h5分享页面打开APP

判断是安卓还是ios

var u = navigator.userAgent;
var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android终端
var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
if(isiOS){
document.getElementById('download-app').value = 'http://baidu.com';
}else{
document.getElementById('download-app').value = 'http://jd.com/8JZ5OO';
}

页面代码

<a id="call-app" href="javascript:;" style="display: inline-block;float: right;">
<input id="download-app" type="hidden" name="storeurl" value="http://jd.com/8JZ5OO">
<div class="intoR">
<span>立即进入</span>
</div>
</a>

已下载打开APP 未下载跳转到input的value也就是下载页面

scheme_IOS和scheme_Adr这两个参数是app端给的呼起app url。

var ua = navigator.userAgent.toLowerCase();
var t;
var config = {
/*scheme:必须*/
scheme_IOS: 'lbbox1214151904://com.lababox',
scheme_Adr: 'schemedemo://aa.com/test/scheme?name=google&page=1',
download_url: document.getElementById('download-app').value,
timeout: 600
};
function openclient() {
var startTime = Date.now();
var ifr = document.createElement('iframe');
ifr.src = ua.indexOf('os') > 0 ? config.scheme_IOS : config.scheme_Adr;
ifr.style.display = 'none';
document.body.appendChild(ifr);
var t = setTimeout(function() {
var endTime = Date.now();
if (!startTime || endTime - startTime < config.timeout + 200) {
window.location = config.download_url;
} else {
}
}, config.timeout);
window.onblur = function() {
clearTimeout(t);
}
}
window.addEventListener("DOMContentLoaded", function(){
document.getElementById("call-app").addEventListener('click',
openclient, false);
}, false);
