javaScript高级程序设计之JSON

IE8以下请求助神之Douglas Crockford：https://github.com/douglascrockford/json-js

JSON是一种格式化的字符串，特别适合在网络上传输，由Douglas Crockford发明。

JSON语法可以表示三种类型的值：

简单值：字符串、数值、布尔值和null

对象

数组

特别说明：JSON属性名必须加双引号；而Javascript对象的属性如果是合法的标示符则不用加双引号。

// 一个javascript对象var conference = {      Conference: "Future Marketing",       Address: "Shanghai",      Members:[          {              name: "Bob",              age: 32,              company: "Oracle",              enginner: true          },          {              name: "John",              age: 30,              compancy: "Google",              enginner: false          }      ]};var jsontext = JSON.stringify(conference, ["Conference", "Address"]);// string: {"Conference":"Future Marketing","Address":"Shanghai"}var anotherObj = JSON.parse(jsontext, function (key, value) {    if (key === "Conference") {        return "a conference";    } else {        return value;    }});// object: { Conference="a conference", Address="Shanghai"}
