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"}
