vue3弹出层V3Popup实例详解

时间:2021-10-22 15:13:26

Vue3-Popup 基于vue3构建的手机端自定义弹层组件。

一款集合了msg、alert、dialog、modal、actionSheet、toast等多种效果的Vue3自定义弹层组件。支持上下左右弹出、圆角、自定义弹层样式、多按钮及长按/右键功能。

vue3弹出层V3Popup实例详解

引入v3popup

// 在main.js中全局引入
import { createApp } from "vue"
import App from "./App.vue"
 
// 引入弹窗组件v3popup
import V3Popup from "./components/v3popup"
 
createApp(App).use(V3Popup).mount("#app")

调用方式支持标签式+函数式,根据项目需要选择合适的调用方法。

<!-- 提示框 -->
<v3-popup v-model="showMsg" anim="fadeIn" content="msg提示框测试(3s后窗口关闭)" shadeClose="false" time="3" />
 
<!-- 询问框 -->
<v3-popup v-model="showConfirm" shadeClose="false" content="<div style="color:#1be769;padding:20px;">确认框(这里是确认框提示信息,这里确认框提示信息,这里是确认框提示信息)</div>"
 :btns="[
  {text: "取消", click: () => showConfirm=false},
  {text: "确定", style: "color:#f90;", click: handleInfo},
 ]"
/>
// 函数式调用
let $el = this.$v3popup({
 title: "标题",
 content: "<div style="color:#f90;padding:10px;">这里是内容信息!</div>",
 type: "android",
 shadeClose: false,
 xclose: true,
 btns: [
  {text: "取消", click: () => { $el.close(); }},
  {text: "确认", style: "color:#f90;", click: () => handleOK},
 ],
 onSuccess: () => {},
 onEnd: () => {}
})

vue3弹出层V3Popup实例详解

vue3中可通过vue3弹出层V3Popup实例详解 和vue3弹出层V3Popup实例详解

 两种方式挂载类似vue2中prototype原型链方法。

通过 vue3弹出层V3Popup实例详解方式挂载。

// vue2中调用
methods: {
 showDialog() {
  this.$v3popup({...})
 }
}
 
// vue3中调用
setup() {
 // 获取上下文
 const { ctx } = getCurrentInstance()
 ctx.$v3popup({...})
}

通过vue3弹出层V3Popup实例详解 方式挂载。

// vue2中调用
methods: {
 showDialog() {
  this.v3popup({...})
 }
}
 
// vue3中调用
setup() {
 const v3popup = inject("v3popup")
 
 const showDialog = () => {
  v3popup({...})
 }
 
 return {
  v3popup,
  showDialog
 }
}

vue2.x中通过Vue.extends扩展函数实例来实现挂载弹窗到body上。

vue3.x中则可以通过 vue3弹出层V3Popup实例详解 和 vue3弹出层V3Popup实例详解  vue3弹出层V3Popup实例详解 来实现挂载到body上。

import { createApp } from "vue"
import PopupConstructor from "./popup.vue"
 
let $inst
// 创建挂载实例
let createMount = (opts) => {
 const mountNode = document.createElement("div")
 document.body.appendChild(mountNode)
 
 const app = createApp(PopupConstructor, {
  ...opts, modelValue: true,
  remove() {
   app.unmount(mountNode)
   document.body.removeChild(mountNode)
  }
 })
 return app.mount(mountNode)
}
 
function V3Popup(options = {}) {
 options.id = options.id || "v3popup_" + generateId()
 $inst = createMount(options)
 
 return $inst
}
 
V3Popup.install = app => {
 app.component("v3-popup", PopupConstructor)
 // app.config.globalProperties.$v3popup = V3Popup
 app.provide("v3popup", V3Popup)
}

这样就可以实现函数式来调用组件了。

另外vue2.x中给v-model传值 this.$emit("input", false)

vue3中modelValue是默认的。 则是 context.emit("update:modelValue", false)

如果定义的是v-model:visible,则需要先在props: { visible: Boolean }中声明,然后context.emit("update:visible": false)

Ok,基于vue3.0开发自定义弹框组件就介绍到这里。感兴趣的可以动手去试试哈
