Associate dataURL to an image variable

[rachits123]

Hello sir,

i am using Kinetic.js to create a dynamic image with random shapes

This works fine

Later, i want to save that data generated to a image variable in a way similar to this:
img = canvas.toDataURL()

i tried to do

var image
stage.toDataURL({
callback: function(dataUrl) {
kineticdataURL = dataUrl;

image= dataURL.toDataURL

or

image =kineticdataURL

window.open(image) // i am able to see the image generated

}
});
window.open(image); // i am unable to see the image generated outside the stage.toDataURL()

all that i get is a blank screen.

Please help !!
