[CONF] Apache Wicket: How to add or update HTML tag attributes (page created)

[confluence]

Page Created : WICKET : How to add or update HTML tag attributes How to add or update HTML tag attributes has been created by Will Hoover (Jan 31, 2008). Content: There are three different approaches to adding or updating a Components HTML attributes. The first approach is the simplest approach which overrides the Components "onComponentTag" method. In your WebPage: ... // this can be any Component new TextField("my-text-field", myModel){ @Override protected void onComponentTag(final ComponentTag tag){ super.onComponentTag(tag); tag.put("onmouseover", "foo();return false;"); } }; ... The second decoupled approach is to use a generic AbstractBehavior. In your WebPage: ... new TextField("my-text-field", myModel).add(new AbstractBehavior(){ @Override public void onComponentTag(Component component, ComponentTag tag) { tag.put("onmouseover", "foo();return false;"); } }); ... The second decoupled approach is to use an AttributeModifier/AttributeAppender. In your WebPage: ... new TextField("my-text-field", myModel).add(new AttributeAppender("onmouseover", new Model("foo();return false;"), ";")); ...
