运行环境:vue3.2以上,复制张贴运行即可看效果
效果如下:
<template> <div class="container"> <transition-group name="flip-list"> <div v-for="item in items" :key="item" draggable="true" class="items" @dragstart="dragstart(item)" @dragenter="dragenter(item)" @dragend="dragend">{{item}}</div> </transition-group> </div> </template> <script setup> import { ref } from "vue"; const items = ref([1, 2, 3, 4, 5, 6, 7, 8, 9]) const oldNum = ref(0) const newNum = ref(0) // 记录初始信息 const dragenter = (param) => { newNum.value = param } // 做最终操作 const dragend = () => { if(oldNum.value !== newNum.value){ const oldIndex = items.value.indexOf(oldNum.value) const newIndex = items.value.indexOf(newNum.value) const newItems = [...items.value] // 删除老的节点 newItems.splice(oldIndex,1) // 在列表中目标位置增加新的节点 newItems.splice(newIndex,0,oldNum.value) // items改变transition-group就会起作用 items.value = [...newItems] } } // 记录移动过程中信息 const dragstart = (param) => { oldNum.value = param; } </script> <style scoped> .items { width: 300px; height: 50px; line-height: 50px; text-align: center; background: linear-gradient(45deg, #234, #567); color: pink; } .flip-list-move { transition: transform 1s; } </style>
