让我们扩展一下casperOne的答案。

JSON规范没有说明Date值。MS不得不进行调用，他们选择的路径是利用javascript字符串表示中的一个小技巧:字符串字面量“/”与“\/”相同，字符串字面量永远不会被序列化为“\/”(甚至“\/”也必须映射为“\\/”)。

参见http://msdn.microsoft.com/en-us/library/bb299886.aspx#intro_to_json_topic2获得更好的解释(向下滚动到“从JavaScript文字到JSON”)

One of the sore points of JSON is the lack of a date/time literal. Many people are surprised and disappointed to learn this when they first encounter JSON. The simple explanation (consoling or not) for the absence of a date/time literal is that JavaScript never had one either: The support for date and time values in JavaScript is entirely provided through the Date object. Most applications using JSON as a data format, therefore, generally tend to use either a string or a number to express date and time values. If a string is used, you can generally expect it to be in the ISO 8601 format. If a number is used, instead, then the value is usually taken to mean the number of milliseconds in Universal Coordinated Time (UTC) since epoch, where epoch is defined as midnight January 1, 1970 (UTC). Again, this is a mere convention and not part of the JSON standard. If you are exchanging data with another application, you will need to check its documentation to see how it encodes date and time values within a JSON literal. For example, Microsoft's ASP.NET AJAX uses neither of the described conventions. Rather, it encodes .NET DateTime values as a JSON string, where the content of the string is /Date(ticks)/ and where ticks represents milliseconds since epoch (UTC). So November 29, 1989, 4:55:30 AM, in UTC is encoded as "\/Date(628318530718)\/".

一个解决办法就是把它解析出来:

value = new Date(parseInt(value.replace("/Date(", "").replace(")/",""), 10));

然而，我听说在某个地方有一个设置，可以让序列化器用新的Date(xxx)语法输出DateTime对象。我试着把它挖出来。

JSON.parse()的第二个参数接受一个恢复函数，其中规定了在返回值之前最初是如何生成值的。

下面是一个关于date的例子:

var parsed = JSON.parse(data, function(key, value) {
  if (typeof value === 'string') {
    var d = /\/Date\((\d*)\)\//.exec(value);
    return (d) ? new Date(+d[1]) : value;
  }
  return value;
});

查看JSON.parse()的文档

js是一个扩展的datetime库，它也支持这个功能。http://momentjs.com/docs/#/parsing/asp-net-json-dates/

ex - Date(1198908717056-0700):时刻(“”)

这可能会有帮助。恰好输出

这里是我写的一些JavaScript代码，它设置了一个<input type="date">值，从一个从ASP传递的日期。净MVC。

var setDate = function(id, d) {
  if (d !== undefined && d !== null) {
    var date = new Date(parseInt(d.replace("/Date(", "").replace(")/", ""), 10));
    var day = ('0' + date.getDate()).slice(-2);
    var month = ('0' + (date.getMonth() + 1)).slice(-2);
    var parsedDate = date.getFullYear() + "-" + (month) + "-" + (day);
    $(id).val(parsedDate);
  }
};

你可以这样调用这个函数:

setDate('#productCommissionStartDate', data.commissionStartDate);

其中commissionStartDate是MVC传递的JSON日期。

我发现这是更改服务器端的最简单的方法。

using System.Collections.Generic;
using System.Web.Mvc;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
using Newtonsoft.Json.Serialization;

namespace Website
{
    /// <summary>
    /// This is like MVC5's JsonResult but it uses CamelCase and date formatting.
    /// </summary>
    public class MyJsonResult : ContentResult
    {
        private static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
            Converters = new List<JsonConverter> { new StringEnumConverter() }
        };

        public FindersJsonResult(object obj)
        {
            this.Content = JsonConvert.SerializeObject(obj, Settings);
            this.ContentType = "application/json";
        }
    }
}

对我来说有用的是创建一个包含date属性为字符串的视图模型。从域模型分配DateTime属性，并在为视图模型分配值时调用date属性上的. tostring()。

来自MVC操作方法的JSON结果将以与视图兼容的格式返回日期。

视图模型

public class TransactionsViewModel
{
    public string DateInitiated { get; set; }
    public string DateCompleted { get; set; }
}

域模型

public class Transaction{
   public DateTime? DateInitiated {get; set;}
   public DateTime? DateCompleted {get; set;}
}

控制器动作方法

public JsonResult GetTransactions(){

var transactions = _transactionsRepository.All;
        var model = new List<TransactionsViewModel>();

        foreach (var transaction in transactions)
        {
            var item = new TransactionsViewModel
            {
                ...............
                DateInitiated = transaction.DateInitiated.ToString(),
                DateCompleted = transaction.DateCompleted.ToString(),
            };

            model.Add(item);
        }
        return Json(model, JsonRequestBehavior.AllowGet);
}

这不是最优雅的方式，但对我来说很管用:

var ms = date.substring(6, date.length - 2);
var newDate = formatDate(ms);


function formatDate(ms) {

    var date = new Date(parseInt(ms));
    var hour = date.getHours();
    var mins = date.getMinutes() + '';
    var time = "AM";

    // find time 
    if (hour >= 12) {
        time = "PM";
    }
    // fix hours format
    if (hour > 12) {
        hour -= 12;
    }
    else if (hour == 0) {
        hour = 12;
    }
    // fix minutes format
    if (mins.length == 1) {
        mins = "0" + mins;
    }
    // return formatted date time string
    return date.getMonth() + 1 + "/" + date.getDate() + "/" + date.getFullYear() + " " + hour + ":" + mins + " " + time;
}
