没有网站怎么做外贸网站模板之家免费下载

1.通过 npm 或 yarn 安装 vuedraggable 库

npm install vuedraggableyarn add vuedraggable

2. 引入组件内部使用，以下代码是一个Demo，可直接复制粘贴演示

注意：因项目使用了 vant，需要安装 vant 才能正常运行

<template><div class="wrapper"><van-nav-bar title="生产订单" left-arrow @click-left="onLeftClick" /><div class="page_bg"><div style="display: flex; justify-content: center"><van-list class="list_wrap myStyle" :loading="loading" :finished="finished" @load="onLoad"><van-cell class="cell_item" v-for="(item, index) in dataList" :key="index"><span class="sign"></span><div class="mystyle"><div>销售订单：{{ item.BillNo }}</div></div><div class="table_wrap" style="z-index: 999"><draggable class="list-group" :list="item.Entries" item-key="id" group="people" @change="onChange1"><div v-for="(items, indexs) in item.Entries" :key="indexs" style="padding: 10px"><div>{{ items }}</div></div></draggable></div></van-cell></van-list><van-list style="width: 50vw; margin-right: 10px" :loading="loading" :finished="finished" @load="onLoad"><van-cell class="cell_item myCell"><van-dropdown-menu><van-dropdown-item v-model="currentValue" :options="newList" /><van-button style="position: absolute; top: 12px; right: 15px; width: 100px; height: 55px; z-index: 999999999" type="info" size="small">提交</van-button></van-dropdown-menu><div class="table_wrap" style="height: 275px"><draggable class="list-group" :list="listObj.Entries" item-key="id" group="people" @change="onChange2"><div v-for="(items, index) in listObj.Entries" :key="index" style="padding: 10px"><div>{{ items }}</div></div></draggable></div></van-cell></van-list></div></div></div>

3.友情提示，这个库使用方法其实很简单，因为看别人写的比较复杂，自己才写一个Demo 供大家理解，其实这个库中，最重要的就是这个属性 group="people" ，它决定了哪些组件可以相互拖拽，就相当于一个 key，相同 key 的可以相互拖拽。
