Trigger Real Event with jQuery

Question

It seems that jQuery's trigger() only runs event handlers that were bound with jQuery. I have some modules that use native browser event binding. Using the code from https://stackoverflow.com/a/2676527 works for me, but I'm wondering if there's something built in to jQuery that will do this?

Update from comments: apparently it works for click events on buttons. But not for change events on select boxes: http://jsfiddle.net/qxpXV/2/

For the record: hacking the other library to do its bindings with jQuery does make trigger() work, but I don't really want to do that.

@singpolyma What do you mean by native browser event binding? .addEventListener()? I am able to invoke such a handler: jsfiddle.net/mnrUt Hm, even if I specify the code in via an onevent HTML attribute, jQuery's .trigger() is still able to run that code: jsfiddle.net/mnrUt/1 — Šime Vidas

@ŠimeVidas - Seems it does work, always expected it to not work as the docs says it's for events bound with jQuery, and never really got around to test it ! — adeneo

@ŠimeVidas interesting that it works for click. But not for change on a select box: jsfiddle.net/qxpXV/2 — singpolyma

@singpolyma Works for me on Chrome. May be browser-specific. — user149341

You can do this by manually firing/dispatching an event (depending on the browser, fireEvent/dispatchEvent) directly on the DOM element. Code from this answer will handle the event dispatching, you'll just need to execute it against a DOM element and not the jQuery wrapper.

Accepting this because it seems to be the only way. jQuery just doesn't support this, as far as I can tell :)
