如何在Asp.Net服务器端使用JavaScript对象

本文关键字：JavaScript 对象 服务器端 Net Asp | 更新日期: 2023-09-27 18:13:53

嗨，我必须通过在asp.net中从客户端到服务器端调用方法在服务器端传递javascript对象。

我这样做。我在方法中传递javascript对象。现在我想在服务器端代码中使用这个对象，但是我不能这样做。

我一直这样做到现在，如果我做错了什么，请告诉我。

aspx code: 

 <html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
 <script src="Scripts/jquery.min.js" type="text/javascript"></script>
    <script type="text/javascript">
//        var JsonNewOne = {
//            returnHeader: { "ID": -1, "OrderHeaderID": 5, "StatusID": 1, "DeliveryCharge": 0, "CreatedBy": "77777777", "ApprovedBy": "77777777" }
        //        };
        var JsonNewOne = { "forename": "Phil", "surname": "Curnow", "age": 41 };
        var jsonobj = eval(JsonNewOne);
        var abc = JSON.stringify(jsonobj);
        function GetServerDate(format) {
            $.ajax({
                type: "post",
                url: "JSONTest.aspx/GetServerDate",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: '{"format":"' + format + '"}',
                success: function (result) {
                    OnSuccess(result.d);
                },
                error: function (xhr, status, error) {
                    OnFailure(error);
                }
            });
        }
        function OnSuccess(dateTime) {
            if (dateTime) {
                document.getElementById("currentDate").innerHTML = dateTime;
            }
        }
        function OnFailure(error) {
            alert(error);
        }
    </script> 
</head>
<body style = "font-family:Arial; font-size:10pt">
<form id="form1" runat="server">
<div>
    <input type="button" value="Show UTC Server Time" onclick="GetServerDate(JsonNewOne)" />
    <input type="button" value="Show Local Server Time" onclick="GetServerDate(JsonNewOne)" />
    <label id="currentDate">
        This is current Date Time in Web Server</label>
</div>
</form>
</body>
</html>

服务器端代码:

 [System.Web.Services.WebMethod]
    public static string GetServerDate( string format)
    {
        try
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Person));
            MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(format));
            Person obj = (Person)ser.ReadObject(stream);

        }
        catch (Exception ex)
        {
            return null;
        }
    }

Person.cs文件:

public class Person
{
    public string forename { get; set; }
    public string surname { get; set; }
    public int age { get; set; }
}

如何在Asp.Net服务器端使用JavaScript对象

    var JsonNewOne = { "forename": "Phil", "surname": "Curnow", "age": 41 };
    var jsonobj = eval(JsonNewOne);
    var abc = JSON.stringify(jsonobj);
    function GetServerDate(abc) {
        $.ajax({
            type: "post",
            url: "JSONTest.aspx/GetServerDate",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            data: '{"format":"' + abc + '"}',
            success: function (result) {
                OnSuccess(result.d);
            },
            error: function (xhr, status, error) {
                OnFailure(error);
            }
        });
    }
    function OnSuccess(dateTime) {
        if (dateTime) {
            document.getElementById("currentDate").innerHTML = dateTime;
        }
    }
    function OnFailure(error) {
        alert(error);
    }
</script>
