Answer 1

Seems that btn.onclick does not work. Added onclick attribute on the button in the html to fire the and edited the js a bit.

Answer 2

With your code as is, as of this reply, the main problem is that nowhere within your js code do you call/invoke draw().

But even if you did call/invoke draw() an error message would appear "ReferenceError: context is not defined", letting you know of the other issue.

This error will occur because the variable context is local to the onload handler() and draw() is outside the onload handler().

I suggest moving draw() inside of the onload handler(). You should call/invoke draw() inside of the onload handler() as well.

Btw, why do you need three onclick handlers()? You are overwriting the onclick handler() so the last one is actually invoked.
