versions.android) {
window.location="http://xxx/xxx.apk";
}

// document.writeln("语言版本: " + browser.language);
// document.writeln(" 是否为移动终端: " + browser.versions.mobile);
// document.writeln(" ios终端: " + browser.versions.ios);
// document.writeln(" android终端: " + browser.versions.android);
// document.writeln(" 是否为iPhone: " + browser.versions.iPhone);
// document.writeln(" 是否iPad: " + browser.versions.iPad);
// document.writeln(navigator.userAgent);

五、判断手机类型

 

window.onload = function () {
var u = navigator.userAgent;
if (u.indexOf('Android') > -1 || u.indexOf('Linux') > -1) { //安卓手机
alert("安卓手机");
} else if (u.indexOf('iPhone') > -1) { //苹果手机
alert("苹果手机");
} else if (u.indexOf('Windows Phone') > -1) { //winphone手机
alert("winphone手机");
}
}

六、判断操作系统

 

function detectOS() {
var sUserAgent = navigator.userAgent;
var isWin = (navigator.platform == "Win32") || (navigator.platform == "Windows");
var isMac = (navigator.platform == "Mac68K") || (navigator.platform == "MacPPC") || (navigator.platform == "Macintosh") || (navigator.platform == "MacIntel");
if (isMac) return "Mac";
var isUnix = (navigator.platform == "X11") && !isWin && !isMac;
if (isUnix) return "Unix";
var isLinux = (String(navigator.platform).indexOf("Linux") > -1);
if (isLinux) return "Linux";
if (isWin) {
var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1;
if (isWin2K) return "Win2000";
var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 || sUserAgent.indexOf("Windows XP") > -1;
if (isWinXP) return "WinXP";
var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1;
if (isWin2003) return "Win2003";
var isWinVista= sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;
if (isWinVista) return "WinVista";
var isWin7 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;
if (isWin7) return "Win7";
}
return "other";
}
document.writeln("您的操作系统是:" + detectOS());

七、判断APP浏览器(微信、微博、QQ、android、ios)

 

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
}
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
}
