код редакс.
const reducer = (state = initialState, action) => {
switch (action.type) {
case CREATE_NEW_USER:
return {...state, items: state.items.concat([action.payload])}
case DELETE_USER:
return {...state, items: state.items.filter((item)=>{
return item.id !== action.payload.id;
})
}
case USER_INFO:
return {...state, activeUser: action.payload}
case CHANGE_INFO:
return {...state, items: state.items.forEach((item)=>{ // если использовать forEach получаю ошибку 1, если map то 2
if(item.id === action.payload.id){
console.log(item)
console.log(action.payload.id, item[action.payload.box], action.payload.newValue);
item[action.payload.box] = action.payload.newValue
}
})
}
default:
return state;
}
}
Экшен
export function changeInfo(item) {
return {
type: CHANGE_INFO,
payload: item
}
}
