无法获取我的ajax“添加到购物车局部”功能以在ASP.NET MVC中工作

Question

I'm looking to call an ajax function to add to my cart partial I have made however it doesn't seem to be working. I think the product Id isn't being linked to it for some reason. Here is the code:

 <div class="addtocart">
            <a href="#" class="addtocart">Add to cart</a>

            <span class="ajaxmsg">The product has been added to your cart. </span>
  </div>
<script>
$(function () {


/*
* Add to cart
*/

$("a.addtocart").click(function (e) {
    e.preventDefault();

    $("span.loader").addClass("ib");

    var url = "/cart/AddToCartPartial";

    $.get(url, { id: @Model.Id }, function (data) {
        $(".ajaxcart").html(data);
    }).done(function () {
        $("span.loader").removeClass("ib");
        $("span.ajaxmsg").addClass("ib");
        setTimeout(function () {
            $("span.ajaxmsg").fadeOut("fast");
            $("span.ajaxmsg").removeClass("ib");
        }, 1000);
    });
});


  </script>

I have found a solution but When I use this link it works but it takes to an addtocartpartial which I don't want.

@Html.ActionLink("Test", "AddtoCartPartial", "Cart", new { id = Model.Id }, new { @class = "addtocart" })

Is there another way of calling the ajax script or a way of avoiding the link to taking me to the addtocartpartial page on select?

My controller for addtocartpartial is:

   public ActionResult AddToCartPartial(int id)
    {
        // Init CartVM list
        List<CartVM> cart = Session["cart"] as List<CartVM> ?? new List<CartVM>();

        // Init CartVM
        CartVM model = new CartVM();

        using (Db db = new Db())
        {
            // Get the product
            ProductDTO product = db.Products.Find(id);

            // Check if the product is already in cart
            var productInCart = cart.FirstOrDefault(x => x.ProductId == id);

            // If not, add new
            if (productInCart == null)
            {
                cart.Add(new CartVM()
                {
                    ProductId = product.Id,
                    ProductName = product.Name,
                    Quantity = 1,
                    Price = product.Price,
                    Image = product.ImageName
                });
            }
            else
            {
                // If it is, increment
                productInCart.Quantity++;
            }
        }

        // Get total qty and price and add to model

        int qty = 0;
        decimal price = 0m;

        foreach (var item in cart)
        {
            qty += item.Quantity;
            price += item.Quantity * item.Price;
        }

        model.Quantity = qty;
        model.Price = price;

        // Save cart back to session
        Session["cart"] = cart;

        // Return partial view with model
        return PartialView(model);
    }

You may have a default route set for id parameters. In that case you could append the value to the url in the format controller/action/{id} , and remove the parameters from the $.get . The code below may work for you:

var url = "/cart/AddToCartPartial/" + "@Model.Id";

$.get(url, function (data) {
    $(".ajaxcart").html(data);
}).done(function () {
    // ... other code
});

Or you could try appending the id using query parameter style:

var url = "/cart/AddToCartPartial?id=" + "@Model.Id";
