Tag jsValueChangeListener
Value change listener on client side.
This component replicates the 'Value Change Listener' functionality on the client side. It can be used
when the user would like a change in the value of one control to trigger off changes in the states of
other controls. One or more Javascript Listeners can be nested within the source control (a control
belonging to the 'javax.faces.Input' family). When the value of the source control is modified, the
listeners are triggered and the states of the target controls modified.
Unless otherwise specified, all attributes accept static values or EL expressions.
