vue3与elementPlus reset重置表单问题怎么解决

<template>  <div class="main">    <el-form ref="resetFormData" :model="formInline">      <el-form-item label="姓名" prop="customerName">        <el-input          v-model="formInline.customerName"          placeholder="请输入姓名"        ></el-input>      </el-form-item>      <el-button type="warning" @click="resetForm">重置</el-button>    </el-form>  </div></template>

<script>import { defineComponent, reactive, ref } from "vue";export default defineComponent({  setup() {    const resetFormData = ref(null);    const formInline = reactive({});        const resetForm = () => {      resetFormData.value.resetFields();    };    return {      resetForm,      resetFormData,      formInline,    };  },});</script>

// Vue2.0 Vue.prototype.resetForm = resetForm; //Vue3.0 let app = createApp(App); //... app.config.globalProperties.resetForm = resetForm;
