}</span>5.扩展说明，兼容IE处理
使用jsonObject传送数据的时候，会存在ie7、8不兼容的问题。不支持json的stringify 方法。网上有一些兼容处理，认为不错的有：IE下JSON 没有定义
方法1、设置兼容模式：
IE8和IE9中都能正常执行（大概是IE8和IE9都提供了原生的JSON解析和序列化）
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
方法2、引用json2.js文件到页面
http://www.json.org/
搜索 json2.js,下载压缩包
把json2.js引入到页面，就OK了。
官网地址：https://github.com/douglascrockford/JSON-js/
<script type="text/javascript" src="/Scripts/json2.js"></script>
方法3、推断当前浏览器是否支持JSON对象。假设不支持。则引入json2.js文件---没试成功
if(typeof JSON == 'undefined'){
$("head").append($("<script type='text/javascript' src='../Js/json2.js'></script>"));
}
官网地址一般都非常难找到下载的入口，目測了下好像仅仅有把下copy的可能。这里提供一个下载地址：
json2下载地址：http://download.csdn.net/detail/tianyazaiheruan/7421331
