Data Attributes

The DependsOn plug-in is based on the following data attributes:

For dependent fields:

• data-dependson - to provide Query with a condition or expression for the Action
• data-dependsonaction - (optional) to define the Action that should be executed
• data-dependsonskipinitial - (optional) a marker to disable initial execution

For referenced fields:

• data-dependsonref - to mark a field that is referenced in the Query.
• data-dependsonreftype - (optional) to define the expected type of reference value.
• data-dependsonreflazy - (marker) an attribute to mark a reference as lazy. In this case, DependsOn will not observe rapid events like input.

EToolbox Authoring Kit Annotations

• @DependsOn - to define a single DependsOn Action with the Query. Multiple annotations per element can be used.
• @DependsOnRef - to define a referenced element name and type. Only a single annotation is allowed.
• @DependsOnTab - to define a DependsOn Query with tab-visibility Action for a tab.

Debug Info

DependsOn produces three types of debug notifications:

• Critical errors: DependsOn will throw an Error on a configuration mismatch (like unknown action name, illegal custom accessor registration, etc.)
• Error messages: not blocking runtime messages (Query evaluation errors, unreachable references, etc.)
• Warn messages: potentially unexpected results warning or deprecated functionality

The following expression can be evaluated in the browser console to see current DependsOn debug information (references, actions): Granite.DependsOnPlugin.debug()
