title: How to retrive Json data from cookie in javascript?
body: <p>This is a add to cart to cookies, but i am not clear this one, also when i click refresh and addtocart onclick function, all cookie value will be overwrittened,</p>
  
  <p>my aimed solution is, 
  cookievalue = [{id:1,price:33,qty:1},{id:1,price:33,qty:1},{id:1,price:33,qty:1}]; </p>
  
  <p>var cartstring = {};
          var jsonstring = [];</p>
  
  <pre><code>var addtocart = (function(id,price,qty)
  {
          cartstring.id = id;
          cartstring.price = price;
          cartstring.qty = qty;
          /* Also check here whether the cookie having data then the new value will be pushed and then inserted to cookie */
          jsonstring = JSON.stringify(cartstring); 
  
          var d = new Date();
          d.setTime(d.getTime() + (3600 * 24 * 60 * 60 * 1000));
          var expires = "expires="+d.toUTCString();
          document.cookie = "cartObj=" + jsonstring + ";" + expires + ";path=/";
  });
  </code></pre>
