标题不清楚。
我使用React和Redux-toolkit。我立即在useState set函数中引用了更新后的值，但我得到的是更新前的值。我知道useState更新不是立即执行的。
1.我们要做的是，我想立即引用事件中useState的更新值。
2. summary我想重新获取事件中的列表，根据重新获取后的列表数量（multipleList.length）进行判断。
3.Code

const [ multipleList, setMultipleList ] = useState<selectAddressList[]>([])
const selAddressList = useSelectAddressList();

// ★１
useEffect(() => {
 const setNewSelAddrList = () => {
  if (selAddressList && selAddressList.length > 0){
   const newList = [...selAddressList]
  
   // It has been confirmed that the updated address list is stored here.
　 setMultipleList(newList);
　}
 }
 setNewSelAddrList();
}, [selAddressList])

// Combo Box Change Event
const onChangeAddr3 = async(rowData:string) => {

 // rowData contains a zip code.
 if (rowData != ''){

  // Get a list of addresses from a zip code
  await dispatch(fetchAsyncSelectedAddressList(rowData.toString()))        // ★２
　    
  // ★I want to be judged by the number of updated address listings.★
  if (multipleList.length == 0){
   ＸＸＸＸＸＸＸ
  }

 }
};

4. supplement ★1地址列表（selAddressList）发生变化时触发事件，通过fetchAsyncSelectedAddressList更新selAddressList。★2通过Redux的Slice，从API中获取数据，更新地址列表（selAddressList）。
   我在onChangeAddr 3中创建了一个新数组，以此类推，但无法获得更新后的列表。
   谢谢大家。
   添加代码（代码在单独的文件中. useSelector从Store）

export function useSelectAddressList():selectAddressList[] {
  return useSelector((state:RootState) => state.selectAddressList.list);
}

export const fetchAsyncSelectedAddressList = createAsyncThunk<selectAddressList[], string>(
  "address/list",
  async (zipNo : string) => {
    const res = await axios.get<selectAddressList[]>(`${url}xxxx/xxx`,{
      params: {
        zipNo: zipNo,
      } as searchParams
    });
    return res.data;
  }
);

添加代码（代码显示屏幕）

<StyleFrom>
 <NativeSelect
  required
  disabled = {disableAddress}
  value = { add3Value }
  onChange = {e => onChangeAddr3(e.target.value as string)}
 >
  <option key={0} value=''>{''}</option>
  {
   addr3List?
   addr3List.map((row) => {
    return (
     <option key={row.zipNo}
             value={String(row.zipNo)}>
      {row.addrC}
     </option>
    )
   })
  : <option key={-1} value={0}>{'Failed'}</option>}
 </NativeSelect>
