在IE下使用EasyUI form插件创建或编辑数据时(操作成功后会返回一段json)，始终无法运行回调函数，而是提示下载内容。
在IE9下的提示如下图：为了解决这个问题，需要将json字符串用下面的格式返回给客户端才行。
<body>
<pre>{"message":"保存成功","data":null,"success":true}</pre>
</body>
所以写了一个hack方法:
View Code 
1 /// <summary>
2 /// 前台Ajax请求的统一返回结果类
3 /// </summary>
4 public class AjaxResult
5 {
6 private AjaxResult()
7 {
8 }

10 private bool _isError = false;
11
12 /// <summary>
13 /// 是否产生错误
14 /// </summary>
15 public bool IsError { get { return _isError; } }

17 /// <summary>
18 /// 错误信息，或者成功信息
