accessing Javacript in PDF from trigger outside of PDF Canvas

Is it possible to have a handler, located in a web page, (javascript in a CSS layer), call or trigger a function in the pdf file, (to control the animation)? Or, have the handler included in the javascipt in the CSS element control the 3D annotation?

I have successfully adapted Javascript to control the animation, and it works if placed in the pdf. But I am embedding the animation in a web page, (using embed tags), and would like to have other areas of the page call the functions, rather than need to show buttons on a pdf page.

thanks,
