video标签：播放时触发canplay事件

<video:src="filePath"controlsv-if="filePrefix == 'mp4' || filePrefix == 'avi'"@canplay="getVideoDur()"id="myVideo"class="preview"></video>

canplay触发的方法：bind(this)用于当前监听的函数里面获取当前vue的this对象，不使用bind则this为当前的video对象

getVideoDur(){var video = document.getElementById("myVideo")video.addEventListener("timeupdate",function () {var timeDisplay;var duration;//用秒数来显示当前播放进度timeDisplay = video.currentTime;duration = video.duration;console.log("总时长的80%", duration*0.8);console.log("当前播放的时长", timeDisplay);if (timeDisplay > duration*0.8) {console.log("已超过总时长的80%");this.changeReadedStatus(this.curFileInfo)return;}}.bind(this),false);},

video的其他监听type：

//监听播放后时间变动
video.addEventListener("timeupdate", function () {})
//监听播放
video.addEventListener("play", function () {})//监听暂停 
video.addEventListener("pause", function () {})
