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。

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" title="标题" xclose z-index="2020"
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中可通过 和
两种方式挂载类似vue2中prototype原型链方法。
通过 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 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 和 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。💪🏻
