Configure a component and reconfigure it later

jComponent 20 · jcomponent@20 jcomponentfrontendcomponents Executed with jComponent 20

The second argument of COMPONENT() holds the default options. The config attribute of the element overrides them, and the declaration reads the merged values from config. Implement self.configure(key, value) to react when an option is set or changed. At runtime self.reconfigure('key:value;key2:value2') (or CONFIG(selector, config) for many components) changes options and calls configure for each changed key.
