javascript - dom元素全屏展示

业务场景：将 html 界面上的一个 dom 元素全屏展示

使用方式

参数传入 dom 对象即可，注意不是 jQuery 对象，Vue 下兼容

/**
 * 面板全屏展示
 */
fullscreen: function () {
	if (this.isFullScreen) {
		// 退出全屏
		this.isFullScreen = false;
		screen.exitFullscreen()
	} else {
		// 全屏展示
		this.isFullScreen = true;
		let dom = this.$refs.tablePanel.$el;
		screen.requestFullscreen(dom);
	}
}
