稳扎稳打Silverlight(27) - 2.0网页之可脚本化, 与DOM的交互, 与JavaScript的交互
作者：webabcd
介绍
Silverlight 2.0 使用c#开发可脚本化的代码，Silverlight与宿主页面的DOM之间的交互，Silverlight与宿主页面的JavaScript之间的交互
ScriptableMemberAttribute - 需要脚本化的属性、方法、事件要标记为此
HtmlPage.RegisterScriptableObject - 将可脚本化对象注册到客户端
HtmlElement - 表示网页的文档对象模型 (DOM) 中的 HTML 元素
HtmlWindow - 提供 JavaScript 的 window 对象的 Silverlight 端的托管表示形式
