今天突然看到一段很好的代码,分享给大家,顺便也给自己留个笔记,js判断浏览器的环境具体如下:方法一:
// 判断浏览器函数
function isMobile(){

if(window.navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i)) {

return true; // 移动端

}else{

return false; // PC端

}
}

// 判断浏览器函数
function isMobile(){

if(window.navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i)) {

return true; // 移动端

}else{

return false; // PC端

}
}
方法二:这个方法摘自:im.qq.com
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("-----");
}

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("-----");
}
判断是否为微信客户端:代码1
window.isInWeixinApp = function() {

return /MicroMessenger/.test(navigator.userAgent);

};
window.isInWeixinApp = function() {

return /MicroMessenger/.test(navigator.userAgent);

};
/**

* 判断是否是微信环境

*/

function getIsWxClient () {

var ua = navigator.userAgent.toLowerCase();

if (ua.match(/MicroMessenger/i) == "micromessenger") {

return true;

}

return false;

};
/**

* 判断是否是微信环境

*/

function getIsWxClient () {

var ua = navigator.userAgent.toLowerCase();

if (ua.match(/MicroMessenger/i) == "micromessenger") {

return true;

}

return false;

};代码2
var isWechart = function () {

var rst = true

if(window.navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i)){

var ua = navigator.userAgent.toLowerCase();

if (!(ua.match(/MicroMessenger/i) == "micromessenger")) {

rst = false;

}

}else {

rst = false;

}

return rst;
}


var isWechart = function () {

var rst = true

if(window.navigator.userAgent.match(/(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i)){

var ua = navigator.userAgent.toLowerCase();

if (!(ua.match(/MicroMessenger/i) == "micromessenger")) {

rst = false;

}

}else {

rst = false;

}

return rst;
}

判断微信浏览器是PC端还是手机端,以及手机端是微信浏览器还是非微信浏览器判断微信浏览器是PC端还是手机端,以及手机端是微信浏览器还是非微信浏览器

system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);

system.ipad = (navigator.userAgent.match(/iPad/i) != null) ? true : false;

//跳转语句,如果是手机访问就自动跳转到wap.baidu.com页面
