Canvas fabric.js?

Question

Canvas

fabric.js is used ) you need to set the background of the canvas of the image that is currently transferred ) the transfer was implemented using jquery ui )but the background is not set )here is the code -
$(".move1 img").draggable({
cursor:'move' ,
helper:'clone',
appendTo:'body'
});
$('#js-left-canvas , #js-right-canvas').droppable({
drop: handleDropEvent
});
function handleDropEvent( event, ui ) {
var draggable = ui.draggable;
// var timg = draggable.currentSrc;
var timg = draggable[0];
var timg = timg.src;
var canvas = new fabric.Canvas('c');
fabric.Image.fromURL(timg , function(img) {
canvas.add(img);
});
}
I also take off the screenshots from the last question - so that it can be seen that there are two canvas tags
, at first I hung stupidly through css on the canvas that is the second one) but of course there was a problem)) that the drawing was under the image that was transferred
