Examples of org.apache.wicket.ajax.AjaxEventBehavior

org.apache.wicket.ajax.AjaxEventBehavior
An ajax behavior that is attached to a certain client-side (usually javascript) event, such as click, change, keydown, etc.
Example:
```
 WebMarkupContainer div=new WebMarkupContainer(...); div.setOutputMarkupId(true); div.add(new AjaxEventBehavior("click") { protected void onEvent(AjaxRequestTarget target) { System.out.println("ajax here!"); } } 
```
This behavior will be linked to the click javascript event of the div WebMarkupContainer represents, and so anytime a user clicks this div the {@link #onEvent(AjaxRequestTarget)} of thebehavior is invoked. @since 1.2 @author Igor Vaynberg (ivaynberg) @see #onEvent(AjaxRequestTarget)
