Ajax无刷新删除GridView行（常用）

public static int Delete(int id)
       {
           var sql = " delete from Product where id="+id;
           return SqlHelper.NoQuery(sql);
       }

我以<a>标签为例：
<a href="#" class="shan" data-id=‘<%#Eval("id") %>‘>删除</a>

我们以Post为例：
 public class Delete : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            var id = Convert.ToInt32(context.Request.Form["data"]);
            int num = ProductManage.Delete(id);
            
            context.Response.ContentType = "application/json";
            context.Response.Write(num);
        }


        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }

我们已一个简单的例子去写：
<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(function() {
            $(".shan").live("click",
                function() {
                    if (!confirm("确定要删除吗？")) {
                        return;
                    }
                    var $old = $(this);
                    var id = $old.attr("data-id");
                    $.post("/Delete.ashx",
                        { id: id },
                        function(data) {
                            if (data>0) {
                                alert("删除成功！");
                                $old.closest("tr").remove();
                            }
                        });
                });
        })
    </script>
