Tips for exiting a web app that is taking up your entire screen

We're currently working on making our web app run in full screen mode. We were able to achieve this by implementing these meta tags:

    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="default">
    <meta name="apple-mobile-web-app-title" content="Full Screen">

Now, whenever the web app is launched from the home screen of an iPhone or Android device, it will open in full screen mode without any browser controls.

Our next step is to provide users with a way to exit the app. I was considering creating a menu with a quit button, but using window.close() resulted in an error message in Chrome:

Scripts may close only the windows that were opened by it.

What would be the proper approach to address this issue?

If you want to exit full screen mode, you can do so by using the following script:

 function closeFullScreenMode(element) { 
        var requestMethod = element.exitFullscreen ||
                                                  element.mozCancelFullScreen || 
                                                  element.webkitExitFullscreen || 
                                                  element.msExitFullscreen; 
         if (requestMethod) { 
               requestMethod.call(element); 
         } else { 
               console.log("Error: Request method not found."); 
          } 
     }

To use this script, simply call it like this:

       var $exitButton = $("#exit-button"); 
       $exitButton.on("click", function() { 
                    var elem = document;
                    closeFullScreenMode(elem); 
        });

An issue that may arise with using window.close() is that you need to open the window first using window.open(). This allows JavaScript to then correctly close the window.

For example:

 var newWindow = window.open();
 newWindow.close(); // this will work.

Check out this helpful guide to learn about using the HTML5 fullscreen api

To exit full screen mode, you can use the following code:

if (document.exitFullscreen) {
    document.exitFullscreen();
} else if (document.webkitExitFullscreen) {
    document.webkitExitFullscreen();
} else if (document.mozCancelFullScreen) {
    document.mozCancelFullScreen();
} else if (document.msExitFullscreen) {
    document.msExitFullscreen();
}

You can implement the above code in a click method of any DOM element, for example using jQuery:

$("#exitFullScreen").click(function(){
    // implementation of the exit fullscreen code
        if (document.exitFullscreen) {
        document.exitFullscreen();
    } else if (document.webkitExitFullscreen) {
        document.webkitExitFullscreen();
    } else if (document.mozCancelFullScreen) {
        document.mozCancelFullScreen();
    } else if (document.msExitFullscreen) {
        document.msExitFullscreen();
    }
});
