<p>在返回时，sets 是一个可用的样式表集的列表。</p>

<h2 id="Example" name="Example">Example</h2>

<p>Given an {{HTMLElement("ul")}} (list) element with the ID "sheetList", you can populate it with the names of all the available style sheet sets with code like this:</p>

<pre class="brush:js">var list = document.getElementById("sheetList");
var sheets = document.styleSheetSets;

list.innerHTML = "";

for (var i = 0; i &lt; sheets.length; i++) {
  var item = document.createElement("li");

  item.innerHTML = sheets[i];
  list.appendChild(item);
}</pre>

<h2 id="Notes">Notes</h2>

<p>The list of available style sheet sets is constructed by enumerating all the style sheets available for the document, in the order in which they're listed in the {{domxref("document.styleSheets")}} attribute, adding the <code>title</code> of each style sheet that has a title to the list. Duplicates are dropped from the list (using a case-sensitive comparison).</p>
