So far so good but what happens when jQuery will release a new version?
You'll re download it and update your site every time?
Perhaps. Or you can add this line to your master page/layout:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>This way you reference the google hosted jquery.js file of the latest version, which is regularly updated.
You can also add the latest jQuery-ui.js file:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js"></script>What about the jQuery-ui.css?You got it!
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/pepper-grinder/jquery-ui.css" type="text/css" />
Stay updated.
