在fabric.js 上如何获取活动对象上的项目（计数）

Question

How can I get the canvas.item(#) or src of active object in fabric.js. I have the following. but get_id() function returns "Layer_1" every time for any object

 function load() {
        fabric.Object.prototype.transparentCorners = false;
        fabric.loadSVGFromURL('images/test.svg', function (objects, options) {
            var shape = fabric.util.groupSVGElements(objects, options);
            canvas.add(shape.scale(1));
            shape.set({ left: 200, top: 100, ZIndex: 10 }).setCoords();
            canvas.renderAll();
        }) ; }


  function get_id() {
        var obj = canvas.getActiveObject();
        var newCanvasId = obj.id;
        alert(newCanvasId)
}

I would like to get unique id or item(#) image name or src or .... to identify this active object. any help please?
