Question

我在redux初始状态中存储了多个值，并且我有一个动作处理程序StepOneFn，该动作处理程序正在使用组件已赋予其更改的所有值。我想更新初始状态以仅更改某些值。我不确定该怎么做。

let initial_state = {
    house_name:"",
    address:"",
    city:"",
    state:"",
    zip:0,
    img:"",
    mortgage:0,
    rent:0
}
const step_one = "step_one"

export default function reducer(state = initial_state,action){
switch(action.type){
    default:
        return state;
    case step_one:
        return {...state,...action.payload}
    }
}

export function StepOneFn(name,address,city,state,zip){
return{
    type:step_one,
    payload:{
        name,
        address,
        city,
        state,
        zip
    }
  }
}

如果您只想更改某些值，可以这样做

case step_one:
        return {...state, address:action.payload.address, city:action.payload.city}
    }

现在，它仅根据有效负载更改城市和地址，而其他不变。
