1. 先在App.vue声明全局变量

2. 在页面调用全局变量

<script>
	var app = getApp()
		
	export default {
		data() {
			return {
				musicState: true
			} 
		},
		
		onLoad() {			
			// 音频配置
			app.globalData.innerAudioContext.autoplay = true
			app.globalData.innerAudioContext.loop = true
			app.globalData.innerAudioContext.src = "https://www.xzmp3.com/down/8b3d2aa20462.mp3"					
		},
		
		onHide() {			
			this.musicState = false
			app.globalData.innerAudioContext.pause() //暂停音乐			
		},
		
		onShow() {
			this.musicState = true
			app.globalData.innerAudioContext.play() //播放音乐			
		},
		
		
		methods: {
			state(){
				if(this.musicState){
					this.musicState = false
					app.globalData.isMusic = false
					app.globalData.innerAudioContext.pause() //暂停音乐					
				} else {
					this.musicState = true
					app.globalData.isMusic = true
					app.globalData.innerAudioContext.play()	//播放音乐				
				}				
			}
		}
	}
</script>
