需要在mounted生命周期获取到audio或video标签

 
        mounted() {
            var els = document.querySelectorAll('audio,video')
            for (var el of els) {
                el.addEventListener('play', function (e) {
                    console.log('提示该视频正在播放中')
                    console.log(e)
                });
                el.addEventListener('pause', function (e) {
                    console.log('暂停播放')
                    console.log(e)
                })
            }
        }
 

 如果此时还是无法获取到元素或者播放暂停状态接着使用定时器

 
        mounted() {
            var aduOrVdoInterval = setInterval(function(){ 
                var els = document.querySelectorAll('audio,video')
                for (var el of els) {
                    el.addEventListener('play', function (e) {
                        console.log('提示该视频正在播放中')
                        console.log(e)
                    });
                    el.addEventListener('pause', function (e) {
                        console.log('暂停播放')
                        console.log(e)
                    })
                }
            }, 100)

        }
