前端开发之vue-grid-layout的使用和实例
前言
Vue Grid Layout官方文档
Vue Grid Layout中文文档
可通过拖拽改变布局（如果我们做简易开发，通过拖拽组件形成页面或者有这个需求就是非常实用的了）
因为vue-grid-layout是vue2版本的 但自己用的是vue3版本，所以要安装vue3的依赖和相关配置
效果图
一、vue中简单案例
1、安装组件
NPM
npm install vue-grid-layout --save
Yarn
yarn add vue-grid-layout
2、vue文件
<template>
<div style="width: 100%; height: 100%">
<div class="layoutJSON">
显示为
<code>[x, y, w, h]</code>
:
<div class="columns">
<div v-for="(item, indexVar) in layout" :key="indexVar">
<b> item.i </b>
: [ item.x , item.y , item.w , item.h ]
</div>
</div>
</div>
<hr />
<input v-model="draggable" type="checkbox" />
可拖动
<input v-model="resizable" type="checkbox" />
可调整大小
<input v-model="responsive" type="checkbox" />
镜像
<br />
<div style="width: 100%; margin-top: 10px; height: 100%">
<grid-layout
:col-num="12"
:is-draggable="draggable"
:is-resizable="resizable"
:layout="layout"
:responsive="responsive"
:row-height="30"
:use-css-transforms="true"
:vertical-compact="true"
>
<grid-item
v-for="(item, indexVar) in layout"
:key="indexVar"
:h="item.h"
:i="item.i"
:static="item.static"
:w="item.w"
:x="item.x"
:y="item.y"
>
<span class="text"> item.i </span>
</grid-item>
</grid-layout>
</div>
</div>
</template>
<script>
import GridLayout, GridItem from 'vue-grid-layout'
export default
components:
GridLayout,
GridItem,
,
data()
return
layout: [
x: 0, y: 0, w: 2, h: 2, i: '0' ,
x: 2, y: 0, w: 2, h: 4, i: '1' ,
x: 4, y: 0, w: 2, h: 5, i: '2' ,
x: 6, y: 0, w: 2, h: 3, i: '3' ,
x: 8, y: 0, w: 2, h: 3, i: '4' ,
x: 10, y: 0, w: 2, h: 3, i: '5' ,
x: 0, y: 5, w: 2, h: 5, i: '6' ,
x: 2, y: 5, w: 2, h: 5, i: '7' ,
x: 4, y: 5, w: 2, h: 5, i: '8' ,
x: 6, y: 4, w: 2, h: 4, i: '9' ,
x: 8, y: 4, w: 2, h: 4, i: '10' ,
x: 10, y: 4, w: 2, h: 4, i: '11' ,
x: 0, y: 10, w: 2, h: 5, i: '12' ,
x: 2, y: 10, w: 2, h: 5, i: '13' ,
x: 4, y: 8, w: 2, h: 4, i: '14' ,
x: 6, y: 8, w: 2, h: 4, i: '15' ,
x: 8, y: 10, w: 2, h: 5, i: '16' ,
x: 10, y: 4, w: 2, h: 2, i: '17' ,
x: 0, y: 9, w: 2, h: 3, i: '18' ,
x: 2, y: 6, w: 2, h: 2, i: '19' ,

二、vue3使用（vue文件）
在vue3中如果报错:
external_commonjs_vue_commonjs2_vue_root_Vue_default.a is not a constructor
1、需要导入vue3支持的该版本插件
npm add vue-grid-layout@3.0.0-beta1
2、在mian.js里引入：
import VueGridLayout from ‘vue-grid-layout’
加入：.use(VueGridLayout)
createApp(App).use(axios).use(router).use(VueGridLayout).mount(‘#app’)
因为vue-grid-layout是vue2版本的 但自己用的是vue3版本，所以要安装vue3的依赖和相关配置
三、在IE上无法打开，并报错缺少：，
主要原因就是第三方库的兼容性问题，把vue-grid-layout引入到vue.config.js文件下的transpileDependencies集合中:
module.exports =
...
transpileDependencies: ['element-ui', 'proxy-polyfill' , 'vue-grid-layout'],
VUE3 中实现拖拽和缩放自定义看板 vue-grid-layout
1. npm下载拖拽缩放库
npm install vue-grid-layout@3.0.0-beta1 --save
2. vue3 使用 vue-grid-layout报错：external_commonjs_vue_commonjs2_vue_root_Vue_default.a is not a constructor
解决方案: vue3版本记得下载对应 vue-grid-layout@3.0.0-beta1版本的库，因为vue-grid-layout是vue2版本的，但用的是vue3版本，所以要安装vue3的依赖和相关配置
3. 在main.js中注册
// 将自动注册所有组件为全局组件
import keycloakInit from '@/utils/util.keycloak'
import VueGridLayout from 'vue-grid-layout'
const app = createApp(App)
app.use(store)
app.use(router)
app.use(ElementPlus)
app.use(VueGridLayout)
app.mount('#app')4. 页面中使用组件 -- 控制保存和编辑
页面使用效果图:
点击布局进行自定义拖拽功能 ----- 效果图 ----- 箭头处可进行拖拽大小及位置:
页面代码如下:
