How to set browser full screen using jQuery

jQuery is a popular JavaScript library that can be used to simplify web development. In this article, we will learn how to set the browser to full screen using jQuery.

In some cases, you may need to set the browser to full screen on your website or web application. This could be because you need to display your content on a larger screen, or you need to provide a better experience for your users. Whatever the reason, setting your browser to full screen is easy with jQuery.

First, we need to use jQuery to select the element that we want to set full screen. We can use the following code:

var elem = document.documentElement;

The above code selects the entire page or document as the element to be full screen. If you only want to full screen a specific element, you can use the following code:

var elem = document.getElementById("my-element");

The above code selects the element with the ID "my-element" as the element to be full screen.

Now that we have selected the element we want to go full screen, we will use the following code to achieve full screen:

if (elem.requestFullscreen) {
  elem.requestFullscreen();
} else if (elem.webkitRequestFullscreen) {
  elem.webkitRequestFullscreen();
} else if (elem.msRequestFullscreen) {
  elem.msRequestFullscreen();
}

The above code will check if the browser supports full screen and select the correct one based on the browser type method. For example, Chrome supports the webkitRequestFullscreen method.

Now that we have set the browser to full screen, we need to handle what happens when we exit full screen. We can use the following code:

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

The above code will check if the browser supports exiting full screen and select the correct method based on the browser type.

In addition to the full screen method and the exit full screen method, we can also use the following code to check whether it is currently in full screen state:

if (document.fullscreenElement || document.webkitFullscreenElement || document.msFullscreenElement) {
  // in fullscreen
} else {
  // not in fullscreen
}

The above code will check whether the browser is in full screen state and control Taichung outputs the corresponding information.

Summary:

Using jQuery you can easily achieve full-screen browser settings. We can achieve this by selecting elements, setting full screen and exiting full screen. In addition to this, we can also use code to check whether it is currently in full screen state. In actual applications, choosing different methods and techniques according to needs can better achieve full-screen browser settings.
