Auto trigger button event

Hi guys,

i have a question, back in AS2 era,
if i have an MC on the stage with function as below

[COLOR=“RoyalBlue”][INDENT][INDENT]mc.onRelease = function() {
trace(“RELEASED”);
};[/INDENT][/INDENT][/COLOR]

i can actually add in another line

[INDENT][INDENT][COLOR=“RoyalBlue”]mc.onRelease()[/COLOR][/INDENT][/INDENT]

which will trigger my button event without me actually clicking on it.

I was wondering how can i achieve the same effect in as3?

because i am building a website, and i want the 1st button to trigger itself after it is
created on stage.

any idea guys?
thanks in advance

regards,
Edwin
