使用vuetify实现全局v-alert消息通知的方法

import { ref } from 'vue'
export interface AlertInfo {
  id: string,
  type: string,
  message: string
}
export const newAlert = ref<AlertInfo>({
  id: 'alert' + 0,
  type: '',
  message: ''
})
export const alert = (type: string, message: string) => {
  newAlert.value.id = Math.random().toString()
  newAlert.value.type = type
  newAlert.value.message = message
}
export const errorAlert = (message: string) => {
  alert('error', message)
}
export const successAlert = (message: string) => {
  alert('success', message)
}
export const infoAlert = (message: string) => {
  alert('info', message)
}
export const warningAlert = (message: string) => {
  alert('warning', message)
}

<script setup lang="ts">
import { ref, watch } from 'vue'
import { type AlertInfo, newAlert } from '@/stores/alert'
// 定义 Map，存储Alert信息集合，使用Map便于删除
const alertMap = ref<Map<string, AlertInfo>>(new Map)
// 监听新Alert创建
watch(newAlert.value, () => {
  alertMap.value.set(newAlert.value.id, { ...newAlert.value })
  console.log(alertMap.value)
  deleteAlert(newAlert.value.id)
})
const deleteAlert = (id: string) => {
  console.log(id)
  setTimeout(() => {
    alertMap.value.delete(id)
  }, 3000)
}
</script>
