Question

这里是AJAX的新手。一直试图使用AJAX发送到我的数据库，但是无法正常工作。在我的aspx.cs中：

[WebMethod]
    public static void saveMsg(string roomCode, string userName, string msg)
    {
        using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["LBConnectionString"].ConnectionString))
        {
            SqlCommand cmd = con.CreateCommand();

            cmd.CommandText = "INSERT into chatTable(roomCode, uName, msg) VALUES (" + roomCode + ", '" + userName + "', + '" + msg + "')";
            cmd.Connection = con;
            con.Open();

            cmd.ExecuteNonQuery();

            con.Close();
        }
    }

我正在尝试使用AJAX和C＃ASP.NET插入数据。这是我的aspx文件

$.ajax({
                    type:'POST',
                    contectType: "application/json; charset=utf-8",
                    dataType: "json",
                    url:"Room.aspx?Board='" + roomCode + "'",
                    data: "{'roomCode':'" + roomCode + "','uName':'" + userName + "','msg':'" + <%=message.ClientID %> + "'}",
                })

完整网址为http://localhost:1759/Room?Board='// roomcode'。

有什么问题吗？就像我把url放入AJAX函数一样？提前谢谢！

编辑：是否需要将数据类型设置为JSON？也是JSON的新手......

Answer 1

试试这段代码：

Javascript：

function Getpath() {
if (!window.location.origin) {
    window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port : '');
}
var Domainpath = window.location.origin + "/";
if (Domainpath.indexOf("localhost") == -1) {
    return Domainpath;
}
else {
    return Domainpath;
}
}

<强>的Ajax：

您将获得Getpath() Method中的路径。

var path = Getpath();
$.ajax({
                type:'POST',
                contectType: "application/json; charset=utf-8",
                dataType: "json",
                url: path +"Room.aspx?Board='" + roomCode + "'",
                data: "{'roomCode':'" + roomCode + "','uName':'" + userName + "','msg':'" + <%=message.ClientID %> + "'}",
            })

Answer 2

您需要将正确的网址传递给致电方法。

$.ajax({
       type:'POST',
       contectType: "application/json; charset=utf-8",
       dataType: "json",
       url:"Room.aspx/saveMsg",
       data: "{'roomCode':'" + roomCode + "','uName':'" + userName + "','msg':'" + <%=message.ClientID %> + "'}",
   })

使用ASP.NET，c＃和jQuery发送到数据库
