1. Go to the jquery website jquery.com and download the latest stable release, This is the best method for when you are developing your website (Unless you can all ways guarrantee that you will have a live internet connection).
2. or you can grab the very latest version straight from googles servers. I would propose this as the method to use for your live website.

Simply copy the code below into the head area of you html page.

1. <script src=”http://www.google.com/jsapi” type=”text/javascript”></script>
2. <script type=”text/javascript”>
3. // <![CDATA[
4. google.load("jquery", "1.3.2");
5. google.setOnLoadCallback(function() {
6. // Place your jquery span here.
7. });
8. // ]]>
9. </script>

1. $(document).ready(function() {
2. // The DOM is loaded now do stuff.
3. $("a").click(function() {
4. alert("Hello world!");
5. });
6. });

Instead the Google code menthod it is:
