The ajax head template builds upon the xhtml head template by providing additional JavaScript includes for the Dojo Toolkit, which is used by the ajax a template, ajax div template, and the ajax tabbedPanel template. It is required to use this tag, <ww:head theme="ajax"/>
, in your HTML <head>
block if you wish to use AJAX feature. The contents of head.ftl are:
{% highlight html %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/support-2-3/plugins/dojo/src/main/resources/template/ajax/head.ftl %} {% endhighlight %}
If you are having trouble getting the AJAX theme to work, you should include the above JavaScript in your page manually, changing “isDebug: false” to “isDebug: true”. This will log out debugging information directly to the screen.
Note that Dojo is configured to use the same character encoding specified in struts.xml
, typically UTF-8. For a simple example of how to use the head tag with the AJAX theme, simply do the following in your HTML:
{% highlight html %} {% remote_file_content https://raw.githubusercontent.com/apache/struts/support-2-3/apps/showcase/src/main/webapp/WEB-INF/ajax/commonInclude.jsp %} {% endhighlight %}
The above sample is from Struts trunk; for 2.0.6 you should use
<s:head debug="true"/>
