ts: Property ‘resetFields’ does not exist on type 'Ref

背景：ts + vue3 + element plus
根据element plus 官方文档校验规则

// before 
import type {
    
     FormInstance } from 'element-plus'
const menuRef = ref<FormInstance>()
function reset() {
    
    
  form.value = initFormData();
   if (!menuRef) return
   menuRef.resetFields()
}

// after 
import type {
    
     FormInstance } from 'element-plus'
const menuRef = ref<FormInstance>()
function reset() {
    
    
  form.value = initFormData();
   if (!menuRef) return
   // ref变量需要使用value
   menuRef.value?.resetFields()
}
