移动Safari浏览器页面卸载深层链接/隐藏/模糊(Mobile Safari Page unloa

我期待在移动Safari浏览器的事件时，页面已经被隐藏由于重定向，将检测。我想直接打开我的应用程序，如果用户已经安装它，然后尝试的Facebook如果已安装，如果没有的话去网页该ID。

如果安装了“MYAPP”，然后MYAPP被打开。但Safari的标签仍然被重定向到facebook.com
如果未安装“的myapp”，但Facebook是，那么Facebook iOS应用被打开。但Safari的标签仍然被重定向到facebook.com

我创建了一个测试环节与下面的HTML / JS：

    <!DOCTYPE html>
    <html>
    <head>
            <title>Redirect Test</title>
            <script type='text/javascript' src='//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js'></script>
            <meta name='viewport' content='initial-scale = 1.0,maximum-scale = 1.0' />
    </head>
    <body>
    <button>Open Oreo</button>
    <script type='text/javascript'>
    jQuery(function(){
            jQuery( 'button' ).on( 'click', function(){
                    var myid = null, fbid = null;

                    // Watch for page leave to kill timers
                    jQuery( window ).on( 'pagehide pageshow blur unload', function(){
                            if ( myid ) {
                                    clearTimeout( myid );
                            }
                            if ( fbid ) {
                                    clearTimeout( fbid );
                            }
                    });

                    window.location = "myapp://fbprofile/oreo";
                    var myid = setTimeout(function(){

                            // My app doesn't exist on device, open facebook
                            window.location = "fb://profile/oreo";
                            fbid = setTimeout(function(){

                                    // Facebook doesn't exist on device, open facebook mobile
                                    window.location = "https://www.facebook.com/oreo";
                            }, 100);
                    }, 100);
            });
    });
    </script>
    </body>
    </html>

漂亮的代码。
编辑：（有关添加删除建议return false;

尝试设置你的内单向setTimeout在短短清除超时代替功能。（我发现，结算是间隔更有效的简单的1次的setTimeout调用代替）。另外，我想检查本机应用程序协议就像我之前，为了确保用户不会在桌面浏览器app://或fb://为这些浏览器将尝试跟随该位置，并最终显示错误。

尝试：

<!DOCTYPE html>

    <title>Redirect Test</title>

jQuery(function(){
    jQuery( 'button' ).on( 'click', function(){

        // Don't give desktop browsers a chance to fail on a nativeapp:// protocol
        if(!mobileExp.test(navigator.userAgent)) {
            window.location = "https://www.facebook.com/oreo";
            return;
        }

        var clicked = +new Date, timeout = 100;

        window.location = "myapp://fbprofile/oreo";

        setTimeout(function(){
            // If we're still here after a (timeout), try native facebook app
            if (+new Date - clicked < timeout*2){
                console.log('clicked '+ (+new Date - clicked) +' ago- go to FB');
                window.location = "fb://profile/oreo";
            } else {
                console.log('too late for facebook');
            }
            setTimeout(function(){
                // If we're still here after another (timeout), try facebook web app
                if (+new Date - clicked < timeout*2){
                    console.log('clicked '+ (+new Date - clicked) +' ago- go to browser');
                    window.location = "https://www.facebook.com/oreo";
                } else {
                    console.log('too late for browser');
                }
            }, timeout);
        }, timeout);
    });
});
</script>
</body>
</html>

当然，取消注释控制台日志，做一些与价值实验timeout 。在IOS 6.1 Safari浏览器和Safari 6.0.2的Mac测试成功这个确切的代码。希望能帮助到你！
