微信小程序（音乐）

用微信小程序做个简单的音乐

用微信小程序完成搭建后首先在app.josn的pages里加个 "pages/indexprojrct/indexprojrct"保存。

你会发现它自动跟你生成。

在indexprojrct.wxml：

<view  class="songCss"  style="flex-direction:column;">
    
    <input class="kb" placeholder="请输入歌名" name='songName' bindinput="insongname"/>
     
  <button catchtap="looksong">搜索</button>
 
<view>
<audio name="{{playing.name}}" author="{{playing.author}}" src="{{playing.url}}" id="audioCtx" controls loop bindtap="isplaySong"></audio>
</view>

<view wx:for='{{songList}}' data-music="{{item}}" data-author="{{item.artists[0].name}}" bindtap="playSong">
    <text>歌名：{{item.name}}</text>
    <text>歌手：{{item.artists[0].name}}</text>
    <view class="kb"></view>
    </view>
</view>

在indexprojrct.js:

Page({

  /**
   * 页面的初始数据
   */
  data: {
    isPlay:false,
    audioCtx:{},
    playing:{
      name:'',
      url:'',
      author:''
    },//当前播放的音乐的地址
    songName: "",
    songList:[],//歌曲列表


  },
  insongname(e) {
    this.setData({
      songName: e.detail.value
    })
  },

  /**

       })
      }
    })

  isplaySong(){    
      var b= !this.data.isPlay;
      // console.log(b);
      this.setData({
        isPlay:b
      })
      if(b){

        this.data.audioCtx.play();
      }else{
        this.data.audioCtx.pause();
      }
      
    
  },

  /**
