react如何实现在网页中全屏操作？

1、utils.ts文件

var document: any = window.document;
// 展开/全屏
export function requestFullScreen(element: any) {
   
   
  var requestMethod = element.requestFullscreen || element.webkitRequestFullscreen || element.msRequestFullscreen || element.mozRequestFullScreen;
  if (requestMethod) {
   
   
    requestMethod.call(element);
  }
}
// 退出/全屏
export function exitFullScreen() {
   
   
  var exitMethod = document.exitFullscreen || document.webkitExitFullscreen || document.msExitFullscreen || document.mozCancelFullScreen;
  if
