仅用aspx文件实现Ajax调用后台cs无刷新程序。（实例）

两个文件：aaa.aspx 和aaa.aspx.cs

一、aaa.aspx

<script type="text/javascript">
     
        function Request() {
            alert("1");
            $.ajax({
                type: 'post',url: 'Test442.aspx?method=Send2',// 【调用后台的事件】
                cache: false,success: function (data) {
                    if (data == '00000') {
                        //receive();
                    }
                    var tbReceive = $('#tbReceive').val();
                    $('#tbReceive').val(tbReceive + data + ";");
                },error: function (XMLHttpRequest,textStatus) {
                }
            });
        };
    </script>

protected void Page_Load(object sender,EventArgs e)
    {
        string result = "";
        if (!IsPostBack)
        {

            if (Request["method"] != null)
            {
                try
                {
                    switch (Request.QueryString["method"])
                    {
                        case "Send2":   
                           
                            result = Send2();   <span style="font-family: Arial,Helvetica,sans-serif;">// 【执行的事件send2】</span>

                            break;
                    }
                }
                catch (Exception ex)
                {
                    result = ex.Message;
                    LogManager.WriteLog(ex.Message);
                }
                Response.Clear();
                Response.ContentType = "text/plain";
                Response.ContentEncoding = System.Text.Encoding.UTF8;
                Response.Write(result);
                Response.End();
            }

        }
    }
