javascript in the webrowser for security reasons doesn't have the ability to do something low level like take a screenshot of the users screens. You can take a screenshot with something like selenium

Marwan is right. Security issues prevent that for javascript. I would send a request to server with will generate the pic, and then send back the image. This of course increases the CPU & network usage of your server.

You might want to look at HTML 2 Canvas which can render some parts of the DOM into a canvas. However, this might only work on in a browser allowing you to use canvas objects as they are part of the HTML5 specification.

you can't do it with JS, generally can't make any screenshots.
