第三步:页面上使用
<template> <div class="wholeList"> <draggable class="leftCon" :list="tolList" > <div class="leftConLi" v-for="element in tolList" :key="element.id"> {{ element.name }} </div> </draggable> <ul class="oneUl"> <li class="oneLi" v-for="(item,index) in tolList" :key="index" > <!--拖拽内容部分-1--> <draggable v-if="index === 0" class="dragArea list-group" :list="item.children" :clone="clone" :group="{ name: 'people', pull: pullFunction }" @start="start" > <div v-for="element in item.children" :key="element.id" class="list-group-item"> {{ element.name }} </div> </draggable> <!--拖拽内容部分-其他--> <draggable v-else class="dragArea list-group" :list="item.children" :clone="clone" group="people" > <div v-for="element in item.children" :key="element.id" class="list-group-item"> {{ element.name }} </div> </draggable> </li> </ul> <el-button @click="getNewList">点我看console里面的最新数据</el-button> </div> </template> <script> import draggable from 'vuedraggable' export default { components: { draggable }, data() { return { tolList: [ { name: '第一天', children: [ { name: '11111', id: 1 } ] }, { name: '第二天', children: [ { name: 'aaaaa', id: 11 }, { name: 'bbbbbb', id: 12 } ] }, { name: '第三天', children: [ { name: ',,,111,,', id: 21 } ] } ], controlOnStart: true } }, methods: { clone({ name, id }) { return { name, id: id } }, pullFunction() { return this.controlOnStart ? 'clone' : true }, start({ originalEvent }) { this.controlOnStart = originalEvent.ctrlKey }, getNewList() { let a = this.tolList console.log(a) } } } </script> <style lang="scss" scoped> .wholeList{ margin-top:200px; width:500px; display: flex; flex-wrap: wrap; .leftCon{ width: 100px; .leftConLi{ background: #42B974; line-height: 80px; margin-bottom:10px; } } .oneUl{ width: calc(100% - 100px); .oneLi{ display: flex; height: 80px; margin-bottom:10px; border:1px solid red; .dragArea{ width: 100%; min-height: 30px; } } } } </style>
