JS中找不到函数的定义
下面是ComponentArt里一个JS的代码，可是一些对象，我没有找到它的定义
比如：
ComponentArt_DragBeginHandler，ComponentArt_DragMoveHandler
这是怎么回事？它们如何执行或返回呢？我对JS的了解不够深，是不是有别的特殊的定义方式？
我ComponentArt的整个项目里都找了，这2个对象没有别处出现过。。。

}; --------------------编程问答-------------------- 看看页面是不是还引用别的Js文件了，可能在别的Js文件里， --------------------编程问答--------------------
找了，确实没有的 --------------------编程问答-------------------- 项目里可能引用了.dll文件，如System.office系列。 --------------------编程问答--------------------
我是就是源文件里看的，不可能再有DLL的封装了
补充：.NET技术 , ASP.NET
