vue3 + ts环境中props配置自定义类型

interface PopConfirmOptionType {
  title: string,
  confirmButtonText: string,
  cancelButtonText: string
}

// 传递给ElButton组件的属性
const props = defineProps({
  customClass: {
    type: String,
    default: ''
  },
  sync: {
    type: Boolean,
    default: false,
  },
  usePopConfirm: {
    type: Boolean,
    default: false,
  },
  popConfirmOptions: {
    type: Object as PropType<PopConfirmOptionType>,
    default: () => {
      return {
        title: "",
        confirmButtonText: "确定",
        cancelButtonText: "取消"
      }
    }
  }
});
