最近制作了一个二维码，在android平台会进去android下载渠道，如果是ios系统，则进去appStore下载，代码如下

<! DOCTYPE html>
<meta charset= "UTF-8" >
<title>Title</title>
<body style= "font-size:40px;" >
<div id= "Tips" style= "padding:50px 0;width:100%;margin:0 auto;display:none;" >

</div>

</body>
<script type= "Text/javascript" >

var u = navigator.useragent, app = Navigator.appversion;
return {

};
}(),

};

if (!browser.versions.mobile) {

If not mobile scan QR code
Alert ("Please scan the QR code with your phone");
}else if (browser.versions.android) {

If Android, go directly to the download link
location.href= ' http://url.cn/42G7PNz ';
}
else if (browser.versions.weixin && (Browser.versions.ios | | browser.versions.iPad)) {

If it is an iOS system and is turned on, a reminder is displayed (direct jump AppStore not supported)
document.getElementById ("Tips"). Style.display = "block";
}else if (Browser.versions.ios | | browser.versions.iPad) {

If it is an iOS system and is not open in, jump directly to AppStore
location.href= ' https://itunes.apple.com/cn/app/sui-shi-bao/id1097442883?mt=8 ';
