javascript - problems with EaselJS getCacheDataURL -

-

i have problems using getcachedataurl. function work correctly in chrome dont work in ie 10 , firefox. so:

var cont = new createjs.container(); var cont.cache(0,0,50,50); var bitmap = new createjs.bitmap(cont.getcachedataurl()); var stage = new createjs.stage(); stage.addchild(bitmap);

instead of using todataurl, use cont.cachecanvas source, creates bitmap points canvas created cache. faster exporting canvas image , using image.

var bitmap = new createjs.bitmap(cont.cachecanvas);

additionally, second line looks wrong: 

var cont.cache(0,0,50,50);

var doing nothing in context.
