App.vue，增加修改css样式的代码：

  .el-checkbox__inner{
    width:16px;
    height: 16px;
    border: 1px solid #999;
  }
  .el-checkbox__inner:after{
    width: 6px;
    height: 8px;
  }
  .el-form-item__content{
    margin-left:0px!important;
    width: 120px;
  }

课程详情页

创建课程详情页的组件Detai.vue，基本代码结构：

<template>
    <div class="detail">
      <Header/>
      <div class="main">

      </div>
      <Footer/>
    </div>
</template>

<script>
import Header from "./common/Header"
import Footer from "./common/Footer"
export default {
    name: "Detail",
    data(){
      return {}
    },
    components:{
      Header,
      Footer,
    }
}
</script>

<style scoped>

</style>

在router/index.js中增加路由

import Detail from "@/components/Detail"

  // 路由规则
  routes:[
    ,{
      name:"Detail",
      path: "/detail",
      component: Detail,
    },
  ]
})

在课程列表页中的li里面新增一个router-link 跳转链接。

<template>
  <div class="course">
    <Header/>
    <div class="main">
      <!-- 筛选功能 -->
      <div class="top">
        <ul class="condition condition1">
          <li class="cate-condition">课程分类:</li>
          <li class="item current">全部</li>
          <li class="item">Python</li>
          <li class="item">Linux运维</li>
          <li class="item">Python进阶</li>
          <li class="item">开发工具</li>

          <li class="item">机器学习</li>
          <li class="item">技术生涯</li>

          <li class="item price">价格</li>
          <li class="course-length">共21个课程</li>
        </ul>
      </div>
      <!-- 课程列表 --->
      <div class="list">
        <ul>
          <li class="course-item">
            <router-link to="/detail" class="course-link">
              <div class="course-cover">...
              <div class="course-info">...               
            </router-link>
          </li>
          ...../// 省略代码
</template>


<style scoped>
.course-link{
  overflow: hidden;

使用vue-video播放器

 

线上的路飞学城使用了AliPlayer阿里播放器。

我们本次项目使用vue-video播放器，是专门提供给vue项目使用。使用只需要完成四个步骤:

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);

3.在课程详情页中的script标签配置播放器的参数,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");
    },
    player() {
      return this.$refs.videoPlayer.player
    }
  }
}

在html模板中调用video-player标签显示播放器

 <div class="warp-left" style="width: 690px;height: 388px;background-color: #000;">
            <video-player class="video-player vjs-custom-skin"
                 ref="videoPlayer"
                 :playsinline="true"
                 :options="playerOptions"
                 @play="onPlayerPlay($event)"
                 @pause="onPlayerPause($event)"
            >
            </video-player>
          </div>

效果:

 

集成了编辑器以后的课程详情页组件代码

<template>
    <div class="detail">
      <Header/>
      <div class="main">
        <div class="course-info">

               :playsinline="true"
               :options="playerOptions"
               @play="onPlayerPlay($event)"
               @pause="onPlayerPause($event)"
