I am getting the following error with my jquery ajax call in IE9, where I am using Json.stringify().

微软JScript运行时错误：JSON未定义

Microsoft JScript runtime error: 'JSON' is undefined

同样的功能是为我工作，直到昨天仍然工作在我的同事的机器和铬我的机器上。但没有明显的原因已经停止工作今天我的机器上。

The same function was working for me till yesterday and still works on my colleagues machine and on chrome on my machine. But for no apparent reason has stopped working on my machine today.

May you please help me understand, what is causing it?

谢谢！
