假设我需要来自3个不同归约器的3个数据。
总的来说我可以做这样的事情！！

const data1 = useSelector((state: any) => state?.reducer1);
const data2 = useSelector((state: any) => state?.reducer2);
const data3 = useSelector((state: any) => state?.reducer3);

那么，如何使用单个useSelector实现相同的结果呢

reactjs

const dataState = useSelector((state: any) => ({reducer1: state?.reducer1, reducer2: state?.reducer2, reducer3: state?.reducer3}));

const data1 = dataState.reducer1;
const data2 = dataState.reducer2;
const data3 = dataState.reducer3;

您可以使用状态的解构赋值，例如：

const { reducer1, reducer2, reducer3 } = useSelector((state: any) =>
  ({
    reducer1: state?.reducer1,
    reducer2: state?.reducer2,
    reducer3: state?.reducer3
  }));
