如下图所示,在手机浏览器中访问京东的手机版网站(m.jd.com),顶部会有一个广告图,点击这个广告图,如果手机上已经安装了京东App,则直接打开,如果没有安装,则开始下载。
1.为Android应用的启动Activity设置一个Schema,如下:
- <
- data android:host="splash" android:scheme="cundong"/>
2.用户点击浏览器中的链接时,在动态创建一个不可见的iframe,并且让这个iframe去加载步骤1中的Schema,如下:
- var ifr = document.createElement(‘iframe‘);
- ifr.src = "cundong://splash"
3,如果在指定的时间内没有跳转成功,则当前页跳转到apk的下载地址(或下载页),如下:
- window.location = download_url;
- <!doctype html>
- <html>
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
- <meta name="apple-mobile-web-app-capable" content="yes">
- <meta name="apple-mobile-web-app-status-bar-style" content="black" />
- <title>
- this‘s a demo
- </title>
- <meta id="viewport" name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,minimal-ui">

- <body>
- <div>
- <a id="J-call-app" href="javascript:;" class="label">

- </a>
- <input id="J-download-app" type="hidden" name="storeurl" value="http://m.chanyouji.cn/apk/chanyouji-2.2.0.apk">
- </div>
- <script>
- (function() {
- var ua = navigator.userAgent.toLowerCase();
- var t;
- var config = {
- /*scheme:必须*/
- scheme_IOS: ‘cundong: //‘,
- scheme_Adr: ‘cundong: //splash‘,
- download_url: document.getElementById(‘J - 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("J-call-app").addEventListener(‘click‘, openclient, false);
- },
- false);
- })()
