I want to click on button 2 to trigger a click event on button 1.
However, when I try the following, nothing happens when clicking on #2: no alert for #1 or #2.
HTML:
<div id="container">
<button id="button-1">Button 1</button>
<button id="button-2">Button 2</button>
</div>
JS:
$('#container').on( "click", '#button-1', function(e){
alert('CLICKED 1');
});
$('#container').on( "click", '#button-2', function(e){
$('#button-1').trigger(e);
alert('CLICKED 2');
});

Moreover, if I put the #2 alert before the trigger, I end up with an infinite loop.

Why is this not working as expected?
UPDATE:
I should have made it clear: the original event must be passed. In essence, we're trying to do what was done here, but with delegated events
Use
$('#button-1').trigger('click');
or
$('#button-1').trigger(e.type);
http://jsfiddle.net/8RnBf/17/
instead of
$('#button-1').trigger(e);
JSFIDDLE DEMO
Read about jquery .trigger() here
To properly trigger a delegated event you have to create an event object and pass it to trigger()
$('#container').on( "click", '#button-2', function(e){
var event = jQuery.Event(e.type);
event.target = $('#button-1').get(0);
$('#container').trigger(event);
});
FIDDLE
That way you're actually triggering the event on the element it was bound to, passing the selector the delegated event handler will filter on as the event.target
, so it will fire just as it would if the element was actually clicked.
Or you could use the original event if you change the event.target
$('#container').on( "click", '#button-1', function(e){
alert('CLICKED 1');
});
$('#container').on( "click", '#button-2', function(e){
e.target = $('#button-1').get(0);
$('#container').trigger(e);
});
