我想在ASP.NET C#应用程序中使用以下代码调用Web方法:
Jquery:
jQuery.ajax({
url: 'AddToCart.aspx/AddTo_Cart',
type: "POST",
data: "{'quantity' : " + total_qty + ",'itemId':" + itemId + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
beforeSend: function () {
alert("Start!!! ");
},
success: function (data) {
alert("a");
},
failure: function (msg) { alert("Sorry!!! "); }
});
C# 代码:
[System.Web.Services.WebMethod]
public static string AddTo_Cart(int quantity, int itemId)
{
SpiritsShared.ShoppingCart.AddItem(itemId, quantity);
return "Add";
}
但它总是调用 page_load。我该如何解决?
