在Flex中使用Json （转载收藏）
<span style="font-family: georgia, verdana, Arial, helvetica, sans-seriff; font-size: 13px; color: #4b4b4b; line-height: 20px;">要用到JSON,看了一篇（http://bbs.actionscript3.cn/thread-1657-1-1.html ）的扫盲贴，在Flex中使用Json十分方便。json是介于纯文本方式与xml方式之间的一种格式，json能做到的事情，xml完成可以做到。为什么要用json呢，我看大部分还是像我一样，不得不用。json是ajax数据传输的首选，现有的项目使用的已经是json，如果增加flex界面时也使用json,那改动就会非常少。扫盲贴中说出的三个理由，我觉得这一个最充分。要在flex中使用json，首先要下一个json包。是官方的，却在官方怎么也载不下来。终于在CSDN上用了３分才down下来。放在附件中，需要的可以拿去用。
贴一个例子：
<div style="background-color: #eeeeee; font-family: 'Courier New'; font-size: 13px; padding-right: 5px; padding-bottom: 4px; padding-left: 4px; padding-top: 4px; border: 1px solid #cccccc;" class="cnblogs_code">http://www.cnblogs.com/Images/OutliningIndicators/None.gif<?xml version="1.0" encoding="utf-8"?>
