Thanks for the tutorial – I was looking for a way to detect canvas support – perfect solution.

@Ole: I’m glad you found it useful! Stay tuned for some more elaborate examples in the coming weeks.

@Nathan Smith: Terrific suggestion, I have no idea why I didn’t implement the check in that way. It’s without a doubt cleaner and more straightforward, thanks very much for pointing it out!

Great post. Just one slight suggestion. Rather than have the entirety of the JS inside an if statement, with an else right at the end, I’d do this at the beginning…

if (!canvas.getContext) {
return;
}

That way, at a glance, you know you’ve accounted for it, instead of having to scroll all the way to the end to see what the else statement is (or to confirm that indeed there is an else statement).

Thanks for the post! I’m one of the designers who “have heard of it, but don’t quite get it”.

So i would be appreciated to read more about CANVAS and VML injection.

Keep going on :-)
