  <p>also I'm just start learning backbone, please help me review my code any suggestion will be appreciate. </p>
  
  <pre><code>var Core = function() {
  
      var Router = Backbone.Router.extend({
          routes: {
              '': 'func0', // root/article
              'page/:id': 'func1' // root/article/page/:id
          },
          func0: function(p0) {  // ajax send fragment load data

      var Next = Backbone.View.extend({
          el: '.next',
          events: {
              'click': 'onClick'
          },
          onClick: function() {
              // console.log(Backbone.history.fragment); 
              // fragment to Backbone.history.navigate('page/'+fragment, {trigger: true, replace: true});
  
              // for example

              var router = new Router();
              Backbone.history.start({pushState: true, hashChange: false, root: '/root/public/article/'});
  
              var next = new Next();
          }
      }
