<ul class="signatures"><li class="signature" id="replaceAll-target">
<h4 class="name">
<span class="versionAdded">version added: <a href="/category/version/1.2/">1.2</a></span>.replaceAll( target )</h4>
<p class="arguement"><strong>target</strong>A selector expression indicating which element(s) to replace.</p>
</li></ul>
<div class="longdesc">
<p>The <code>.replaceAll()</code> method is corollary to <code><a href="/replaceWith">.replaceWith()</a></code>, but with the source and target reversed. Consider this DOM structure:</p>
<pre><div class="container">
<div class="inner first">Hello</div>
<div class="inner second">And</div>
<div class="inner third">Goodbye</div>
</div></pre>
<p>We can create an element, then replace other elements with it:</p>
<pre>$('<h2>New heading</h2>').replaceAll('.inner');</pre>
<p>This causes all of them to be replaced:</p>
<pre><div class="container">
<h2>New heading</h2>
<h2>New heading</h2>
<h2>New heading</h2>
</div></pre>
<p>Or, we could select an element to use as the replacement:</p>
<pre>$('.first').replaceAll('.third');</pre>
<p>This results in the DOM structure:</p>
<pre><div class="container">
<div class="inner second">And</div>
<div class="inner first">Hello</div>
</div></pre>
<p>From this example, we can see that the selected element replaces the target by being moved from its old location, not by being cloned.</p>
</div>
<h3>Example:</h3>
<div class="entry-examples" id="entry-examples"><div id="example-0">
<h4><span class="desc">Replace all the paragraphs with bold words.</span></h4>
<pre class="prettyprint"><code class="example demo-code"><!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
<p>Hello</p>
<p>cruel</p>
<p>World</p>
<script>$("<b>Paragraph. </b>").replaceAll("p"); // check replaceWith() examples</script>
</body>
</html></code></pre>
