ui设计的界面总是极具个性化的,要去修改插件中的视频控件的样式和布局太困难了,那就自己参照video原生事件,重写一个吧。

一、video标签的属性(props)html <video>标签 | 菜鸟教程
<video ref="videoPlayer" id="videoElement" controls autoplay :muted="isMute" width="800px" height="600px" > 您的浏览器不支持video</video>参数说明:(更多属性参照上述菜鸟教程中的video标签)
controls:默认为true,即向用户展示视频控件(如播放、暂停按钮等)autoplay:如果出现该属性,则视频在就绪后马上播放。muted:是否静音,默认为truewidth:设置视频播放器的宽度二、video视频控件的触发事件video标签支持的多媒体事件(Media Events) | 菜鸟教程
<video ref="videoPlayer" id="videoElement" controls autoplay :muted="isMute" width="100%" height="100%" @loadeddata="setVideoPoster($event)" @progress="videoProgress($event)" @pause="videoPause($event)" @play="videoPlay($event)" @timeupdate="videoTimeUpdate()" @ended="videoEnded()" @contextmenu="contextmenu"> 您的浏览器不支持video</video><button @click="handlePlay">播放</button><button @click="handlePause">暂停</button><button @click="handleMute">切换静音</button><button @click="fullScreen">全屏</button>data(){ return{ isMute: true // 默认静音 }}1、播放(onplay事件)this.$refs.videoPlayer.play();
methods:{ // 视频要开始播放时 videoPlay(e){ // ...触发该函数后视频会开始播放,我们可以做一些想做的事情,比如改变自定义播放按钮的样式等 }, // 自定义播放按钮中,触发视频的播放事件 handelPlay(){ this.$refs.videoPlayer.play(); // 会触发videoPlay()函数 }}2、暂停(onpause事件)this.$refs.videoPlayer.pause();
methods:{ // 视频要暂停播放时 videoPause(e){ // ...触发该函数后视频会暂停播放 }, // 自定义播放按钮中,触发视频的播放事件 handelPause(){ this.$refs.videoPlayer.pause(); // 会触发videoPause()函数 }}3、静音(muted属性)(1)切换静音
// 手动切换静音(点击(非拖拽)静音时,用户选择的音量不变)
handleMute() {
this.isMute = !this.isMute;
},
(2)改变音量(volume属性)
this.$refs.videoPlayer.volume = a; (a为从 0~1的数字)
// 这里用element的进度条写音量大小调节条<el-slider v-model="curVolume" :show-tooltip="false" @input="changeVolume"></el-slider>data(){ return{ curVolume: 0, // 默认音量为0 }},methods:{ changeVolume(val){ this.curVolume = val; // 由于h5规定volum的值在0-1之间,所以这里要对获取到的val做一个处理(滑块的val是从0-100) this.$refs.videoPlayer.volume = val / 100; // 音量为0的时候,video控件为静音 if ( val == 0 ) { this.isMute = true; } else { this.isMute = false; } }}4、全屏fullScreen() { this.$refs.videoPlayer.webkitRequestFullScreen();},5、播放进度条获取视频总时长(duration)
var videoObj = this.$refs.videoPlayer;
videoObj.addEventListener('canplay', () => {
this.totalT = videoObj.duration;
})
获取视频加载进度

// 获取视频加载进度videoProgress(e){ var bf = this.$refs.videoPlayer.buffered; var time = this.$refs.videoPlayer.currentTime; if ( bf.length != 0 ){ var range = 0; while( !( bf.start(range) <= time && time <= bf.end(range) ) ) { range += 1; } var loadEndPercentage = ( bf.end(range) / this.playerVideo.duration ) * 100; // 结束加载的百分比 this.persentLoad = loadEndPercentage; }},(1)父组件调用

'0' + m : m var s = parseInt(t % 60) s = s < 10 ? '0' + s : s return m + ':' + s }, }}(2)进度条组件(播放进度条 和 加载进度条)
