本文实例为大家分享了关于Player播放器组件的具体内容，供大家参考，具体内容如下

迷你播放器：

1.播放器组件会在各个页面的情况下会打开。首先在vuex state.js 中定义全局的播放器状态

import {playMode} from 'common/js/config.js';

const state = {
 singer:{}, 
 playing:false, //是否播放
 fullScreen:false, //是否全屏
 playList:[], //播放列表
 sequenceList:[], // 非顺序播放列表
 mode:playMode.sequence, // 播放模式（顺序0，循环1，随机2）
 currentIndex:-1, //当前播放索引
}
export default state 


---------------------------------------------
// config.js

export const playMode = {
 sequence:0,
 loop:1,
 random:2
}

2.进入播放器页面时获取播放列表数据，改变播放状态在music-list列表中打开

在song-list 组件中派发事件到父组件，传入当前歌曲的信息和索引

<li @click="selectItem(song,index)" v-for="(song,index) in songs" class="item">

------------------------------
selectItem(item,index){
 this.$emit('select',item,index)
},

在music-list 组件中接受派发事件。

<song-list :rank="rank" :songs="songs" @select="selectItem"></song-list>

3. 如果commit 多个状态在actions 里设置

import {playMode} from 'common/js/config.js'

export const selectPlay = function({commit,state},{list,index}){
 commit(types.SET_SEQUENCE_LIST, list)
 commit(types.SET_PLAYLIST, list)
 commit(types.SET_CURRENT_INDEX, index)
 commit(types.SET_FULL_SCREEN, true)
 commit(types.SET_PLAYING_STATE, true)
}

4. 在music-list 组件中用mapActions提交改变值

import {mapActions} from 'vuex'

methods:{
 selectItem(item,index){
  this.selectPlay({
  list:this.songs,
  index
  })
 },
 ...mapActions([
  'selectPlay'
 ])
 },

5.在palyer 中获取vuex 全局状态，赋值状态到相应位置（代码为完整代码，对照后面讲解慢慢理解）

<div class="player" v-show="playList.length>0">　　　　// 如果有列表数据则显示
  <div class="normal-player" v-show="fullScreen">　　//如果全屏
   <div class="background">
   <img :src="currentSong.image" alt="" width="100%" height="100%">　　　　//模糊背景图
   </div>
   <div class="top">
    <div class="back" @click="back">
    <i class="icon-back"></i>
    </div>
    <h1 class="title" v-html="currentSong.name"></h1>　　　　//当前歌曲名称
    <h2 class="subtitle" v-html="currentSong.singer"></h2>　　//当前歌手名
   </div>
   <div class="middle">
    <div class="middle-l">
    <div class="cd-wrapper">
     <div class="cd" :class="cdCls">
     <img :src="currentSong.image" alt="" class="image">　　　　//封面图
     </div>
    </div>
    </div>
   </div>
   <div class="bottom">
   <div class="progress-wrapper">
   <span class="time time-l">{{ format(currentTime) }}</span>
   <div class="progress-bar-wrapper">
    <progress-bar :percent="percent" @percentChange="onProgressBarChange"></progress-bar>
   </div>
   <span class="time time-r">{{ format(currentSong.duration) }}</span>
   </div>
     <div class="operators">
    <div class="icon i-left">
     <i :class="iconMode" @click="changeMode"></i>
    </div>
     <div class="icon i-left" :class="disableCls">
      <i @click="prev" class="icon-prev"></i>
      </div>
      <div class="icon i-center" :class="disableCls">
      <i :class="playIcon" @click="togglePlaying"></i>
      </div>
      <div class="icon i-right" :class="disableCls">
      <i @click="next" class="icon-next"></i>
      </div>
      <div class="icon i-right">
      <i class="icon icon-not-favorite"></i>
      </div>
    </div>
    </div>
   </div>
   </transition>
   <transition name="mini">
    <div class="mini-player" v-show="!fullScreen" @click="open">
     <div class="icon">
      <img :src="currentSong.image" alt="" width="40" height="40" :class="cdCls">
     </div>
     <div class="text">
      <h2 class="name" v-html="currentSong.name"></h2>
      <p class="desc" v-html="currentSong.singer"></p>
     </div>
     <div class="control">
      <i :class="miniIcon" @click.stop="togglePlaying"></i>
     </div>
     <div class="control">
      <i class="icon-playlist"></i>
     </div>
    </div>
   </transition>
   <audio :src="currentSong.url" ref="audio" @canplay="ready" @error="error" @timeupdate="updateTime" @ended="end"></audio>
 </div>
