我正在嘗試為使用 Redux 操作的用戶獲取一些統(tǒng)計(jì)信息和問(wèn)題，并將其傳遞給 React 組件。問(wèn)題是，我有一個(gè) objects 數(shù)組，curPageExercisesMarked用于頁(yè)面的分頁(yè)，但它不采用我分配給它的值。奇怪的是 Redux 商店中的其他字段得到了更新，但沒(méi)有這個(gè)。我嘗試在動(dòng)作中安慰對(duì)象，但它只是打印這個(gè)：重要的是要提到我在另一個(gè)動(dòng)作中做類似的事情，使用完全相同的分配，它在那里工作。我已經(jīng)失去了一個(gè)小時(shí)試圖弄清楚這件事，所以歡迎任何幫助。Redux 操作：export const setStatistics = (problems,problemsSolved,filter = '') => dispatch => {let payload = {subject1: 0,subject2: 0,subject3: 0,total: 0,exercisesMarked: [],curPageExercisesMarked: []};for (let i = 0; i < problems.length; i++) {  if (problems[i].S === '1' && problemsSolved.includes(problems[i]._id)) {   payload.subject1++;   payload.total++;   payload.exercisesMarked.push(problems[i]);  } else if (   problems[i].S === '2' &&   problemsSolved.includes(problems[i]._id)  ) {   payload.subject2++;   payload.total++;   payload.exercisesMarked.push(problems[i]);  } else if (   problems[i].S === '3' &&   problemsSolved.includes(problems[i]._id)  ) {   payload.subject3++;   payload.total++;   payload.exercisesMarked.push(problems[i]);  } } payload.curPageExercisesMarked = payload.exercisesMarked.slice(0, 10); dispatch({  type: SET_USER_STATISTICS,  payload });};redux 減速器：export default function(state = initialState, action) {const { type, payload } = action;switch (type) {case SET_USER_STATISTICS:  return {    ...state,    exercisesMarked: payload.exercisesMarked,    curPageExercisesMarked: payload.curPageExercisesMarked,    subject1: payload.subject1,    subject2: payload.subject2,    subject3: payload.subject3,    total: payload.total  }; case CHANGE_PAGE_MARKED:  return {    ...state,    page: payload,    curPageExercisesMarked: state.exercisesMarked.slice(      (payload - 1) * state.pages_count,      payload * state.pages_count    )  }; default:  return state; }}這是不起作用的部分： payload.curPageExercisesMarked = payload.exercisesMarked.slice(0, 10);
