json解析,JSON(Javascr ipt Object Notation, JS 对象标记) 是一种轻量级的数据交换格式。它基于 ECMAscr ipt (w3c制定的js规范)的一个子集，采用完全独立于编程语言的文本格式来存储和表示数据。简洁和清晰的层次结构使得 JSON 成为理想的数据交换语言。 易于人阅读和编写，同时也易于机器解析和生成，并有效地提升网络传输效率。(JSON parsing, JSON (Javascr ipt, Object, Notation, JS object tags) is a lightweight data interchange format. It is based on a subset of ECMAscr ipt (the JS specification of W3C), which stores and represents data in a text format entirely independent of the programming language. The concise and clear hierarchy makes JSON an ideal data exchange language. Easy to read and write, but also easy to machine analysis and generation, and effectively improve the efficiency of network transmission.)
