Client-side query term highlighting demo using jQuery

Here's a quick client-side query term highlighting demo that uses jQuery to parse the document.referrer and walks the DOM to highlight text by wrapping it in a <span> with the class "qterm".

Simulate search for "lorem ipsum" ... (you will need to click this link twice)

Here's the jQuery code that implements this:

<style type="text/css"> .qterm { color: #444; background-color: #ee9; font-weight: bold; } a span.qterm { color: #00f; text-decoration: underline; } a:hover span.qterm { color: #666; } </style> <script language="JavaScript"> $(document).ready(function() { if (!document.referrer) return; var matches = document.referrer.match(/[?&]q=([^&]*)/); if (!matches) return; var terms = unescape(matches[1].replace(/\+/g, ' ')); var re = new RegExp().compile('(' + terms + ')', 'i'); $("body *").each(function() { if ($(this).children().size() > 0) return; if ($(this).is("xmp, pre")) return; var html = $(this).html(); var newhtml = html.replace(re, '<span class="qterm">$1</span>'); $(this).html(newhtml); }); }); </script>
