Webcam with button - best way to go? Options

[icepick]

Hi everyone,

I have a simple HTML page showing a live webcam feed. Underneath the webcam image I have a couple of links the user can push (stuff like "turn the light on" and "turn the light off" ). When the user clicks the link I want him to stay on the same page, and in the background it should call a small light-on.php script. I don't want him to leave the webpage.. all he should keep on seeing is the webcam feed.

What I do right now is I use frames.. so when he clicks the link it opens up a black page in a very small 1% frame (so the user doesn't notice it does that).. but is there a nicer way to do this?

Regards,
Alex
