无法将JSON字符串化数组传递给PageMethod [英] Trouble Passing JSON Stringified Array to PageMethod

问题描述

我无法将JSON字符串化数组传递给PageMethod

I am having trouble passing a JSON stringified array to a PageMethod

[{
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "8",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}, {
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "9",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}, {
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "5",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}, {
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "13",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}, {
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "6",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}, {
    "StartDate": "3/1/2011",
    "EndDate": "3/31/2011",
    "UserId": "11",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}]

当我收到这个ajax请求时，'jsonText'包含上面列出的数据

When I get to this ajax request, 'jsonText' contains the data listed above

    function GetUserSchedules() {           
        var jsonText = $.toJSON(arrParams);
        $.ajax({
            type: "POST",
            url: "/myurl/jquery.aspx/GenerateUserSchedules",
            data: "{" + jsonText + "}",
            contentType: "application/json",
            dataType: "json",
            success: AjaxSucceeded
            ,
            error: AjaxFailed
        });
    }

Pagemethod:

The Pagemethod:

    [System.Web.Script.Services.ScriptMethod]
    [System.Web.Services.WebMethod]
    public static void GenerateUserSchedules(Data[] data)
    {
    //do stuff; will return data but for now, just keeping it like this
            System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();       
}

数据类:

[Serializable]
public class Data
{
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
    public int UserID { get; set; }
    public string ViewSelectedValue { get; set; }
    public string ViewSelectedItem { get; set; }
    public string OrgSelectedValue { get; set; }
}

每次发送ajax请求时，都会执行错误函数.我在做什么错了?

Every time the ajax request is sent the error function executes. What am I doing wrong?

推荐答案

这是日期的常见问题. JavaScriptSerializer希望采用以下格式的日期才能成功解析它们:

That's a common issue with dates. The JavaScriptSerializer expects dates in the following format in order to parse them successfully:

{
    "StartDate": "\/Date(983401200000)\/",
    "EndDate": "\/Date(985989600000)\/",
    "UserId": "8",
    "DdlViewSelectedValue": "zzz#",
    "DdlViewSelectedItem": "zzz",
    "DdlOrgSelectedValue": "8"
}

其中983401200000表示自1970年1月1日以来的世界协调时间(UTC)的毫秒数.

where 983401200000 represents the number of milliseconds since January 1, 1970 in Universal Coordinated Time (UTC).

文档中的报价:

日期对象，在JSON中表示为 "\/日期(滴答数)\/".这 滴答数为正或 负的long值，指示 的刻度数(毫秒) 自午夜01起已经过去 1970年1月UTC.

Date object, represented in JSON as "\/Date(number of ticks)\/". The number of ticks is a positive or negative long value that indicates the number of ticks (milliseconds) that have elapsed since midnight 01 January, 1970 UTC.

支持的最大日期值为 MaxValue(12/31/9999 11:59:59 PM)和 支持的最小日期值为 最小值(1/1/0001 12:00:00 AM).

The maximum supported date value is MaxValue (12/31/9999 11:59:59 PM) and the minimum supported date value is MinValue (1/1/0001 12:00:00 AM).
