This little search example works but only the first time.

How do I clear all the classes from the p elements so when searching the second time, the highlight from the previous search doesn’t show?

<!DOCTYPE html>
<html>
    <head>
        <script src="http://www.google.com/jsapi" type="text/javascript"></script>
        <script type="text/javascript">
            google.load('jquery', '1.4.2');
            google.setOnLoadCallback(function() {
                $('#searchButton').click(function() {

                 //remove all added classes so we can search again
                 //jQuery.each($('p'), function() {
                    //$('#' + this).addClass('');
                 //}

                 $('p:contains("' + $('#searchText').val() + '")').addClass('highlight');
                });
            });
        </script>
        <style>
            p.highlight {
                background-color: orange;
            }
        </style>
    </head>
    <body>
        <input id="searchText" value="second" />
        <button id="searchButton">Search</button>
        <p>This is the first entry.</p>
        <p>This is the second entry.</p>
        <p>This is the third entry.</p>
        <p>This is the fourth entry.</p>
    </body>
</html>

    You can remove the highlight class on all the p then do hightlight again on matched elements. 

    $('p').removeClass('hightlight');
