vue列表动画

主要样式style

/* transition渐变出入场必写基础项 */
  .v-enter,.v-leave-to{
    opacity: 0;
    transform:translateY(80px);
  }
  .v-enter-active,.v-leave-active{
    transition: all 0.6s ease;
  }

 /* transition渐变出入场必写基础项 */
  .v-enter,.v-leave-to{
    opacity: 0;
    transform:translateY(80px);
  }
  .v-enter-active,.v-leave-active{
    transition: all 0.6s ease;
  }

/* transition 在删除列表项的同时，使剩余未删除项可同步移动对原位置填充*/
  .v-move{
    transition:all 0.6s ease;
  }
  .v-leave-active{
    position: absolute;
  }

js代码主要方法（只实现删除与添加）

add(){
          this.list.push({id:this.id,name:this.name})
          this.id=this.name=''
        },
del(i){
          this.list.splice(i,1)
        }
