全屏事件
下载依赖包
npm i [email protected]

// 全屏
import screenfull from 'screenfull'
const allVedio = () => {
	//获取dom元素节点来实现指定元素全屏展示
    let el = document.querySelector('.videobox')
    //screenfull.isEnabled  此方法返回布尔值，判断当前能不能进入全屏
    if (!screenfull.isEnabled) {
        return false
    }
    //screenfull.toggle 此方法是执行全屏化操作。如果已是全屏状态，则退出全屏
    screenfull.toggle(el)
}
