```
$(".esc-policy  a").on('click',function(){
   var name = $("#nameInput").val(),
   description = $("#descriptionInput").val();
   $.cookie('back_to_url_onPage_referesh', 1);
   $.cookie('name',name);
   $.cookie('description',description);
});
```
If you add this code it will work as it is in your js. if you don't use cookie plugin in jquery. use native document.cookie expression, or extend jquery object with cookie function

you can use this plugin https://code.google.com/p/cookies/wiki/Documentation#With_jQuery

TO use Cookies check the jQUery Cookie plugin

https://github.com/carhartl/jquery-cookie

You can then do:

$.cookie("test", 1);

To delete:

$.removeCookie("test");

Additionally, to set a timeout of a certain number of days (5 here) on the cookie:

$.cookie("test", 1, { expires : 5 });

If the expires option is omitted, then the cookie becomes a session cookie, and is deleted when the browser exits.

To cover all the options:

$.cookie("test", 1, {
   expires : 10,           //expires in 10 days

   path    : '/',          //The value of the path attribute of the cookie 
                       //(default: path of page that created the cookie).

   domain  : 'jquery.com',  //The value of the domain attribute of the cookie
                       //(default: domain of page that created the cookie).

   secure  : true          //If set to true the secure attribute of the cookie
                       //will be set and the cookie transmission will
                       //require a secure protocol (defaults to false).
});

To read back the value of the cookie:

var cookieValue = $.cookie("test");

You may wish to specify the path parameter if the cookie was created on a different path to the current one:

var cookieValue = $.cookie("test", { path: '/foo' });

Here is an example what you are trying to achieve. See if it works for you

<body>
        <script>
            $(document).ready(function(){
                $("#btn").click(function(){
                    var text1 = $('#text1').val();
                    var text2 = $('#text2').val();
                    $.cookie('text1', text1);
                    $.cookie('text2', text2);
                });
                checkCookieValues();
            });
            function checkCookieValues(){
                if ($.cookie('text1')!=="undefined") {
                    $('#text1').val($.cookie('text1'));
                }
                if ($.cookie('text2')!=="undefined") {
                    $('#text2').val($.cookie('text2'));
                }
            }
        </script>
        <form name="trial" id="trial">
            <input type="text" value="" id="text1" name="text1"/>
            <input type="text" value="" id="text2" name="text2"/>
            <input type="button" value="btn" id="btn"/>
        </form>
    </body>

NOTE: Jquery cookie plugin is required to use cookies through jquery
