问题描述

How can I convert a JavaScript object to a JSON string in a JavaScript function? I need the JSON string to pass to a JSP page.

推荐答案

Crockford库中有两个示例方法(由@Anonymous提出):

There are two sample methods in Crockford's library (as raised by @Anonymous):

对象的JSON字符串

var obj = JSON.parse('{ "property":"value" }');
alert (obj.property);

// value

对象为JSON字符串:

Object to JSON string:

var str = JSON.stringify({ "property":"value" })
alert (str);

//{ "property":"value" }

在大多数主要框架中，也都内置有执行此操作的方法.

There are also built in methods to do this in most of the major frameworks.
