Silverlight的几个知识点(二)

 1,Silverlight 与JS交互：

<1>,silverlight 调用js：

HtmlPage.Window.Invoke("函数名",new object[] { 参数数组});

HtmlPage.Window.CreateInstance("函数名",new object[] { 参数数组});

<2>,JS 调用silverlight方法：

HtmlPage.RegisterScriptab<a href="http://code.js-code.com/tag/Leo/" target="_blank" class="keywords">Leo</a>b<a href="http://code.js-code.com/tag/je/" target="_blank" class="keywords">je</a>ct("RPFrame",this<a href="http://code.js-code.com/tag/" target="_blank" class="keywords">);</a>// 1，<a href="http://code.js-code.com/tag/zhuce/" target="_blank" class="keywords">注册</a> [ScriptableMember] // 2,<a href="http://code.js-code.com/tag/biaoji/" target="_blank" class="keywords">标记</a> public <a href="http://code.js-code.com/tag/dateti/" target="_blank" class="keywords">dateti</a>R_125_11845@e GetDataFrom() <a href="http://code.js-code.com/tag/" target="_blank" class="keywords">{</a> return Utility.StartTime; } function pluginLoaded(sender,args) <a href="http://code.js-code.com/tag/" target="_blank" class="keywords">{</a> // 3,JS<a href="http://code.js-code.com/tag/diaoyong/" target="_blank" class="keywords">调用</a> slPlugin = sender.getHost(<a href="http://code.js-code.com/tag/" target="_blank" class="keywords">);</a> __dtFrom = slPlugin.content.RPFrame.GetDataFrom(<a href="http://code.js-code.com/tag/" target="_blank" class="keywords">);</a> }

7，自定义的messageBox

详见：http://www.cnblogs.com/hedonister/archive/2009/08/02/1537142.html

8,定义Control的热区
