C# 处理jquery变量，剪切部分，然后放入codebehind，如何处理？

c背后的代码#

是否可以从

？id=2

中提取“2”号，然后将其放入

cmd.Parameters.AddWithValue（“@category\u id”，p）中
您的浏览器可以通过表单提交或通过JavaScript发出POST请求向服务器发送数据

jQuery有一个post（）方法，对您来说可能是这样的：

                using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString()))
            {
                SqlCommand cmd = new SqlCommand();

                cmd.Connection = conn;
                cmd.CommandText = @"UPDATE [categories] SET [category_name] = @category_name WHERE [category_id] = @category_id";
                cmd.Parameters.AddWithValue("@category_name", val);
                cmd.Parameters.AddWithValue("@category_id", p);
                conn.Open();
                cmd.ExecuteNonQuery();
                conn.Close();
            }
            Response.Redirect("panel.aspx");
        }

从

$(document).ready(function () {
$(function () {

    var newHash = "",

        $el;


    $(".insertPost").delegate(".category", "click", function () {

        window.location.hash = $(this).attr("href");

        return false;
    });

    $(window).bind('hashchange', function () {

        newHash = window.location.hash.substring(1);



    });

    $(window).trigger('hashchange');
    $(".category").click(function () {
        var p = window.location.hash.replace('#', '');
        alert(p)
    });
});

                using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ToString()))
            {
                SqlCommand cmd = new SqlCommand();

                cmd.Connection = conn;
                cmd.CommandText = @"UPDATE [categories] SET [category_name] = @category_name WHERE [category_id] = @category_id";
                cmd.Parameters.AddWithValue("@category_name", val);
                cmd.Parameters.AddWithValue("@category_id", p);
                conn.Open();
                cmd.ExecuteNonQuery();
                conn.Close();
            }
            Response.Redirect("panel.aspx");
        }

$.post( "ajax/test.html", function( data ) {
  $( ".result" ).html( data );
});
