I saw that the popup always needs some delay if not open directly with the link ... see this working example
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html> <head> <title>popup</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" /> <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script> <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script> <meta http-equiv="Content-Type" content="text/html; charset= ISO-8859-5"> </head> <body> <div data-role="page" id="myPage"> <div data-role="content"> <h1>Popup</h1> <div data-role="popup" id="popupBasic"> <p>This is a completely basic popup, no options set.</p> </div> <div data-role="popup" id="popupMatricula"> <p>This is the Matricula popup.</p> </div> </div> <script> $(document).bind('pageinit', function() { setTimeout(function(){ $("#popupBasic").popup(); $("#popupBasic").popup("open"); }, 100); setTimeout(function(){ $("#popupBasic").popup("close"); }, 3000); setTimeout(function(){ $("#popupMatricula").popup(); $("#popupMatricula").popup("open"); }, 3100); }); </script> </div> </body> </html>
EDIT : A short delay is needed for Firefox, but not for Chrome and Android browsers, as @Jasper is checked here
