- 用命令行
npm init vue@latest新建的项目，并运行起来 -
components文件夹下新建一个文件夹hl-alert,该文件夹下新增hl-alert.vue和index.js文件，目录结构如下图
目录结构
2.1 hl-alet.vue文件中定义传入组件的属性和方法，内容如下：
<template>
<div class="base-alert" ref="hlAlert">
<div class="base-alert-bg"></div>
<div class="m-pop-content">
<img src="~@/assets/close.png" alt="" class="m-pop-close" v-if="isCloseIcon" @click="handleCancel"/>
<div class="m-pop-title" v-html="title" v-if="title"></div>
<div class="m-pop-detail">
<div v-html="message" v-if="message" class="m-pop-message"></div>
<div v-html="subMessage" v-if="subMessage" class="m-pop-submessage"></div>
</div>
<div class="g-row-flex-right g-btn-group">
<button :class="['u-base-pop-cancel', cancelBtnClass]" @click="handleCancel" v-if="!hideCancel">{{cancelBtnText}}</button>
<button class="u-base-pop-create" @click="handleOk">{{ensureBtnText}}</button>
</div>
</div>
</div>
</template>

let parent = (hlAlert.value && (hlAlert.value).parentNode) || null
if (hlAlert.value && document.body.contains(parent)) {
document.body.removeChild(parent)
}

2.2 vue2移除了vue.extend，我们使用createVNode和render来渲染弹窗
然后挂载到 config.globalProperties 上
index.js内容如下：
import {createVNode, render} from 'vue'
import HlAlert from './hl-alert.vue'
const myAlert = function(options) {
const container = document.createElement('div')
const vm = createVNode(
HlAlert,
options
)
render(vm, container)
document.body.appendChild(container)
}
const MyHlAlert = {
install(app) {
// 配置此应用
app.config.globalProperties.$hlAlert = myAlert
}
}
export default MyHlAlert
- main.js中引入弹窗组件
import { createApp } from 'vue'
import App from './App.vue'
import HlAlert from './components/hl-alert/index'
import './assets/main.css'
const app = createApp(App)
app.use(HlAlert)
app.mount('#app')
- 页面中使用
<script setup>
import {getCurrentInstance} from 'vue'
const {appContext} = getCurrentInstance()
const globalProxy = appContext.config.globalProperties
function alert () {
globalProxy.$hlAlert({
title: '审核未通过原因',
subMessage: '审核未通审核未通审核未通审核未通审核未通',
isCloseIcon: true,
cancelBtnClass: 'm-red', // 取消按钮的class
callback: () => {
console.log('确定按钮')
}
})
}
function alert2 () {
globalProxy.$hlAlert({
title: '信息提示',
subMessage: '只展示一个按钮',
isCloseIcon: true,
ensureBtnText: '确定', // 确认按钮的文字
cancelBtnText: '取消', // 取消按钮的文字
hideCancel: true // true 隐藏取消按钮
})
}
function alert3 () {
globalProxy.$hlAlert({
title: '信息提示',
subMessage: '确定按钮文字修改',
isCloseIcon: true,
ensureBtnText: '知道了', // 确认按钮的文字
cancelBtnText: '取消', // 取消按钮的文字
hideCancel: true // true 隐藏取消按钮
})
}
function alert4 () {
globalProxy.$hlAlert({
title: '信息提示',
subMessage: '<p style="text-align: left;color: red;">审核未通审核未通审核未通审核未通审核未通</p>',
isCloseIcon: true,
cancelBtnClass: 'm-red', // 取消按钮的class
callback: () => {
console.log('确定按钮')
}
})
}
</script>
<template>
<div>
<button @click="alert">click1</button>
<button @click="alert2">click2</button>
<button @click="alert3">click3</button>
<button @click="alert4">click4</button>
</div>
</template>

- 如果想把该组件发布到npm上，请参考文章 npm 发布自己写的vue3的组件
