IE下如何全屏？

Question

        if (this.screen) {
          var docElm = document.documentElement;
          //W3C  
          if (docElm.requestFullscreen) {
            docElm.requestFullscreen();
          }
          //FireFox  
          else if (docElm.mozRequestFullScreen) {
            docElm.mozRequestFullScreen();
          }
          //Chrome等  
          else if (docElm.webkitRequestFullScreen) {
            docElm.webkitRequestFullScreen();
          }
          //IE11
          else if (docElm.msRequestFullscreen) {
            docElm.msRequestFullscreen();
          }
        } else {
          if (document.exitFullscreen) {
            document.exitFullscreen();
          }
          else if (document.mozCancelFullScreen) {
            document.mozCancelFullScreen();
          }
          else if (document.webkitCancelFullScreen) {
            document.webkitCancelFullScreen();
          }
          else if (document.msExitFullscreen) {
            document.msExitFullscreen();
          }
        }

chrome没有没问题
但是IE的布局会错位
用的ElementUI
