[英]How can I sort an array using immer?
I'm trying to add an object to an array in a reducer, and after that, I would like to sort it by date (I can try to insert in order, but I think is more or less the same effort).我正在尝试将 object 添加到减速器中的数组中,然后,我想按日期对其进行排序(我可以尝试按顺序插入,但我认为或多或少是相同的努力)。
I'm using immer to handle the reducer immutability:我正在使用 immer 来处理减速器的不变性:
const newState = produce(prevState, (draftState) => {
console.log(draftState);
draftState.status = COMPLETE;
draftState.current.entries.push(json.data);
if (json.included) draftState.current.included.push(json.included);
});
return { ...initialState, ...newState };
The console.log showed there is printing this: console.log 显示正在打印:
Proxy {i: 0, A: {…}, P: false, I: false, D: {…}, …}
[[Handler]]: null
[[Target]]: null
[[IsRevoked]]: true
So.. I don't really know how can I sort the draftState.current.entries
array using immer.所以.. 我真的不知道如何使用 immer 对
draftState.current.entries
数组进行排序。
Any suggestions are welcome,欢迎任何建议,
Thanks谢谢
I ended up sorting the array first and then assigning that ordered array to draftState.current.entries
我最终先对数组进行排序,然后将该有序数组分配给
draftState.current.entries
let sortedEntries = prevState.current.entries.slice();
sortedEntries.push(json.data);
sortedEntries.sort((a, b) => new Date(b?.attributes?.date) - new Date(a?.attributes?.date));
const newState = produce(prevState, (draftState) => {
draftState.status = COMPLETE;
draftState.current.entries = sortedEntries;
if (json.included) draftState.current.included.push(json.included);
});
return { ...initialState, ...newState };
To sort an array, without mutating the original array:要对数组进行排序,而不改变原始数组:
