Cocoscreator 动态加载预制体资源

            cc.loader.loadRes('background', function(errorMessage,loadedResource){
                if( errorMessage ) { cc.log( 'Prefab error:' + errorMessage ); return; }
                if( !( loadedResource instanceof cc.Prefab ) ) { cc.log( 'Prefab error' ); return; } 

                var newMyPrefab = cc.instantiate(loadedResource);
                var newMyPrefabScript = newMyPrefab.getComponent('prefabBackground');//获取预制体绑定脚本
            });
