我正在移动safari上寻找一个事件,该事件将检测页面何时因重定向而隐藏。如果用户安装了我的应用程序,我想直接打开它,如果安装了,则尝试使用facebook,如果没有,则转到该id的网页。
- 如果安装了"myapp",则myapp将打开。但狩猎标签仍然被重定向到facebook.com
- 如果没有安装myapp,但安装了facebook,则会打开facebook ios应用程序。但狩猎标签仍然被重定向到facebook.com
我用以下HTML/JS:创建了一个测试链接
<!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:(删除了关于添加return false;
的建议)
尝试在setTimeout
函数中设置一个检查,而不是仅清除超时。(我发现清除间隔比简单的1次setTimeout调用更有效)。此外,在尝试像我的app://
或fb://
这样的本机应用程序协议之前,我会检查以确保用户不在桌面浏览器上,因为这些浏览器会试图遵循该位置,最终显示错误。
尝试:

setTimeout(function(){

window.location = "fb://profile/oreo";

console.log('too late for facebook');

setTimeout(function(){

当然,取消对控制台日志的注释,并对timeout
的值进行一些实验。这个确切的代码在IOS 6.1 Safari和Safari 6.0.2 Mac中测试成功。希望它能有所帮助!
