No way to tell if drawLayers has finished

Would you accept a PR that adds another function, i.e. willDrawLayers (or some other name) that returns a promise to draw the layers? Right now there is no way to tell if this function has finished, which has resulted in an issue for me. Otherwise, does drawLayers currently support callbacks? Let me know if you need further information describing my situation.

Nah, it’s still related. 😃

jCanvas stores its data for each canvas element as jQuery data (set using $.data). I believe jQuery’s clone() method will copy this data if you specify the appropriate arguments (see the withDataAndEvents and deepWithDataAndEvents parameters in the aforementioned method docs).

Alright, I’ve made a few tweaks to add support for a complete callback to drawLayers, which runs when all layers have finished drawing.

Here’s the basic usage:

$myCanvas.drawLayers({
  complete: function() {
    // code here runs when all layers have finished drawing
  }
});

You can download the updated jCanvas build below. @r0fls, please try it and let me know if it solves your particular issue. 😃
