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“\\/”)。

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;
});

我遇到了一些JSON日期的问题，并决定通过在SQL中解决日期问题来摆脱这个问题。将日期格式更改为字符串格式

select flddate from tblName

select flddate, convert(varchar(12), flddate, 113) as fldDateStr from tblName

通过使用fldDateStr，问题消失了，我仍然可以使用日期字段进行排序或其他目的。

使用jQuery自动转换日期$.parseJSON

注意:这个答案提供了一个jQuery扩展，添加了自动ISO和.net日期格式支持。

因为你使用Asp.net MVC，我怀疑你在客户端使用jQuery。我建议你阅读这篇有代码如何使用$的博客文章。parseJSON自动转换日期。

代码支持Asp.net格式的日期，就像你提到的，以及ISO格式的日期。所有日期都将使用$. parsejson()自动格式化。

在页面中添加jquery UI插件。

function JsonDateFormate(dateFormate, jsonDateTime) {
    return $.datepicker.formatDate(dateFormate, eval('new ' + jsonDateTime.slice(1, -1)));
};

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;
}
