Does canvas element have “change” event?

Question

Is there a way to attach event handler to a change of a canvas element? I need to fire a function whenever something draws anything on it.

Answer 1

You could use the mouseup event.

canvasElement.addEventListener('mouseup', e => {
  // Fire function!
});

// or jQuery    
$('canvas').on('mouseup', function() {
  // Fire function!
});

The mouseup docs above actually have a good canvas example
