详解vue中在循环中使用@mouseenter 和 @mouseleave事件闪烁问题解决方法

<div class="imgs" v-for="(item,index) in exampleUrl" :key = index @mouseenter ="enterFun(index)" @mouseleave ="leaveFun(index)" >           
    <img :src = item.url v-show="show || n != index" >                
    <div  v-show="!show && n == index" >查看详情</div>
</div>

export default {
	data () {
	  return {
	    n: 0,
	    show:true,
	  }
	} ,
	methods: {
		enterFun(index){
		  console.log('鼠标移入');
		  this.show = false;
		  this.n = index;
		},
		leaveFun(index){
		  console.log('鼠标离开');
		  this.show = true;
		  this.n = index;
		},
	}    
}
