Javascript switch on / off

Question

What is the best way to toggle the warning "Please enable Javascript"?

I currently have something like this:

<div id='JSwarning'>ONLY SQUARES DON'T USE JAVASCRIPT</div>

to which I then apply .style.display = "none".

This shows a warning on each page for a while until it loads. There should be a more elegant way. Can I do this using PHP?

(BTW get_browser()is not the solution I'm looking for.)

// EDIT

Thanks to everyone that does the trick. By the way, in order to check the page (XHTML 1.0 Strict), I needed to place the child element of node (s) in the block container.
