Detecting JS support #22

Closed CMCDragonkai closed 11 years ago

CMCDragonkai commented 11 years ago

What would be a good way to detect whether the browser runs javascript? I know of course the modernizr won't run at all if JS was disabled, but does the server side library have a function to let me know whether it received data from modernizr?

Yes. If there is no JS there is a meta refresh tag that runs and sets a request var called nojs to true. Something similar happens if cookies aren't supported.

Does this happen on the first page load, or on the second page load? Because if my server side can detect it on the first page load (before output is sent), that would be great!
