<img id="image" src="path/to/image.postfix" alt="img" />

// 退出全屏
ngAfterViewInit() {
  const image = document.getElementById('image');
  image.addEventListener('click', (event: any) => {
    if(document.fullscreenElement === image) {
      document.exitFullscreen();
    }
    event.preventDefault();
  })
}
// 全屏查看
public fullscreenView(): void {
  const image = document.getElementById('image');
  image.requestFullscreen()
} 

export class Utils {
  public static GotoFullscreen(dom: any): void {
    if (dom.requestFullscreen) {
      dom.requestFullscreen()
    } else if (dom.mozRequestFullScreen) {
      dom.mozRequestFullScreen()
    } else if (dom.WEBkitRequestFullscreen) {
      dom.webkitRequestFullscreen()
    } else if (dom.msRequestFullscreen) {
      dom.msRequestFullscreen()
    } else {
      console.error('当前浏览器不支持部分全屏！')
    }
  }
  public static exitFullscreen(dom: any): void {
    if (dom.exitFullscreen) {
      dom.exitFullscreen()
    } else if (dom.webkitExitFullscreen) {
      dom.webkitExitFullscreen()
    } else if (dom.msExitFullscreen) {
      dom.msExitFullscreen()
