public final class CancelEventIfNoAjaxDecorator
- extends AjaxPostprocessingCallDecorator
Decorator that can be used to cancel the regular action if ajax call was performed. This allows
us to, for example, cancel the default anchor behavior (requesting href url) if an ajax call was
made in the onclick event handler. Ajax call cannot be performed if javascript has been turned
off or no compatible XmlHttpRequest object can be found. This decorator will make javascript
return true if the ajax call was made, and false otherwise.
