这篇文章主要介绍了用于deeplink的js方法(判断手机是否安装app),需要的朋友可以参考下

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; } })();
