<h4 class="name">
<span class="versionAdded">version added: <a href="/category/version/1.0/">1.0</a></span>.siblings( [selector] )</h4>
<p class="arguement"><strong>selector</strong>A string containing a selector expression to match elements against.</p>
</li></ul>
<div class="longdesc">
<p>Given a jQuery object that represents a set of DOM elements, the <code>.siblings()</code> method allows us to search through the siblings of these elements in the DOM tree and construct a new jQuery object from the matching elements.</p>
<p>The method optionally accepts a selector expression of the same type that we can pass to the <code>$()</code> function. If the selector is supplied, the elements will be filtered by testing whether they match it.</p>
<p>Consider a page with a simple list on it:</p>
<pre>
<ul>
<li>list item 1</li>
<li>list item 2</li>
<li class="third-item">list item 3</li>
<li>list item 4</li>
<li>list item 5</li>
</ul>
</pre>
<p>If we begin at the third item, we can find its siblings:</p>
<pre>$('li.third-item').siblings().css('background-color', 'red');</pre>
<p>The result of this call is a red background behind items 1, 2, 4, and 5. Since we do not supply a selector expression, all of the siblings are part of the object. If we had supplied one, only the matching items among these four would be included.</p>
<p>The original element is not included among the siblings, which is important to remember when we wish to find all elements at a particular level of the DOM tree.</p>
