文档地址：vue-grid-layout
官网介绍：
在这里插入图片描述

使用

// 安装：
npm install vue-grid-layout --save// 引用：
import { GridLayout, GridItem } from 'vue-grid-layout'// 注册：
components:{ GridLayout, GridItem }

场景

项目中，用户需要通过拖拽修改工作台布局，故使用该插件。

1.将每个模块都单独作为一个组件引入，通过 <component :is="item.components"></component>实现动态组件的加载。
2.根据设计稿，设置layout，参数解析请看gridItem 属性解析。
3.根据官网给GridLayout设置属性

实现

<template><div class="workbench-container"><grid-layout :layout.sync="layout" :use-bounds="true" :col-num="3" :row-height="100":is-draggable="true" :is-resizable="false" :is-mirrored="false" :vertical-compact="true":margin="[16, 16]" @layout-updated="layoutUpdatedEvent" :use-css-transforms="true" ref="gridRef"><grid-item class="gridItem" v-for="item in layout" :x="item.x" :y="item.y" :w="item.w" :h="item.h":i="item.i" :key="item.i"><div class="w-100 h-100 realtive grid-content"><component :is="item.components"></component><i class="del-icon" @click="delItem(item.i)"></i></div></grid-item></grid-layout></div>
</template><script>
