V3Layer 基于vue3.0构建的多功能PC网页端d窗组件。
拥有超过10+种d窗类型、30+种参数配置，支持拖拽(自定义拖拽区域)、缩放、最大化、全屏及自定义置顶层叠等功能。
快速引入在main.js中引入v3layer组件。
import { createApp } from 'vue'import App from './App.vue'// 引入Element-Plus组件库import ElementPlus from 'element-plus'import 'element-plus/lib/theme-chalk/index.css'// 引入d窗组件v3layerimport V3Layer from './components/v3layer'createApp(App).use(ElementPlus).use(V3Layer).mount('#app')v3layer支持组件式+函数式两种调用方式。
组件式<v3-layer v-model="showDialog" title="标题内容" content="<div style='color:#f57b16;padding:30px;'>这里是内容信息！</div>" z-index="2021" lockScroll="false" xclose resize dragOut :btns="[ {text: '取消', click: () => showDialog=false}, {text: '确认', style: 'color:#f90;', click: handleSure}, ]"/> <template v-slot:content>这里是自定义插槽内容信息！</template></v3-layer>函数式let $el = v3layer({ title: '标题内容', content: '<div style='color:#f57b16;padding:30px;'>这里是内容信息！</div>', shadeClose: false, zIndex: 2021, lockScroll: false, xclose: true, resize: true, dragOut: true, btns: [ {text: '取消', click: () => { $el.close() }}, {text: '确认', click: () => handleSure}, ]});当d窗类型为 message | notify | popover，调用方法如下：v3layer.message({...})v3layer.notify({...})v3layer.popover({...})vue3.0中提供了app.config.globalProperties 或 app.provide 两种方式挂载全局函数。
如果是 app.config.globalProperties 方式创建：// vue2中调用methods: { showDialog() { this.$v3layer({...}) }}// vue3中调用setup() { // 获取上下文 const { ctx } = getCurrentInstance() ctx.$v3layer({...})}如果是 app.provide 方式创建：// vue2中调用methods: { showDialog() { this.v3layer({...}) }}// vue3中调用setup() { const v3layer = inject('v3layer') const showDialog = () => { v3layer({...}) } return { v3layer, showDialog }}参数配置v3layer支持如下30+参数灵活配置，实现各种d窗场景。

支持iframed窗类型 (type:’iframe’)。
配置 topmost:true 当前窗口会保持置顶。
ok，基于vue3.0开发pc端对话框组件就分享到这里。
希望对大家有所帮助哈！
