NamedNodeMap 介面表示了 {{domxref("Attr")}} 物件的集合。雖然 NamedNodeMap 與 {{domxref("NodeList")}} 都能如陣列一般透過索引訪問成員，但和 NodeList 不同的是，NamedNodeMap 中的成員並沒有順序。

+ +

NamedNodeMap 物件具有即時性（live），如果其內部成員（屬性節點物件）發生改變，NamedNodeMap 物件會自動更新至最新的狀態。

+ +
+

僅管被稱作 NamedNodeMap，但本介面並不是直接用來處理節點物件（{{domxref("Node")}}），而是專門負責屬性節點物件（{{domxref("Attr")}}）。屬性節點是一種特殊的節點，在部分瀏覽器實作中依然存在。
