使用Javascript调用Silverlight

我试图通过javascript调用silverlight应用程序的公共方法，该方法只设置一个私有变量。当我试图设置文件名时，我得到一个javascript错误。fu.Content.myObject未定义。有人能发现错误吗

---

如果在Javascript

SetFileName

函数中不大写

Content

，它是否有效

fu.content.myObject.SetFileName("10");

这是我看到的我的程序和你的代码调用Silverlight对象的唯一明显区别。

不，同样的问题，尽管IE给出了“未指定的错误”，firefox是一个未定义的对象。
