Newtonsoft.Json 为asp.net 3.5开发的

使用的库是:Newtonsoft.Json 为asp.net 3.5开发的 Beta4版本,获取数据库数据用的是

Microsoft EnterpriseLibrary 4.1

其中扩展了这个库的功能,使之最适合把DataTable,DataSet,DataRow转为JSON模式

另外使用了Jquery的$.getJSON来解析后台传过来的JSON格式

另参考了:http://blog.csdn.net/dujingjing1230/archive/2009/08/28/4495008.aspx 裴旭更网友的文章

一个老外MVP此人专门写了一个JSON的等一系列的库,叫什么WestWind,呵呵

下面是扩展的Newtonsoft.Json几个类

igtbl_addNew("Grid", 0, false, true); 这个函数解释一下,根据API上面说的,第三个参数是加行的时候,滚动条是否跑到新加的到行

这里设成false了,所以加的时候不会跟着动,第四个参数就是是否把加的那行设为活动行(set the newly added row as the active row for the grid)
