function getFilterQuery() {

const inProgressWorkState = WorkflowStates.findOne({title: 'In Progress'});
const identifiedWorkState = WorkflowStates.findOne({title: 'Identified'});
const completed = {workflowStateId: [completedWorkState._id]};

let finalQuery = {

嗨，我有一個關于 react.js 和 mongoDB 的問題。如果您在客戶端單擊完成選項，finalQuery 的控制臺日志如下所示。
finalQuery:{
archived: false
boardId: {$in: Array(0)}
createdAt: undefined listId: {$nin: Array(0)}
workflowStateId: ['ERTYUIIIIOPPCGVH']
}
理想情況下，如果用戶單擊多個選項，例如進行中或已識別，當控制臺登錄時，finalQuery 的 workflowStaeId 應如下所示。
workflowStateId: ['ERTYUIIIIOPPCGVH','asdasdasdasda','1231231dsxa']
但現在它只是被覆寫了。有誰知道如何解決這個問題？
我試圖更改代碼
if (params.completed) finalQuery = {...finalQuery, ...completed};
if (params.inProgress) finalQuery = {...finalQuery, ...inProgress};
if (params.identified) finalQuery = {...finalQuery, ...identified};
到
if (params.completed) finalQuery.push(completed);
if (params.inProgress) finalQuery.push(inProgress);
if (params.identified) finalQuery.push(identified);
但是得到一個錯誤，說 finalQuery.push 不是一個函式。
uj5u.com熱心網友回復：
您需要 concat 中的陣列finalQuery.workflowStateId，但您只使用物件擴展語法來合并物件。.workflowStateId您還必須對嵌套在更深層次的陣列使用陣列擴展語法。
if (params.completed) finalQuery = {
...finalQuery,
...{
workflowStateId:
[...(finalQuery.workflowStateId ?? []), ...completed.workflowStateId]
}
}
