event.namespace Example Objects  <<  Top

Contains the value of the namespace specified on event triggering.

In the example below when you enter or leave the 'div2' element the mouseenter and mouseleave JavaScript events fire but the namespace isn't passed across in the event so is undefined.

When we press the left button we trigger the mouseenter JavaScript event manually and the event.namespace parameter gets passed in the object and is output as part of the message.

$(function(){
  $('#div2').on({
     'mouseenter.ns1': function(event) {
       $(this).css({backgroundColor: 'orange', color: 'black'})
              .append('**entering "div2. " Namespace: ' + event.namespace);
     },
     'mouseleave.ns2': function(event) {
       $(this).css({backgroundColor: 'green', color: 'white'})
              .append('**leaving "div2. " Namespace: ' + event.namespace);
     }
  });

  $('#btn5').on('click', function(){
     $('#div2').trigger('mouseenter.ns1');
  });
});
