reactjs - 我获取了一个数组并想将其添加到我的状态中

Question

我获取了一组对象，但无法将它们添加（或替换）到状态。

const searchSlice = createSlice({
  name: 'search',
  initialState: [],
  reducers: {
  getResults(state, action) {
     state = action.payload;
    },
   },
  });

我尝试了“state.push(action.payload)”，但结果是一个嵌套数组。“action.payload”是正确的回应。

Answer 1

由于将其推入状态会创建一个嵌套数组，

要更换，请尝试

const searchSlice = createSlice({
  name: 'search',
  initialState: [],
  reducers: {
  getResults(state, action) {
     return [...action.payload]; 
    },
   },
  });

要添加，请尝试

const searchSlice = createSlice({
  name: 'search',
  initialState: [],
  reducers: {
  getResults(state, action) {
     return [...state, ...action.payload];
    },
   },
  });
