代码功能:

判断手机/平板是否安装app

如果安装 则调用app的scheme，传入url当作参数，来做后续操作

如果没有安装 则跳转到app store/google play 下载app

复制代码 代码如下:

(function() {

var openUrl = window.location.search;

try{

openUrl = openUrl.substring(1,openUrl.length);

}catch(e){

}

var isiOS = navigator.userAgent.match('iPad')

|| navigator.userAgent.match('iPhone')

|| navigator.userAgent.match('iPod'), isAndroid = navigator.userAgent

.match('Android'),isDesktop = !isiOS&&!isAndroid;

if (isiOS) {

setTimeout(function () { window.location = "itms-apps://itunes.apple.com/app/[name]/[id]?mt=8"; },25);

window.location = "[scheme]://[host]?url="+openUrl;

}else if(isAndroid){

window.location = "intent://[host]/"+"url="+openUrl+"#Intent;scheme=[scheme];package=[package_name];end";

}else{

window.location.href = openUrl;

}

})();
