dva action一般是異步的，但是業(yè)務(wù)有時需要同步處理，總結(jié)三種處理方式如下：

1. async處理函數(shù)

  onSubmit = async (e) => {
    let params = {
         cityName: '',
        cityId: '',
    };

    this.props.dispatch({ type: 'app/loadStart' });
    try {
       await this.props.dispatch({ type: 'editDivision/updateDivisionInfo', payload: params });
      console.log('updateDivisionInfo執(zhí)行成功后，才會打印');
      this.props.dispatch({ type: 'app/loadSuccess' });

    } catch (err) {
      this.props.dispatch({ type: 'app/loadSuccess' });
    }
  }

2. 利用@@end 實(shí)現(xiàn)put的同步執(zhí)行

參考dva文檔
先執(zhí)行g(shù)etCityRank，執(zhí)行成功后，才會執(zhí)行updateInfo

     yield put({ type: 'getCityRank', payload: { cityId: 'all', employeeNo: 'all', teamId: 'all' } });
     yield take('getCityRank/@@end');

   yield put({ type: 'updateInfo', payload: { cityId: 'all', employeeNo: 'all', teamId: 'all' } });
   yield take('updateInfo/@@end');

3. promise.then

先執(zhí)行g(shù)etCityRank，執(zhí)行成功后，才會執(zhí)行updateInfo

  this.props.dispatch({ type: 'app/loadStart' });

  this.props.dispatch({ type: 'reportForm/getCityRank', payload: form }).then(() => {
      this.props.dispatch({ type: 'reportForm/updateInfo', payload: form })
      this.props.dispatch({ type: 'app/loadSuccess' });
    }).catch(() => {
      this.props.dispatch({ type: 'app/loadSuccess' });
    });
