Javascript 如何修复react中的redux reducer和action creator？

我用redux编写了一个

onChange

函数，但它不起作用

export const changeScore = (team, value) => {
  console.log(1);
  return {
    type: ActionTypes.CHANGE_SCORE,
    payload: { team, value },
  };
};

case (ActionTypes.CHANGE_SCORE):
  console.log(2);
  return {
    ...state,
    data: state.data.map((item) => (
      item.id === action.payload.team.id
        ? { ...item, score: action.payload.value }
        : item
    )),
  };

我的action creator工作正常，但我的减速机不工作

export const changeScore = (team, value) => {
  console.log(1);
  return {
    type: ActionTypes.CHANGE_SCORE,
    payload: { team, value },
  };
};

case (ActionTypes.CHANGE_SCORE):
  console.log(2);
  return {
    ...state,
    data: state.data.map((item) => (
      item.id === action.payload.team.id
        ? { ...item, score: action.payload.value }
        : item
    )),
  };

我有

console.log（1）

但是

console.log（2）

不工作

export const changeScore = (team, value) => {
  console.log(1);
  return {
    type: ActionTypes.CHANGE_SCORE,
    payload: { team, value },
  };
};

case (ActionTypes.CHANGE_SCORE):
  console.log(2);
  return {
    ...state,
    data: state.data.map((item) => (
      item.id === action.payload.team.id
        ? { ...item, score: action.payload.value }
        : item
    )),
  };
