javascript - Switch Page on embedded PDF -

i want embed pdf's in webpage.

<embed id="shownpdf" style="float:left; width:1067px;height:800px;" src="../uebung12.pdf#page=1&zoom=201&scrollbar=0">pdf</embed> 

that's working pretty good.

but need 2 more features:

1. i change shownpdf when clicking on table element. have jscript function wich allows me change shown pdf
2. i need forward backward button controll shown page in pdf

i searched 2 or 3 hours now. tried:

• changing page parameter in url nothing happening.
• simulate keypress

it needs run in firefox.
