代碼功能:
判斷手機(jī)/平板是否安裝app
如果安裝 則調(diào)用app的scheme，傳入url當(dāng)作參數(shù)，來(lái)做后續(xù)操作
如果沒(méi)有安裝 則跳轉(zhuǎn)到app store/google play 下載app

復(fù)制代碼 代碼如下:

(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;
}
})();
