Mobile Safari Page unload/hide/blur for Deep Linking
Nice code.
EDIT: (removed suggestion about adding return false;)
Try setting a check within your setTimeout functions in stead of just clearing the Timeouts. (I find that clearing is much more effective for intervals in stead of simple 1-time setTimeout calls). Also, I would check to make sure the user isn't on a desktop browser before trying a native app protocol like my app:// or fb:// as those browsers will try to follow that location and end up displaying an error.
Try:
<!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'>var mobileExp = /android|avantgo|blackberry|blazer|compal|elaine|fennec|hiptop|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile|o2|opera mini|palm( os)?|plucker|pocket|pre\/|psp|smartphone|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce; (iemobile|ppc)|xiino/i;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>Of course, un-comment the console logs and do some experimenting with the value of timeout. This exact code tested successfully in IOS 6.1 Safari and Safari 6.0.2 Mac. Hope it helps!
