To Communicate portlets by clientSide using javaScript,
Liferay Provide javascript function trigger and bind.
you can trigger a event from one portlet and send data to another 
portlet where you bind event using liferay javaScript function.

   Liferay.trigger('event-name', {parameter: 'parameter'});

• Now in another receiver portlet you have to bind the same event-name which one you have trigger from sender portlet.

      Liferay.bind('event-name',
             function(event, data){
                
                   var message = data.parameter;
        });

             Liferay.bind('event-name',
                  function(event, data){
                    var message = data.parameter;
                    var form = document.getElementById('formName');
                    var element = document.getElementById('element');//button/Link
                    var evObj=document.createEvent("MouseEvents");
evObj.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
