  • You can use https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage to send a message back to the parent once the process in the iframe stops drawing – zuckerburg Jan 18 '19 at 10:28

  • the iframe and the canvas don't belong to me, so can't change their code, i can get iframe load but not canvas drawing finish. – StraightforwardDev Jan 18 '19 at 10:56
