<p><span class="seoSummary"><code>Element.getAttributeNames()</code> 返回一个</span>{{jsxref("Array")}}<span class="seoSummary">，该数组包含指定元素（Element）的所有属性名称，如果该元素不包含任何属性，则返回一个空数组。</span></p>

<p>将 <code>getAttributeNames()</code> 与 {{domxref("Element.getAttribute","getAttribute()")}} 组合使用， 是一种有效替代 {{domxref("Element.attributes")}} 的使用方法.</p>
