页面js判断浏览器类型

工作上有些页面的需求要区分pc/wap进行不同跳转；区分安卓/ios进行兼容；区分微信/qq/支付宝/第三方浏览器进行不同处理，这里做了下汇总记录，方便快速查阅。

是否是安卓/ios

是否是微信/qq/支付宝、

var ua = navigator.userAgent.toLowerCase();
if(ua.match(/MicroMessenger/i)=="micromessenger") {
    //微信环境              
} else if (ua.match(/QQ/i) == "qq") {
    //qq环境              
}else if(ua.match(/Alipay/i)=="alipay"){
     //支付宝环境    
}else{
    //第三方浏览器环境              
}

判断PC/wap端

 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) {
         //移动wap端
    } else{
        //pc端
    }
