FabricJS - Get Item By ID

fabric.getItem.js

fabric.Canvas.prototype.getItem = function(id) {
    var object = null,
        objects = this.getObjects();

    for (var i = 0, len = this.size(); i < len; i++) {
        if (objects[i].id && objects[i].id === id) {
            object = objects[i];
            break;
        }
    }

    return object;
};
