<h2 id="Summary" name="Summary">概要</h2>

<p>通过命名空间 URI 和名称来获取属性节点。</p>

<h2 id="Syntax" name="Syntax">语法</h2>

<pre class="eval"><em>attributeNode</em> = element.getAttributeNodeNS(<em>namespace</em>,<em>nodeName</em>)
</pre>

<ul>
 <li><code>attributeNode</code> 获取的属性节点.</li>
 <li><code>namespace</code> 命名空间字符串</li>
 <li><code>nodeName</code> 属性节点的名称.</li>
</ul>

<p><span class="comment">== Example == TBD The example needs to be fixed pre&gt; // html: &lt;div id="top" /&gt; t = document.getElementById("top"); specialNode = t.getAttributeNodeNS( "<a class="external" href="http://www.mozilla.org/ns/specialspace" rel="freelink">http://www.mozilla.org/ns/specialspace</a>", "id"); // iNode.value = "full-top" &lt;/pre</span></p>

<h2 id="Notes" name="Notes">笔记</h2>

<p><code>getAttributeNodeNS</code> 相比 <a href="en/DOM/element.getAttributeNode">getAttributeNode</a> 更加具体，允许你在特定的命名空间里获取属性. 对应的 setter 方法是 <a href="en/DOM/element.setAttributeNodeNS">setAttributeNodeNS</a>.</p>
