Luffy之课程详情页

Luffy之课程详情页

提前写好课程详情的template,并放入到Vue中

注册路由

import CourseDetail from "../components/CourseDetail"

    {
name:"CourseDetail",
path: "/detail",
component: CourseDetail,
}

在页面中引入vue-video组件实现视频播放

# 1. 安装依赖
npm install vue-video-player --save # 2. 在main.js中注册加载组件
require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);

在课程详情页中的script标签里面加入以下代码:

import {videoPlayer} from 'vue-video-player';

export default {
data () {
return {
playerOptions: {
playbackRates: [0.7, 1.0, 1.5, 2.0], // 播放速度
autoplay: false, //如果true,则自动播放
muted: false, // 默认情况下将会消除任何音频。
loop: false, // 循环播放
preload: 'auto', // 建议浏览器在<video>加载元素后是否应该开始下载视频数据。auto浏览器选择最佳行为,立即开始加载视频(如果浏览器支持)
language: 'zh-CN',
aspectRatio: '16:9', // 将播放器置于流畅模式,并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字(例如"16:9"或"4:3")
fluid: true, // 当true时,Video.js player将拥有流体大小。换句话说,它将按比例缩放以适应其容器。
sources: [{
type: "video/mp4",
src: "http://img.ksbbs.com/asset/Mon_1703/05cacb4e02f9d9e.mp4" //你的视频地址(必填)
}],
poster: "../static/courses/675076.jpeg", //视频封面图
width: document.documentElement.clientWidth,
notSupportedMessage: '此视频暂无法播放,请稍后再试', //允许覆盖Video.js无法播放媒体源时显示的默认信息。
}
}
},
components: {
videoPlayer
},
methods: {
onPlayerPlay(player) {
alert("play");
},
onPlayerPause(player){
alert("pause");
},
},
computed: {
player() {
return this.$refs.videoPlayer.player
}
}
}

最后前端向后端发送数据请求就可以了,后端提供数据接口
