在您的代码中，如果您已经有r[id]，则没有分配其余值.因此，请像这样更改它:

In your code, if you already have a r[id], you didn't assign the rest values. So change it like this:

const result = Object.values(
  array.reduce((r, { data }) => {
    Object.entries(data).forEach(([id, { ...el }]) => {
      r[id] = {
        ...r[id], // this is the point
        id,
        ...el
      };
    });
    return r;
  }, {})
);
