基于react vant实现弹窗搜索功能

<Search

  value={value}
  onChange={setValue}
  placeholder="请输入搜索关键词"
/>

    // 开始搜索
    try {
      setSearchLoading('loading')

      const _rows = [...rows].map((item) => ({
        ...item,
        value: item.code,
        text: item.name,
      }))
      setClinicList(_rows)
      setSearchLoading('sucess')
    } catch (error) {
      setSearchLoading('sucess')
    }
}

const [clinicName, setClinicName] = useState('') // 外层业务字段
  const [searchName, setSearchName] = useState('') // 弹窗记录搜索的关键字
// 点击cell，进行选择
const setClinicHandle = (v: any) => {
    // 更新外层输入框名称
    // 关闭弹窗
    onCloseClinicPop()
}

  // loading -- 加载中，wait -- 初始化， sucess -- 搜索完成（不论结果如何）
  const [searchLoading, setSearchLoading] = useState<'wait' | 'loading' | 'sucess'>('wait')

const searchRef = useRef<SearchInstance | any>(null)
// 显示
const onShowClinicPop = () => {
    // do something 点击前校验，清空搜索关键词 onClearClinic
    setShowClinicPop(true) // 弹窗
    setTimeout(() => {

// 关闭弹窗
