如何解析JSON以接收JavaScript中的Date对象？ [英] How to parse JSON to receive a Date object in JavaScript?

问题描述

我有以下JSON：

  \ / Date（1293034567877）\ / 
  

这是.NET代码的结果：

  var obj = DateTime.Now; 
 var serializer = new System.Web.Script.Serialization.JavaScriptSerializer（）; 
 serializer.Serialize（obj）.Dump（）; 
  

现在我面临的问题是如何从JavaScript中创建一个Date对象。
所有我可以找到的是令人难以置信的正则表达式解决方案（许多包含错误）。

很难相信没有优雅的解决方案，因为这是所有的JavaScrip，我的意思是JavaScript代码试图读取JSON（JavaScript对象符号），这应该是一个JavaScript代码，在这一刻，事实证明这不是因为JavaScript在这里做得不好。

$ b $我也看到一些我不能做的eval解决方案（除了被指出是安全威胁）。

真的没办法做一个优雅的方式？

解决方案

没有日期的标准JSON表示形式。你应该做@jAndy建议，而不是序列化一个 DateTime 只需发送RFC 1123日期字符串 ToString（r）或从Unix-epoch编号的秒数，或者您可以在JavaScript中使用的其他内容来构建日期。

I have a following piece of JSON:

\/Date(1293034567877)\/

which is a result of this .NET code:

var obj = DateTime.Now;
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
serializer.Serialize(obj).Dump();

Now the problem I am facing is how to create a Date object from this in JavaScript. All I could find was incredible regex solution (many containing bugs).

It is hard to believe there is no elegant solution as this is all in JavaScrip, I mean JavaScript code trying to read JSON (JavaScript Object Notation) which is supposed to be a JavaScript code and at this moment it turns out it's not cause JavaScript cannot do a good job here.

I've also seen some eval solutions which I could not make to work (besides being pointed out as security threat).

Is there really no way to do it in an elegant way?

There is no standard JSON representation of dates. You should do what @jAndy suggested and not serialize a DateTime at all; just send an RFC 1123 date string ToString("r") or a seconds-from-Unix-epoch number, or something else that you can use in the JavaScript to construct a Date.
