jQuery can decode JSON strings natively with <a href="http://api.jquery.com/jQuery.parseJSON/" rel="noreferrer"><code>jQuery.parseJSON()</code></a>. 

For encoding though, i only know of a plugin : <a href="http://code.google.com/p/jquery-json/" rel="noreferrer">jquery-json</a>

Just go to <a href="http://closure-compiler.appspot.com/" rel="noreferrer">http://closure-compiler.appspot.com/</a>

jQuery does not need this functionality internally and thus does not provide a convenience method to do so.

JSON.stringify() is the standard and recommended way of encoding an object to a JSON string representation of that object. It is a method of the native JSON object in many browsers, and it is recommended you use json2.js (https://github.com/douglascrockford/JSON-js) to provide a fallback.

blocks|key|1111737|text|在使用jQuery时，通常不需要JSON.stringify()函数。以使用ajax向服务器发送javascript数据的常见情况为例，jquery有内置的函数来处理此问题：(来自http://api.jquery.com/category/ajax/的示例)|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1111738|$.post("test.php",+{+name:+"John",+time:+"2pm"+}+);

++++alert("JSON+Data:+"+%2B+json.users[3].name);
});|code-block|syntax|javascript|1111739|在上面的所有示例中，发送的javascript数据都是由jQuery自动序列化的。|1111740|这些情况下的序列化不同于JSON.Stringify()，而是将数据序列化为html查询字符串(参见：http://en.wikipedia.org/wiki/Query_string#Structure)。|1111741|但是，这种形式的序列化适用于大多数(但不是所有)应用程序|1111742|entityMap|0|LINK|mutability|MUTABLE|url|http://api.jquery.com/category/ajax/|1|http://en.wikipedia.org/wiki/Query_string#Structure^0|2I|10|0|0|0|0|1F|1F|1|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|D|3|E|5|F|7|12|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|13|8|@]|9|@]|C|$]]|$1|K|3|L|5|6|7|14|8|@]|9|@$A|15|B|16|1|17]]|C|$]]|$1|M|3|N|5|6|7|18|8|@]|9|@]|C|$]]|$1|O|3|-4|5|6|7|19|8|@]|9|@]|C|$]]]|P|$Q|$5|R|S|T|C|$U|V]]|W|$5|R|S|T|C|$U|X]]]]

Often the JSON.stringify() function is not required when using jQuery. Take for example the common case of using ajax to send javascript data to the server, jquery has built-in functions to handle this: (examples from <a href="http://api.jquery.com/category/ajax/" rel="nofollow">http://api.jquery.com/category/ajax/</a>)

<pre><code>$.post("test.php", { name: "John", time: "2pm" } );
$.post("test.php", { 'choices[]': ["Jon", "Susan"] });
$.getJSON("test.js", { name: "John", time: "2pm" }, function(json) {
 alert("JSON Data: " + json.users[3].name);
});
</code></pre>

In all the examples above the javascript data sent is serialized by jQuery automatically.

The serialization in these cases is not the same as JSON.Stringify(), instead the data is serialised into a html query string (see: 
<a href="http://en.wikipedia.org/wiki/Query_string#Structure" rel="nofollow">http://en.wikipedia.org/wiki/Query_string#Structure</a>). 

However this form of serialization is fine for most (but not all) applications

Apparently jQuery has the ability to decode a given object or string into a JSON object. However, I have a JS object that I need to POST back to the server and I find no utility in jQuery that wraps the JSON.stringify() function. That function is found in Chrome, Safari 4, FF3.6, and IE8 but is not found in earlier browsers. I can use it natively in the browsers that support it, but otherwise am forced to fall back to using Crockford's JSON scripts.

Is there some built-in with jQuery that handles JSON encoding and decoding that takes the place of the Crockford scripts?

显然，jQuery能够将给定的对象或字符串解码为JSON对象。但是，我有一个需要回发到服务器的JS对象，并且我在jQuery中找不到包装JSON.stringify()函数的实用程序。该函数在Chrome、Safari4、FF3.6和IE8中都有，但在更早的浏览器中没有。我可以在支持它的浏览器中原生使用它，但除此之外，...
