This sample code demonstartes how to pass a parameter to a backing bean method using JavaScript
   clientListener calls the javascript method
   serverListener is used to call the managed bean method
   (*serverListener is triggered only when AutoSubmit    or the partial submit property of the component is           enabled)

backing bean method:

This is the other way of passing parameter to backing bean

 In the clientListenerMethod of JavaScript var parameter is initialized here

sample JavaScript code to trigger the button

 function buttonListenerMethod() {
         //get a button and click it
         var proxyButton = AdfPage.PAGE.findComponentByAbsoluteId('cb1');
     
         var parameter = {city:"Manhattan", country:"US"};
         //click the button
         AdfCustomEvent.queue(proxyButton ,"customButtonEvent",parameter, true);
       }

or

One more good usecase where we can use ClientListener/ServerListener
