当多个使用弹窗类组件，可使用这种方式封装组件。（以下使用antd-vue、vue3）

1.代码

点击查看代码

<template>
  <slot :openDialog="openDialog" :closDialog="modalCancel"></slot>

  <a-modal v-model:open="open" title="Basic Modal" @cancel="modalCancel">
    <template #footer>
      <a-button type="primary" @click="modalComfirm">确定</a-button>
      <a-button @click="modalCancel">取消</a-button>
    </template>
  </a-modal>
</template>

<script lang="ts" setup name="modalComponent">
import { ref } from 'vue';

// 弹窗
const open = ref(false);
const openDialog = () => {
  open.value = true;
};
const modalCancel = () => {
  open.value = false;
};
const modalComfirm = () => {
  open.value = false;
};
</script>

<style lang="less" scoped></style>

2.使用方式

点击查看代码

<modalBtn>
  <template #default='{ openDialog }'>
    <button @click='openDialog'>操作按钮</button>
  </template>
</modalBtn>
