我需要使用 ajax 将变量添加到会话状态中，当我尝试这个时它不起作用。任何人都可以帮我解决这个问题。当我单击按钮时它重定向到 Travellerinfo.aspx 页面

下面是我的 test.aspx

   <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="hotelbeds.test" %>

一定是

[WebMethod (EnableSession=true)]
        public static void addSession(String hotelcode)
        {
            HttpContext.Current.Session.Add("hotelcode", hotelcode);

        }

请注意：该方法必须是公共的、静态的，并且EnableSession属性必须为真。

编辑1：

添加'return false'以防止按钮的默认功能。按钮的默认功能是将表单发布到服务器。或者，event.preventDefault()可用于阻止默认功能。

<script type="text/javascript">
    function testbook(hotelcode) {

        $.ajax({
            type: "POST",
            url: "test.aspx/addSession",
            data: "{'hotelcode':'" + hotelcode + "'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                window.location.href = "Hotelresul.aspx";
            },
            error: function (err) {
                window.location.href = "TravellerInfo.aspx";
            }
        });


 return false;

    }

</script>

编辑2：

 protected void Page_Load(object sender, EventArgs ea)
        {
            ImageButton testbtn = new ImageButton();
            testbtn.OnClientClick = "return testbook('15000')";
            form1.Controls.Add(testbtn);

        }
