Javascript - Fullscreen mode on Chrome, Firefox

To enable fullscreen mode in modern browsers like Chrome and Firefox, you can use the Fullscreen API. Here's a basic example of how to toggle fullscreen mode for an element:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Fullscreen Mode</title> <style> #fullscreen-element { width: 100vw; height: 100vh; background-color: lightgray; } </style> </head> <body> <div id="fullscreen-element"> <button id="toggle-fullscreen">Toggle Fullscreen</button> </div> <script> document.getElementById('toggle-fullscreen').addEventListener('click', toggleFullscreen); function toggleFullscreen() { const element = document.getElementById('fullscreen-element'); if (!document.fullscreenElement && !document.webkitFullscreenElement && !document.mozFullScreenElement) { if (element.requestFullscreen) { element.requestFullscreen(); } else if (element.webkitRequestFullscreen) { element.webkitRequestFullscreen(); } else if (element.mozRequestFullScreen) { element.mozRequestFullScreen(); } } else { if (document.exitFullscreen) { document.exitFullscreen(); } else if (document.webkitExitFullscreen) { document.webkitExitFullscreen(); } else if (document.mozCancelFullScreen) { document.mozCancelFullScreen(); } } } </script> </body> </html>

In this example:

  • We have an element (#fullscreen-element) that we want to toggle into fullscreen mode.
  • When the button (#toggle-fullscreen) is clicked, the toggleFullscreen function is called.
  • Inside the toggleFullscreen function, we check if the document is currently in fullscreen mode using various vendor-specific properties (document.fullscreenElement, document.webkitFullscreenElement, document.mozFullScreenElement).
  • If the document is not in fullscreen mode, we request fullscreen mode for the #fullscreen-element using the appropriate vendor-specific method (requestFullscreen, webkitRequestFullscreen, mozRequestFullScreen).
  • If the document is already in fullscreen mode, we exit fullscreen mode using the appropriate method (exitFullscreen, webkitExitFullscreen, mozCancelFullScreen).
