如何在React组件中更新字段的字段?

我正在尝试编写事件处理程序以更新组件中某个字段的字段。我的组件具有以下属性...


    deliveryConfirmationImage: null
    
    deliveryLocation: {address: "639 N Westmoreland Ave, Los Angeles, CA 90004, 
    
    pickUpWindow: {startTime: "2020-05-17T18:58:28.829545", timeWindowType: "whenever possible"}
    

请注意,pickUpWindow本身就是一个具有自己属性的对象。我的伴侣中有这个...

  const { handleChange, values } = useForm(mission);
...
  function handleChangePickupWindow(data) {
    const { time } = data;
    const name = "pickUpWindow";
    const value = {startTime: time};
    handleChange({ target: { name, value } });
  }

...
                <DateTimeInput
                  dateInputProps={{
                  id: "date-pickup",
                  label: "Pickup Date",
                }}
                onChange={handleChangePickupWindow}
                required
                timeInputProps={{
                  id: "time-pickup",
                  label: "Pickup Time",
                }}
                value={values.pickUpWindow.startTime}
              />

我在其中定义“ handleChange”钩子,就像这样...

  const handleChange = ({ target }) => {
    setValues((values) => ({
      ...values,
      [target.name]: target.value,
    }));
  };

但是可悲的是,尽管我看到传递给句柄更改事件处理程序的时间的正确值,但我不知道如何更新“值”对象中的相应项以正确地更新组件-即“ values.pickUpWindow”。即使我尝试对其进行更改,“ startTime”也始终保持相同的值。我还需要做些什么来更新我的基础字段?
