我正在使用 asp .net。我想知道如何修改它,以便每次添加商品时都可以通知服务器,并且能够在将商品放入购物车后运行一些 aspx 代码。
我需要做什么才能拥有类似的东西:
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Item_Dropped(String itemName)
{
}
}
基本上这样我就可以在服务器上做一些事情,比如将此项目添加到数据库中,而无需刷新页面。
有没有关于如何在 asp .net 中做这种事情的例子?
谢谢
