Call code with commands and EXEC

jComponent 20 · jcomponent@20 jcomponentfrontendcommands Executed with jComponent 20

Two ways to trigger code without a direct reference to the object that owns it:

A component registers a command with self.command(name, fn), and the code that holds the component instance runs it with instance.CMD(name, a, b, c) (element[0].$uicomponent is the instance of a ui-component). Use it for actions such as "open this window" or "refresh that list". The global CMD(name) is declared to reach every component, but in jComponent 20.014 it cuts a name that has no space, so it does nothing: use the instance, or EXEC().
EXEC('plugin/method', a, b) calls the method method of the plugin that lives on the path plugin; a plain function name (EXEC('myfunction')) calls a global function. The exec command of ui-bind and the exec option of many components take the same names.
