如何在redux形式的cancel上更新redux先前状态的状态？

Question

在以redux形式取消时，如何在redux中更新先前状态？

case LOAD_CHANGE_TYPE_LIST:
            if(state.changeTypeList.indexOf(action.data) !== -1) {
                return {...state, changeTypeList: state.changeTypeList}
            }
            return {...state, changeTypeList: [...state.changeTypeList, action.data]}



export function getscnBackup() {
    return (dispatch, getState) => {
        let {info: {Info}, InfoBackup} = getState().Scn;
        let temp = {};
        temp.Description = InfoBackup.Description
        temp.TimeShipDt = InfoBackup.TimeShipDt
        temp.Reason = InfoBackup.Reason
        temp.SentDt = InfoBackup.SentDt
        temp.Nature = InfoBackup.Nature
        temp.ReslvDt = InfoBackup.ReslvDt
        temp.Comment = InfoBackup.Comment
        Info = {...Info, ...temp}
        dispatch({ type: LOAD_JPN_INFORMATION, data: { Info: Info } });
        if(InfoBackup.changeTypeList && InfoBackup.changeTypeList.length) {
            for(let i = 0; i < InfoBackup.changeTypeList.length; i++) {
                dispatch({ type: LOAD_CHANGE_TYPE_LIST, data: InfoBackup.changeTypeList[i].chgTypCode});
            }
        }
    }
 }
