使用场景是这样的页面上有多个音频源，需要点击一个播放，不允许同时播放，点击一条当前就播放点击的这条音频源

给出代码

var util = require('../../utils/util.js');
const innerAudioContext = wx.createInnerAudioContext();
const app = getApp()
Component({
  /**
   * 组件的属性列表
   */

      type: Boolean
    },

      type: String
    }
  },

   * 组件的初始数据
   */

    isPlayAudio: false,
    isLoading: false,

    btnsrc: '/pages/images/ico-audio-play.svg',
    processBarWidth: "0", //百分比
    audioSeek: "00:00",
    audioDuration: 0,
  },
  /**
   * 组件的方法列表
   */
