Replace all Headers Tags using jQuery

Here’s a simple script that replaces all the Header Tags (H1, H2, H3) in a page

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Convert all Header Tags using jQuery</title>
    <script src="jquery-1.4.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function () {
            $("#btnConvert").click(function () {
                $("h1, h2, h3").replaceWith(function () {
                    return "<b>" + $(this).text() + "</b>";
                });
            });
        });
    </script>
</head>
<body>
 <div>
 <h1>Paragraph One starts here</h1>
 <p>This is some content of paragraph one</p>
 <h2>Paragraph Two starts here</h2>
 <p>This is some content of paragraph two</p>
 <h3>Paragraph Three starts here</h3>
 <p>This is some content of paragraph three</p>
     <input id="btnConvert" type="button" value="Convert Headers" />
 </div>       
</body>
</html>



The replaceWith(function) is a new addition in jQuery 1.4 which can return a HTML string.
