The window supports the full-screen interface by using web API. We can activate or deactivate the full-screen mode of the screen. The fullscreen API provides methods to present a specific element in a full-screen mode.
Approach:
- The onclick event will trigger the activate() method which will be for activating the full screen.
- The same will be applied for exiting from the full screen.
<button onclick="activate(document.documentElement);">
Go To Full Screen
</button>
<button onclick="deactivate();">
Leave Full Screen
</button>
Example: The following code uses the requestFullscreen() method. The same is done for exiting full screen by using exitFullscreen() method.
HTML
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content= "width=device-width, initial-scale=1.0" /> </head> <body> <h1 style="color: green">GeeksForGeeks</h1> <h2>Window fullscreen property</h2> <button onclick="activate(document.documentElement);"> Go To Full Screen </button> <button onclick="deactivate();">Leave FullScreen</button> <script> // Function for full screen activation function activate(ele) { if (ele.requestFullscreen) { ele.requestFullscreen(); } } // Function for full screen activation function deactivate() { if (document.exitFullscreen) { document.exitFullscreen(); } } </script> </body> </html> |
Output:
