Vue3通知提醒框（Notification）

article 2024/12/28 1:18:06

Vue3相关组件项目依赖版本信息

可自定义设置以下属性：

消息的标题（title），默认'温馨提示'
自动关闭的延时时长（duration），单位ms，默认4500ms
消息从顶部弹出时，距离顶部的位置（top），单位像素px，默认24px
消息从底部弹出时，距离底部的位置（bottom），单位像素px，默认24px
弹出位置（placement），可选：左上topLeft，右上topRight（默认），左下bottomLeft，右下bottomRight

调用时可选以下五个方法对应五种不同样式：

notification.value.open(info) // 默认使用
notification.value.info(info) // info调用
notification.value.success(info) // success调用
notification.value.error(info) // error调用
notification.value.warn(info) // warn调用

五种样式效果如下图：

open()调用：

info()调用：

success()调用：

error()调用：

warn()调用：

①创建通知提醒框组件Notification：

<script setup lang="ts">
import { ref, computed, watch } from 'vue'
const props = defineProps({
    title: { // 消息的标题
      type: String,
      default: '温馨提示'

    duration: { // 自动关闭的延时时长,单位ms，默认4500ms；设置null时，不自动关闭
      type: Number,
      default: 4500
    },
    top: { // 消息从顶部弹出时，距离顶部的位置，单位像素px
      type: Number,
      default: 24
    },
    bottom: { // 消息从底部弹出时，距离底部的位置，单位像素
      type: Number,
      default: 24
    },
    placement: { // 消息弹出位置，可选topLeft,topRight,bottomLeft,bottomRight
      type: String,
      default: 'topRight'
    }
  })

②在要使用的页面引入：

<script setup lang="ts">
import { ref } from 'vue'
import Notification from './Notification.vie'

const notification = ref()

function onShow (info: string) {
  notification.value.open(info) // 默认使用
}
function onInfo (info: string) {
  notification.value.info(info) // 默认使用
}
function onSuccess (info: string) {
  notification.value.success(info) // success调用
}
function onError (info: string) {
  notification.value.error(info) // error调用
}
function onWarn (info: string) {
  notification.value.warn(info) // warning调用
}
function onClose () { // 点击默认关闭按钮时触发的回调函数
  console.log('关闭notification')
}
</script>
<template>
  <div>
    <Button @click="onShow('This is a normal notification')" class="mr30">Open</Button>
    <Button @click="onInfo('This is a normal notification')" class="mr30">Info</Button>
    <Button @click="onSuccess('This is a success notification')" class="mr30">Success</Button>
    <Button @click="onError('This is a error notification')" class="mr30">Error</Button>
    <Button @click="onWarn('This is a warn notification')" class="mr30">Warn</Button>
    <Notification
      ref="notification"
      placement="topRight"
      :duration="3000"
      :top="30"
      @close="onClose" />
  </div>
</template>
<style lang="less" scoped>
