Step1 : plugin

                    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-cookie/1.4.1/jquery.cookie.min.js" integrity="sha512-3j3VU6WC5rPQB4Ld1jnLV7Kd5xr+cq9avvhwqzbH/taCRNURoeEpoPBK9pDyeukwSxwRPJ8fDgvYXd6SkaZ2TA==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
                    

Step 2: set & get cookie

Set cookie

                    $.cookie("Name", "manoj");
                    

get cookie

                    $.cookie("Name");
                    

Step3 : store multiple values

                    var cartItem=[];
                    cartItem.push({"pooja_id":1, "price": 100});

                    $.cookie("cart_item",JSON.stringify(cartItem));

                    

Parse data from cookie

                    var cartItem=JSON.parse($.cookie("cart_item"));
