Can you set event.data with jquery trigger

Question

With jQuery .on() you can pass an optional parameter to set the event data. Can you do this with trigger as well?

Answer 1

In jQuery site you can see the declaration for the trigger function: .trigger( eventType [, extraParameters] )

The extraParameters must be an array or a single object and you will be allowed to get these objects with arguments[1+] (arguments[0] is equal to event object).

So, here's an example:

$('#foo').bind('custom', function(event) {
  if ( arguments.length > 1 ) {
    $.each(arguments, function(i,arg){
      alert("element " + i + " is " + arg);
    })
  }
});

$('#foo').trigger('custom', ['Custom', 'Event', { 'test' : 'attr from object' }, 123]);
