Nodom

Employment/Purpose

The Nodom component in ZK is a server-side Java object that does not render any DOM elements or JavaScript widgets at the client-side. Instead, it renders comment nodes for positioning. This makes it ideal for controlling a group of components without introducing unnecessary DOM elements. You can use the Nodom component as the outermost container to group components under a controller (such as a composer or ViewModel) instead of using a Window or a Div.

Limitations

  • The Nodom component does not support using hflex or vflex properties within itself and its children components.

Example

Nodom Example

In the following example, the Nodom component is used as the outermost container to group components under a ViewModel. The example includes a button component inside a window and another button component inside a div.

<nodom viewModel="@id('vm')@init('foo.MyViewModel')">
	<window border="normal">
		<button id="btn" label="@init(vm.label)" />
	</window>
	<div>
		<button id="btn" label="@init(vm.label)" />
	</div>
</nodom>

public class MyViewModel {

  public String getLabel() {
		return "button";
  }
}
