This plugin adds support for the placeholder attribute in HTML5 form elements to browsers that don't natively support it.
Just include the jquery.html-placeholder-shim.js script into your document head like so:
<head>
<script type='text/javascript' src='jquery.js'></script>
<script type='text/javascript' src='jquery/html5-placeholder-shim.js'></script>
</head>
The script will automatically execute itself on the $(document).ready event and can be re-executed at any time (for example, to add placeholders to text boxes created during dynamic changes to the page) by running $.placeholder.shim();.
<input type="search" placeholder="search the internets" name="query" />
