在要使用的页面引入

其中引入使用了 Vue3按钮（Button）、Vue3全局提示（Message）

<script setup lang="ts">
import Popconfirm from './Popconfirm.vue'
import Button from './Button.vue'
import Message from './Message.vue'
import { ref } from 'vue'
const message = ref()
const confirm = (e: MouseEvent) => {
  console.log(e)
  message.value.success('Click on Yes')
}
const cancel = (e: MouseEvent) => {
  console.log(e)
  message.value.error('Click on No')
}
</script>
