本文小编为大家详细介绍“VUE3中如何实现拖拽与缩放自定义看板”，内容详细，步骤清晰，细节处理妥当，希望这篇“VUE3中如何实现拖拽与缩放自定义看板”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。
1. npm下载拖拽缩放库
npm install vue-grid-layout@3.0.0-beta1 --save2. 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:
属性 GridLayout参数 和 GridItem参数 官网有详细介绍
