直接通过计算属性修改即可

	
	<img :src = "playStyle">
	
	//写法1
	const playStyle   = computed(()=> 
	playing.value ?require(`@/assets/img/player/play.svg`)
	:require(`@/assets/img/player/stop.svg`) )
    
    //写法2
	computed:{ 
		
		playStyle(){ 
			
		根据某个变化的值变换不同src值---->动态修改src只能用require	
			return changeValue?	require(img1):require(img2)
		}

	}
