Why not use the <a href="http://docs.jquery.com/UI/Datepicker/formatDate" rel="nofollow noreferrer">formatDate</a> function in the Datepicker jQuery-UI plugin for jQuery to generate the format your server-side requires?

blocks|key|1335964|text|您还可以对json2.js进行一些调整，使其始终使用自己的Date.prototype.toJSON，而不是可能的本机a。这里我取消了两行的注释，它可以正常工作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1335965|//+if+(typeof+Date.prototype.toJSON+!==+'function')+{

You could also adjust json2.js a bit to always use its own <code>Date.prototype.toJSON</code> instead of a possible native one. Here I uncommented two lines and it works correctly:

<pre><code>// if (typeof Date.prototype.toJSON !== 'function') {

 Date.prototype.toJSON = function (key) {

 return isFinite(this.valueOf()) ?
 this.getUTCFullYear() + '-' +
 f(this.getUTCMonth() + 1) + '-' +
 f(this.getUTCDate()) + 'T' +
 f(this.getUTCHours()) + ':' +
 f(this.getUTCMinutes()) + ':' +
 f(this.getUTCSeconds()) + 'Z' : null;
 };

 String.prototype.toJSON =
 Number.prototype.toJSON =
 Boolean.prototype.toJSON = function (key) {
 return this.valueOf();
 };
// }
</code></pre>

blocks|key|1336047|text|我添加了下面的javascript就可以工作了：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1336048|//+Added+to+make+dates+format+to+ISO8601

I got this working adding the following javascript:

<pre><code>// Added to make dates format to ISO8601
Date.prototype.toJSON = function (key) {
 function f(n) {
 // Format integers to have at least two digits.
 return n &lt; 10 ? '0' + n : n;
 }

 return this.getUTCFullYear() + '-' +
 f(this.getUTCMonth() + 1) + '-' +
 f(this.getUTCDate()) + 'T' +
 f(this.getUTCHours()) + ':' +
 f(this.getUTCMinutes()) + ':' +
 f(this.getUTCSeconds()) + '.' +
 f(this.getUTCMilliseconds()) + 'Z';
};
</code></pre>

I'm sure this probably slows down the serialization, but it seems to make things consistent across browsers.

You might want to consider beefing up the server, 
to recognize any valid ISO 8601 time format:

'2010-02-08T03:37:34.327Z'

'2010-02-08T03:38:06Z'

'2010-02-08T03:38+01:00'

'2010-02-08T03:34:18-05:00'

'2010-02-08T03:34Z'

'2010-02-08'

This is a method to convert any iso string to a javascript date object.
It could be used on the server with a little translation:

<pre><code>Date.from_iso= function(s){
 var D, M= [], hm, min= 0, d2,
 Rx= /([\d:]+)(\.\d+)?(Z|(([+\-])(\d\d):(\d\d))?)?$/;
 D= s.substring(0, 10).split('-');
 if(s.length&gt; 11){
 M= s.substring(11).match(Rx) || [];
 if(M[1]) D= D.concat(M[1].split(':'));
 if(M[2]) D.push(Math.round(M[2]*1000));// msec
 }
 for(var i= 0, L= D.length; i&lt;L; i++){
 D[i]= parseInt(D[i], 10);
 }
 D[1]-= 1;
 while(D.length&lt; 6) D.push(0);
 if(M[4]){
 min= parseInt(M[6])*60+ parseInt(M[7], 10);// timezone not UTC
 if(M[5]== '+') min*= -1;
 }
 try{
 d2= Date.fromUTCArray(D);
 if(min) d2.setUTCMinutes(d2.getUTCMinutes()+ min);
 }
 catch(er){
 // bad input
 }
 return d2;
}
Date.fromUTCArray= function(A){
 var D= new Date;
 while(A.length &lt; 7) A.push(0);
 var T= A.splice(3, A.length);
 D.setUTCFullYear.apply(D, A);
 D.setUTCHours.apply(D, T);
 return D;
}
</code></pre>

I have this code in an HTML page:

<pre><code>alert(JSON.stringify(new Date()));
</code></pre>

I'm including the latest <a href="https://github.com/douglascrockford/JSON-js/blob/master/json2.js" rel="noreferrer">json2.js</a> (2009-09-29 version) in my page to support older browsers without JSON.stringify(). I also have jquery-1.3.2.js included. I believe in newer browsers with native JSON support, it just passes through to the native JSON feature.

Here's the results I get in different browsers:

<pre><code>IE 8 on Windows XP: "2010-02-07T21:39:32Z"
Chrome 4.0 on Windows XP: "2010-02-07T21:39:59Z"
Firefox 3.0 of Windows XP: "2010-02-07T21:40:41Z"
Chrome 4.0 on Ubuntu linux: "2010-02-07T21:41:49Z"
Firefox 3.0 on Ubuntu linux: "2010-02-07T21:42:44Z"
Chrome 4.0 on Mac OSX: "2010-02-07T21:43:56Z"
Safari on Mac OSX: "2010-02-07T21:45:21Z"
Firefox 3.5 on Mac OSX: "2010-02-07T21:44:10.101Z"
</code></pre>

Notice the last one? It contains milliseconds, and none of the others do. I don't have FF3.5 installed on any other systems, but I'm assuming they would have the same results.

Is there something I can do to make all dates on all platforms stringify the same? My backend REST service can be configured with a format string to deserialize JSON dates, but it can't support multiple formats, just one.

我在一个HTML页面中有以下代码：alert(JSON.stringify(new Date()));我在我的页面中包含了最新的 (2009-09-29版本)，以支持没有JSON.stringify()的旧浏览器。我还包含了jquery-1.3.2.js。我相信具有原生JSON支持的较新浏览器，它只是传递到原生JSON...
