vue组件化学习第三天

学习制作自定义组件

实例music.vue

1:首先在components文件中新建文件夹music

2：在文件music中创建music.vue，index.js，两者路径在同一级

3:index.js代码如下

 1 import Mymusic from './Music.vue'
 2 // 这里是重点
 3 const Music = {
 4     install: function(Vue){
 5         Vue.component('Music',Mymusic)
 6     }
 7 }
 8 
 9 // 导出组件
10 export default Music

4：music.vue内容如下

  1 <template>
  2     <div class="music-box" :class="musicShow?'music-box-active':''">
  3         <div class="music-title">{{song.name}}</div>
  4            <div class="music-paly">
  5                <audio id="audio">
  6               <source :src="song.src" type="audio/ogg">
  7               <source :src="song.src" type="audio/mpeg">
  8               <source :src="song.src" type="audio/mp3">
  9               您的浏览器不支持 audio 元素。
 10             </audio>
 11            </div>
 12            <div class="play-btn-pre" @click="preBtn">
 13                <i class="el-icon-arrow-up"></i>
 14            </div>
 15            <div class="play-btn" @click="play" :class="musicPlay?'music-play-active':''">
 16                <i class="el-icon-service"></i>
 17            </div>
 18            <div class="play-btn-next" @click="nextBtn">
 19                <i class="el-icon-arrow-down"></i>
 20            </div>
 21            <div class="music-btn" @click="showMusic" v-if="!musicShow">
 22                <i class="el-icon-d-arrow-left"></i>
 23            </div>
 24     </div>
 25     
 26 </template>
