<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>

<body>
    <a id="openApp">点击打开贴吧客户端</a>
    <p id="mod_pop" style="display:none;">请在其他浏览器中打开</p>

    <script type="text/javascript">
        window.onload = function () {
            function isWeixin() {
                var ua = navigator.userAgent.toLowerCase(); //获取判断用的对象
                if (ua.match(/MicroMessenger/i) == "micromessenger") {
                    return true; //微信打开
                } else {
                    return false; //不是微信打开
                }
            }

            document.getElementById('openApp').onclick = function (e) {
                if (isWeixin()) {
                    var modPop = document.getElementById('mod_pop');
                    modPop.style.display = "block";
                } else {
                    if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) { //ios判断
                        window.location.href = "com.baidu.tieba://"; //通过app打开协议来打开app
                        window.setTimeout(function () {

                        }, 20)
                    } else if (/(Android)/i.test(navigator.userAgent)) { //Android判断
                        var state = null;
                        try {
                            state = window.open("com.baidu.tieba://");
                        } catch (e) {}
                        if (state) {
                            window.close();
                        } else {
