vuejs开发：vue-video-player插件。
最近的项目中需要实现视频断点续播的功能，一听到这个功能。内心方张了..但却又有点小窃喜，小懵乱。抱着求学态度去挑战一下。
npm install vue-video-player --save
import VideoPlayer from 'vue-video-player'
require('video.js/dist/video-js.css')
require('vue-video-player/src/custom-theme.css')
Vue.use(VideoPlayer)
页面中应用。
<el-tree :data="ChapterOptions"
:props="defaultProps"
node-key='id'
highlight-current
:filter-node-method="filterNode"

@node-click="handleNodeClick" />
<video-player ref="videoPlayer"
class="video-player vjs-custom-skin"

:playsinline="true"

@pause="onPlayerPause($event)"

上面的 src视频地址可以换成具体的地址串,也能换成后台的地址串，因为我的是章节树所以我和章节id进行了关联。
/** 查询部门下拉树结构 */
getTreeselect() {
treeselect().then((response) => {
//封面
var img = '';
this.ChapterOptions = response.data;
for (let i = 0; i <this.ChapterOptions.length ; i++) {
this.videoName = this.ChapterOptions[0].children[0].chapterName
this.videoIntroduce = this.ChapterOptions[0].children[0].chapterIntroduce
this.VideoUrl = JSON.parse(this.ChapterOptions[0].children[0].videoAddress)
img = JSON.parse(this.ChapterOptions[0].children[0].imageAddress)
//初始化封面
for (let j = 0; j <img.length ; j++) {
this.playerOptions.poster =img[0];
}
//初始化第一个章节视频
for (let j = 0; j <this.VideoUrl.length ; j++) {
this.playerOptions.sources[0].src = this.VideoUrl[0]
}
//初始化章节
this.learningDuration.chapterId = this.ChapterOptions[0].children[0].id;
//默认高亮第一个章节节点
this.$nextTick(()=>{
this.$refs.tree.setCurrentKey(this.ChapterOptions[0].children[0].id);
})
}
});
},
// 筛选节点
filterNode(value, data) {
if (!value) return true;
return data.label.indexOf(value) !== -1;
},
// 节点单击事件
handleNodeClick(data) {
// console.log(data)
var img = '';
//刷新原视频, 原封面
this.playerOptions.sources[0].src = '';
this.playerOptions.poster = '';
//转换视频
this.VideoUrl= JSON.parse(data.videoAddress);
// console.log("this.VideoUrl")
for (let i = 0; i <this.VideoUrl.length ; i++) {
this.playerOptions.sources[0].src = this.VideoUrl[0];
}
img = JSON.parse(data.imageAddress);
for (let i = 0; i <img.length ; i++) {
this.playerOptions.poster = img[0];
}
// console.log("this.playerOptions.sources[0].src")
// console.log(this.playerOptions.sources[0].src)
//章节介绍
this.videoIntroduce = data.chapterIntroduce;
//章节名称
this.videoName = data.chapterName;
//章节id
this.learningDuration.chapterId = data.id
// console.log(this.videoIntroduce)
},
接下来就是 保存视频的进度条了，通过打印发现onPlayerTimeupdate可获取到视频的进度，故采用定时器 每3秒触发一次数据交互。
computed: {
player() {
return this.$refs.videoPlayer.player//自定义播放
}
},
mounted () {
this.timer = setInterval(this.putLearningObj, 3000)
},
destroyed () {
// 如果定时器在运行则关闭
if (this.timer) {
clearInterval(this.timer)
}
},
methods: {
putLearningObj () {
if (!this.paused) {
//保存视频进度
saveTime(this.learningDuration)
console.log('putLearningObj ~~~~~~~~~')
}
},
//当前播放位置发生变化时触发。
onPlayerTimeupdate (player) {
this.learningDuration.timeLog = player.cache_.currentTime
// console.log(' onPlayerTimeupdate!', this.timeLog)
},
},
saveTime是我自定义的与后端交互的方法。（可自行定义）
// 保存视频进度
export function saveTime(data) {
return request({
url: '/***/****/***/',
method: 'put',
data: data
})
}
那么到了这一步 进度就能保存下来了
进度恢复
想要恢复进度，就必须在视频播放前把 保存进度下来的设置到视频当中，通过打印可以看出playerReadied 可以设置
/* 设置视频进度 */
playerReadied: function (player) {
//可在此调用后台交互方法
...
player.currentTime(this.learningDuration.timeLog)
},
