Json ajax 带参数传递

function BindJson() {
        $.ajax({
            type: "POST",
            url: "NewPage.aspx/SerializeJson",
            data: "{}",
            contentType: "application/json",
            dataType: "json",
            success: function (data1) {
                alert(data1);
            }
        })
    }
    [WebMethod]
        public static string SerializeJson()
        {
            JavaScriptSerializer js = new JavaScriptSerializer();
            //Person p2 = js.Deserialize<Person>(str);
            return "";
        }

如何将参数作为数据传递给我的 serializeJson 函数？

这对您有用（下面是完整的工作代码示例）。关键是传入一个Person对象。另外，我使用了一个简单的 Web 服务 (myService.asmx)，而不是 aspx 页面。如果不需要的话，为什么要费心去处理额外的开销呢？

关键是，在客户端创建一个 Person 对象，然后使用JSON.stringify http://msdn.microsoft.com/en-us/library/cc836459%28v=vs.85%29.aspx将 Person 对象传递给 Web 服务。

JavaScript

<script type="text/javascript">
    function BindJson() {
        $.ajax({
            type: "POST",
            url: "myService.asmx/SerializeJson",
            data: JSON.stringify({ person:{ firstName: "Denny", lastName: "Cherian", department: "Microsoft PSS", address: { addressline1: "Microsoft India GTSC", addressline2: "PSS - DSI", city: "Bangalore", state: "Karnataka", country: "India", pin: "560028" }, technologies: ["IIS", "ASP.NET", "JavaScript", "AJAX"] }}),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data1) {
                alert(data1.d);
            },
            error: function (request, status, errorThrown) {
                alert(status);
            }
        });
    }

    $(document).ready(function() {
        BindJson();    
    });
</script>
