I thought that the reason is my JS script that integrates Vimeo Player API but it ends up that even Vimeo's embed link doesn't work at all.

In IE11 and Chrome45 I can use it fine In Safari8.0.4, like in older versions of Chrome, it gives the error "unexpected use of reserved word 'let'" In Firefox the let keyword only works inside , but this script type isn't even recognized as Javascript in IE11, Chrome45, Safari8. Here's a JSFiddle that shows it in action: https://jsfiddle.net/p6cgtyg6/1/ So -- I don't mind requiring users to use modern versions of their browsers. And I don't mind excluding Safari if there honestly is no

I created a desktop application with Swing Application Framework, now how can I convert it to an applet? The main class extends SingleFrameApplication. EDITED: This is the starting class, used NetBeans GUI builder: public class PhotoApp extends SingleFrameApplication { /** * At startup create and show the main frame of the application. */ @Override protected void startup() { show(new PhotoView(this)); } /** * This method is to initialize the specified window by injecting resources. * Windows shown in our application come fully initialized from the GUI * builder, so this additional
