服务器|源代码   下面的这个例子实现了在服务器端得到可编辑Iframe的HTML源代码非典功能。代码很简单，这里疾苦不多解释了。代码如下：
  
  GetIframeHtml.axpx
  
  <% Page Language="<a
   ifrHTML.document.designMode = "on";
   </script>
   </body>
  </HTML>
  
  
  GetIframeHtml.aspx.vb
  
  Public Class GetIframeHtml
   Inherits System.Web.UI.Page
   Protected WithEvents cmdSend As System.Web.UI.WebControls.Button
   Protected WithEvents ifrHTML As System.Web.UI.HtmlControls.HtmlGenericControl
  
  #Region " Web Form Designer Generated Code "
  
   'This call is required by the Web Form Designer.
   <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
  
   End Sub
  
   Private Sub Page_Init(ByVal sender As System.Object,_
   ByVal e As System.EventArgs) Handles MyBase.Init
   'CODEGEN: This method call is required by the Web Form Designer
   'Do not modify it using the code editor.
   InitializeComponent()
   End Sub
  
  #End Region
  
   Private Sub Page_Load(ByVal sender As System.Object,_
   ByVal e As System.EventArgs) Handles MyBase.Load
   cmdSend.Attributes.Add("onClick", "document.frmMain.hidValue.value" + _
   " = ifrHTML.document.body.innerHTML;")
   End Sub
  
  
   Private Sub cmdSubmit_Click(ByVal sender As System.Object,_
   ByVal e As System.EventArgs) Handles cmdSend.Click
   Dim strValue As String
   strValue = Request.Form("hidValue")
   Response.Write(Server.HtmlDecode(strValue))
   End Sub
  
  End Class
