ee.Join.inner
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
傳回的聯結會將主要集合的元素與次要集合的相符元素配對。每個結果都有「primary」屬性，內含主要集合的元素，以及「secondary」屬性，內含次要集合的相符元素。如果指定 measureKey，聯結指標也會以屬性形式附加至物件。
| 用量 | 傳回 |
|---|
ee.Join.inner(primaryKey, secondaryKey, measureKey) | 加入 |
| 引數 | 類型 | 詳細資料 |
|---|
primaryKey | 字串，預設值為「primary」 | 用於儲存主要相符項目的屬性名稱。 |
secondaryKey | 字串，預設值為「secondary」 | 用於儲存次要相符項目的屬性名稱。 |
measureKey | 字串，預設值為空值 | 用於儲存聯結條件測量的選用屬性名稱。 |
