vue3+ts中判断输入的值是不是经纬度格式

vue代码：

<template #bdjhwz="{ record }">
      <a-row :gutter="8" v-show="!record.editable">
        <a-col :span="12">
          <a-input placeholder="经度" v-model:value="record.lat" :max-length="15" @blur="latLngBlur(record, 'lat')" />
        </a-col>
        <a-col :span="12">
          <a-input placeholder="纬度" v-model:value="record.lng" :max-length="15" @blur="latLngBlur(record, 'lng')" />
        </a-col>
      </a-row>
    </template>

ts代码：

<script lang="ts" setup>
  import { ref, defineExpose, onMounted, Ref, watch } from 'vue';
  import { useMessage } from '/@/hooks/web/useMessage';
  
  const { createMessage: msg } = useMessage();

/**
   * 经纬度输入校验
   */
  const latLngBlur = (record, type = 'lat') => {
    if (record[type] && !isNaN(record[type])) {
      const num = Number(record[type]);
      const range = type === 'lat' ? { min: -180, max: 180 } : { min: -90, max: 90 };
      if (num > range.max || num < range.min) {
        msg.warn(`${type === 'lat' ? '经度' : '纬度'}格式输入有误！`);
        record[type] = '';
      }
    } else {
      msg.warn('请输入正确的数值！');
      record[type] = '';
    }
  };![在这里插入图片描述](https://img-blog.csdnimg.cn/direct/15bc44ff947a425dabb19cea15adc1b9.png)

</script>
