jQuery .on() instead of .delegate() without event

Question

Is it possible to use jquery .on() method instead of .delegate() when there is no event to be listened to?

According to the .on() documentation:

.on( events [, selector] [, data] , handler(eventObject) )

The events argument is not optional.

The use of .on()/.delegate() is for elements that are added dynamically.

Answer 1

Since .on()s purpose it to attach event-handlers to a certain element, it makes absolutely no sense to use it without an event. That's why the event parameter is required.

From the doc:

Description: Attach an event handler function for one or more events to the selected elements.

Answer 2

You can use custom events:(it IS still an event, but YOUR event )

markup:

<div id='mePlease'>
 <div id='noWay'>Hi</div>
</div>

$('#mePlease').on('wacky','#noWay',function(){
   alert('wackyEnough');
});
$('#noWay').trigger('wacky');

but really, this could be done with a simple function call.

Answer 3

The purpose of these functions is to delegate functionality to events; so no, you can't omit the events parameter from either of these function calls.

I suspect what you want is to "do stuff" to some elements that are loaded after page-load (asynchronously), no? Maybe you also need to do this stuff to elements that already exist on page-load?

In that case I suggest you wrap your declarations in a function, and call that function both on page-load and once the asynchronous call is complete.
