In the application I'm creating, I want the screen to be full when the user logs in (Similar to Chrome F11). Then, after logging out, it should return to its original position.
In the application I'm creating, I want the screen to be full when the user logs in (Similar to Chrome F11). Then, after logging out, it should return to its original position.
Implementing a full-screen toggle function without adding an extra library dependency can be achieved with the following code snippet:
/**
* Toggles the fullscreen mode.
*/
toggleFullscreen() {
if (document.webkitIsFullScreen) {
this._exitFullscreen();
} else {
this._activateFullscreen();
}
}
/**
* Activate Full Screen Mode.
*/
private _activateFullscreen() {
let fullscreenElement = document.documentElement;
if (fullscreenElement.requestFullscreen) {
fullscreenElement.requestFullscreen();
} else if (fullscreenElement.mozRequestFullScreen) {
/* Firefox */
fullscreenElement.mozRequestFullScreen();
} else if (fullscreenElement.webkitRequestFullscreen) {
/* Chrome, Safari and Opera */
fullscreenElement.webkitRequestFullscreen();
} else if (fullscreenElement.msRequestFullscreen) {
/* IE/Edge */
fullscreenElement.msRequestFullscreen();
}
}
/**
* Exits Full Screen Mode.
*/
private _exitFullscreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
} else if (document.mozCancelFullScreen) {
/* Firefox */
document.mozCancelFullScreen();
} else if (document.webkitExitFullscreen) {
/* Chrome, Safari and Opera */
document.webkitExitFullscreen();
} else if (document.msExitFullscreen) {
/* IE/Edge */
document.msExitFullscreen();
}
}

There's also a fantastic Angular 2 Example available:
import {Directive, HostListener} from '@angular/core';
import * as screenfull from 'screenfull';
@Directive({
selector: '[toggleFullscreen]'
})
export class ToggleFullscreenDirective {
@HostListener('click') onClick() {
if (screenfull.enabled) {
screenfull.toggle();
}
}
}
Next, in your HTML code:
<button toggleFullscreen>Toggle fullscreen<button>
You can then respond to events and manage fullscreen mode based on your specific requirements.
