vue3-layer:基于Vue3.0开发的PC桌面端自定义对话框组件。

基于vue3构建的PC网页端自定义弹出框组件。全面覆盖各种弹窗应用场景,拥有10+种弹窗类型、30+种自定义参数配置、7+种弹窗动画效果,支持拖拽、缩放、最大化、全屏及自定义激活当前置顶层等功能。

vue3自定义dialog、modal组件的方法

前几天分享过一个Vue3.0移动端弹层组件V3Popup,如果感兴趣也可以去看看。

v3layer在开发设计之初灵感来自有赞Vant3.0、饿了么Element-Plus等组件化模式。

快速引入

在main.js中全局引入组件。

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"
 
// 引入弹窗组件v3layer
import V3Layer from "./components/v3layer"
 
createApp(App).use(ElementPlus).use(V3Layer).mount("#app")

v3layer在调用上同样支持组件式+函数式两种方式。

组件写法

<v3-layer 
 v-model="showAlert"
 content="<div style="color:#f57b16;padding:30px;">这里是内容信息!</div>"
 z-index="2030"
 lockScroll="false"
 xclose
 resize
 dragOut
 :btns="[
  {text: "取消", click: () => showAlert=false},
  {text: "确认", style: "color:#f90;", click: handleConfirm},
 ]"
/>
 <template #content>自定义插槽内容信息!</template>
</v3-layer>

 

函数写法

let $el = v3layer({
 title: "标题信息",
 content: "<div style="color:#ff5252;padding:50px;">这里是内容信息!</div>", 
 shadeClose: false,
 zIndex: 2030,
 lockScroll: false,
 xclose: true,
 resize: true,
 dragOut: true,
 btns: [
  {text: "取消", click: () => { $el.close() }},
  {text: "确认", click: () => handleConfirm},
 ]
});

遵循极简的调用原则,只需输入参数配置即可快速调用弹窗,实现想要的效果。

    shadeClicked,
    btnClicked,

  }
 }
</script>

大家如果感兴趣,可以在此基础上自行定制一些想要的效果。

另外,v3layer组件支持自定义拖拽区域 (drag:"class或id"),是否拖动到窗口外 (dragOut:true)。支持iframe弹窗类型 (type:"iframe")。

当配置 topmost:true 则会将当前活动窗口置顶显示。
