<p class="arguement"><strong>target</strong>A selector, element, HTML string, or jQuery object; the matched set of elements will be inserted at the beginning of the element(s) specified by this parameter.</p>
</li></ul>
<div class="longdesc">
<p>The <code><a href="/prepend">.prepend()</a></code> and <code>.prependTo()</code> methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target. With<code> .prepend()</code>, the selector expression preceding the method is the container into which the content is inserted. With <code>.prependTo()</code>, on the other hand, the content precedes the method, either as a selector expression or as markup created on the fly, and it is inserted into the target container.</p>
<p>Consider the following HTML:</p>
<pre><h2>Greetings</h2>
<div class="container">
<div class="inner">Hello</div>
<div class="inner">Goodbye</div>
</div></pre>
<p>We can create content and insert it into several elements at once:</p>
<pre>$('<p>Test</p>').prependTo('.inner');</pre>
<p>Each inner <code><div></code> element gets this new content:</p>
<pre><h2>Greetings</h2>
<div class="container">
<div class="inner">
<p>Test</p>
Hello
</div>
<div class="inner">
<p>Test</p>
Goodbye
</div>
</div></pre>
<p>We can also select an element on the page and insert it into another:</p>
<pre>$('h2').prependTo($('.container'));</pre>
<p>If an element selected this way is inserted elsewhere, it will be moved into the target (not cloned):</p>
<pre><div class="container">
<h2>Greetings</h2>
<div class="inner">Hello</div>
<div class="inner">Goodbye</div>
</div></pre>
<p>If there is more than one target element, however, cloned copies of the inserted element will be created for each target after the first.</p>
</div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Prepends all spans to the element with the ID "foo"</span></h4>
<pre class="prettyprint"><code class="example demo-code"><!DOCTYPE html>
<html>
<head>
<style>div { background:yellow; }</style>
<script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
<div id="foo">FOO!</div>
<span>I have something to say... </span>
<script>$("span").prependTo("#foo"); // check prepend() examples</script>
</body>
