org.apache.cocoon.forms.datatype
Class JavaScriptSelectionListBuilder

java.lang.Object
  org.apache.cocoon.forms.datatype.JavaScriptSelectionListBuilder

All Implemented Interfaces:

Contextualizable, SelectionListBuilder

public class JavaScriptSelectionListBuilder
extends Object
implements SelectionListBuilder, Contextualizable

Builds a selection list that will take its values from a JavaScript snippet. The snippet runs in scope where the list filter (if any) and the view data are available as filter and viewData respectively, along with all flowscript functions. It must return a list of (value, label) pairs.

If an item has no label, its value is used as the label. If the declaration has a catalogue attribute, the labels are interpreted as i18n keys in that catalogue.

Example:

   <fd:selection-list type="flow-function">
     return [ {value: 3, label: "three"}, {value:4} ];
   </fd:selection-list>
