Class BodyOnLoadHandler

java.lang.Object
  wicket.markup.parser.AbstractMarkupFilter
      wicket.markup.parser.filter.BodyOnLoadHandler

All Implemented Interfaces:

IMarkupFilter

public final class BodyOnLoadHandler
extends AbstractMarkupFilter

If you want to package and share ready-made components and if you want this components to be easily pluggable than this component must have all the relevant information. That includes javascript (inline or referenced file) as well as CSS. With HTML these information have to be in the header of the markup return to the browser. This is true for body onLoad attributes as well. This markup inline filter detects &t;body> tags with an 'onLoad' attribute and which have no wicket:id attribute. The onLoad attribute will be copied from the component's markup to the Page's markup to allow for completely self-contained components. No changes to the Pages will be necessary to use the component.

Note: The markup must contain a <wicket:head> tag which contains the javascript and/or CSS to be copied to the Page's header.

Note: this handler is not relevant for Pages
