Jquery :: Loading Function Via Onload

I have a bunch of jquery code that animates survey results. It starts by clicking on a css designed 'submit button' (see below). My question is to get the following, which works once the button is submitted, to activate instantly upon page load...for reference, here is what I am working with currently:

Code:

Then a css enabled 'pop up window' appears due to a CSS effect:

Code:

Question is: How do I do this without clicking on a button. Rather, have this work, as it does now, by page onload? It'd save me a ton of time and finally let me wrap up a project where the creator parted ways.

I know one might want to ask "Why does it have to activate on onload? Take my word, having a pop up with querystring makes all the difference for reasons I won't get into.
