请帮我找出原因并重新编写代码提前谢谢。

因为这是POST，您需要return false for your form submit（例如，btnsubmit的客户端处理程序）。此外，由于TextBox1和TextBox2的类型为<asp:TextBox>，因此您需要捕获其ClientID以在客户端脚本中正确引用它们。下面的代码应该有效。

function AjaxSucceeded(result) {
    alert(result.d);
    var Emp = result.d;
    $("#output").append('<p>' + Emp.Sname + ' ' + Emp.Sno + '</p>');
}

function AjaxFailed(result) {
    alert(result.status + ' ' + result.statusText);
    alert("Failure");
}

$(document).ready(function() {
    $("#btnsubmit").click(function(e) {
        $.ajax({
            "type": "POST",
            "url": "loginform.aspx/getdataval",
            "data": "{'uname':'" + $("#<%=TextBox1.ClientID %>").val() + "','passwod':'" + $("#<%=TextBox2.ClientID %>").val() + "'}",
            "contentType": "application/json;charset=utf-8",
            "dataType": "json",
            "success": function(msg) {
                alert("welcome");
                AjaxSucceeded(msg);
            },
            "error": AjaxFailed
        });
        //required because "type" is "POST"
        e.preventDefault();
        return false;
        //although it's a good idea anyway because we
        //don't want a postback.
    });
});
