Solution 1:

Following is the description of Usage of jQuery cookie

Create session cookie:

$.cookie('the_cookie', 'the_value');

Create expiring cookie, 7 days from then:

$.cookie('the_cookie', 'the_value', { expires: 7 });

Create expiring cookie, valid across entire site:

$.cookie('the_cookie', 'the_value', { expires: 7, path: '/' });

Read cookie:

$.cookie('the_cookie'); // => "the_value"
$.cookie('the_cookie', { raw: true }); // => "the_value" not URL decoded
$.cookie('not_existing'); // => null

Delete cookie:

// returns false => No cookie found
// returns true  => A cookie was found
$.removeCookie('the_cookie'[, options]);

Note: when deleting a cookie, you must pass the exact same path, domain and secure options that were used to set the cookie, unless you're relying on the default options that is.
