用于deeplink的js方法(判断手机是否安装app)

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

 

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;
}
})();
