            //sp.js has been loaded
            SP.SOD.registerSod('reputation.js', SP.Utilities.Utility.getLayoutsPageUrl('reputation.js'));
            SP.SOD.registerSod('jquery-3.2.1', '../SiteAssets/Scripts/jquery-3.2.1.min.js');
            SP.SOD.loadMultiple(['reputation.js', 'jquery-3.2.1'], function () {
                //reputation.js & jquery-3.2.1.min.js have been loaded.
                var context = SP.ClientContext.get_current();
                var web = context.get_web();
