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

<p>返回当前窗口，一个类数组对象，列出了当前窗口的所有直接子窗口。</p>

<h2 id="Syntax" name="Syntax">语法</h2>

<pre class="eval"><em>frameList</em> = window.frames;
</pre>

<ul>
 <li>frameList是一个frame对象的集合，它类似一个数组，有length属性且可以使用索引（[i]）来访问。</li>
 <li><code>frameList === window</code> 计算结果为true。</li>
 <li>在window.frames类数组中的每一项都代表了窗口对应给定对象的&lt;frame&gt;或&lt;iframe&gt;的内容，而不是(i)frame DOM元素（即window.frames[ 0 ]与document.getElementsByTagName( "iframe" )[ 0 ].contentWindow是相同的）。</li>
 <li>有关返回值的更多详细信息，请参考 <a class="external" href="http://groups.google.com/group/mozilla.dev.platform/browse_thread/thread/5628c6f346859d4f/169aa7004565066?hl=en&amp;ie=UTF-8&amp;oe=utf-8&amp;q=window.frames&amp;pli=1" title="http://groups.google.com/group/mozilla.dev.platform/browse_thread/thread/5628c6f346859d4f/169aa7004565066?hl=en&amp;ie=UTF-8&amp;oe=utf-8&amp;q=window.frames&amp;pli=1">thread on mozilla.dev.platform</a> 。</li>
