我在这个选择器上的过滤方法有什么问题？

Question

它总是return一个空数组。它应该只有 return 个 ID 和标题，其中 drawsTRFormIdAndTitleSelector 的 ID 是 === drawTRSelector

的 transactionRequestFormId

export const idAndTitleSelector = createSelector(
  drawTRSelector,
  drawsTRFormIdAndTitleSelector,
  (transactionRequests, idAndTitle) =>
    idAndTitle.filter(
      ({ id }) => id === transactionRequests.transactionRequestFormId
    )
);

drawTRSelector return 是一个 objects 的数组，如下所示：

[{
  id: "1",
  number: "1",
  transactionRequestFormId: "1",
}]

drawsTRFormIdAndTitleSelector return 是一个 objects 的数组，如下所示：

[{
  id: "1",
  title: "TR All Others",
}]

Answer 1

我想你想做这样的事情：

const drawTRSelectorIds = createSelector(
  [drawTRSelector],
  (items) => items.map(({ id }) => id)
);
export const idAndTitleSelector = createSelector(
  drawTRSelectorIds,
  drawsTRFormIdAndTitleSelector,
  (ids, idAndTitle) =>
    idAndTitle.filter(({ id }) => ids.includes(id))
);

What is wrong with my filter method on this selector?
