How to get previous page url, not referrer in JavaScript?

Question

Here is an example.

1) I open google.com. Object looks like this:

{
  url: 'https://www.google.com/',
  previous: '',
  referrer: ''
}

2) Then I click on the link /news and the object looks like this:

{
  url: 'https://www.google.com/news',
  previous: 'https://www.google.com/',
  referrer: 'https://www.google.com/'
}

3) Then I open a new tab and go to https://stackoverflow.com/ and the object looks like this:

{
  url: 'https://stackoverflow.com/',
  previous: 'https://www.google.com/news',
  referrer: ''
}

How to achieve it? I tried with window.localStorage but it doesn't work.

Please try Backbone model, routing and HTML5 History API.

I am showing how to achieve the First Step:

    var model=Backbone.Model.extend({
     defaults:{
      url: '',
      previous: '',
      referrer: ''
     },
     get_url:function(){
       var self=this;
       self.get_url=window.location.href;
     }
    });

   var obj=new model(); //create instance of Model
   obj.set('url',obj.get_url); // set the url value to model attribute

if You want the previous Attribute value,

   obj.previousAttributes();

And Follow the same steps, set all other url attribute value to model and get the values.
