How to use JQuery

This is a basic tutorial, designed to help you get started using jQuery. If you don’t have a test page setup yet, start by creating a new HTML page with the following contents:

[sourcecode language="plain"]<html>
  <head>
    <script type="text/javascript" src="jquery.js"></script>

    <script type="text/javascript">
     
    </script>
  </head>
  <body>
    <a href="http://jquery.com/">jQuery</a>
  </body>
</html>
[/sourcecode]

Edit the src attribute in the script tag to point to your copy of jquery.js. For example, if jquery.js is in the same directory as your HTML file, you can use:

[sourcecode language=”plain”]<script type="text/javascript" src="jquery.js"></script>[/sourcecode]
