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>
