Head

java.lang.Object
- UIBean

public class Head extends UIBean

Renders parts of the HEAD section for an HTML file. This is useful as some themes require certain CSS and JavaScript includes.

If, for example, your page has ajax components integrated, without having the default theme set to ajax, you might want to use the head tag with theme="ajax" so that the typical ajax header setup will be included in the page.

The tag also includes the option to set a custom datepicker theme if needed. See calendarcss parameter for description for details.

If you use the ajax theme you can turn a debug flag on by setting the debug parameter to true.

Examples


<head>
<title>My page</title>
<s:head/>
</head>


<head>
<title>My page</title>
<s:head theme="ajax" calendarcss="calendar-green"/>
</head>


<head>
<title>My page</title>
<s:head theme="ajax" debug="true"/>
</head>
