vue3和ant-design-vue的＜a-form＞表单自定义规则校验封装

<template>

<div class="container">

//使用ant-design-vue里面的rules属性增加校验
   <a-form
            :model="formState"
            :label-col="labelCol"
            :wrapper-col="wrapperCol"
            ref="formRef"
            :rules="formRules"
            hideRequiredMark="true"
            :getContainer="() => $refs.formBox"
          >
//a-form-item外面包裹  a-row 和 a-col 是为了利用其调整每个表单元素的距离
           <a-row>
              <a-col :span="22">
                <a-form-item
                  label="名字"
                  :wrapper-col="{ span: 18 }"
                  name="name"
                >
                  <a-input v-model:value="formState.name" />
                </a-form-item>
              </a-col>
            </a-row>

           <a-row>
              <a-col :span="22">
                <a-form-item
                  label="年龄"
                  :wrapper-col="{ span: 18 }"
                  name="age"
                >
                  <a-input v-model:value="formState.age" type="textarea" />
                </a-form-item>
              </a-col>
            </a-row>

          </a-form>

</div>

<script setup>

const formState = reactive({
  name:'',
  age: "",

const formRules = {

   //validator  自定义校验
   validator:validateName,
   trigger:'change'

    }
  ]

</script>





//rule.js  自定义校验封装的文件
export async function  validateAge(rule,value) {
    let three = /^[0-9.,-]+$/;
    if (value == "") {
      return Promise.reject("请输入必填项");//返回错误校验提示
    } else if (!three.test(value)) {
      return Promise.reject("不能输入非数字");
    }
      else {
        return Promise.resolve()//正确校验通过
    }
}
export async function validateName(rule,value) {
    if(value == '') {

    }else {
