Can I trigger multi events in trigger() or chain them in JQuery!? E.g:
$(element).trigger('event1 event2 event3');
or
$(element).trigger('event1').trigger('event2');
or
$(element).trigger('event1');
$(element).trigger('event2');
-
I'm sure the lastest jQuery supports event queuingPhil Helix– Phil Helix2011-02-19 11:00:07 +00:00Commented Feb 19, 2011 at 11:00

As other answers note, the best built-in method is:
$(element).trigger('event1').trigger('event2');
However, I find that if you're doing this all over the place, a simple plugin cleans it up quite nicely, allowing the space-separated syntax (like other jQuery methods). Here's a quick example of such a plugin:
$.fn.triggerAll = function(events) {
if(!events) return this; //don't blow up if .triggerAll() without params
var self = this; //keep a reference
$.each(events.split(" "), function(i, e) { self.trigger(e); });
return this;
};
Then you can call it with space-separated event names, like this:
$(element).triggerAll('event1 event2 event3');
Comments
$(element).trigger('event1 event2 event3');
is not supported.
(element).trigger('event1').trigger('event2');
is optimal over
$(element).trigger('event1');
$(element).trigger('event2');
as you are not rebuilding the jQuery object containing $(element) each time you trigger an event.
