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

GetIframeHtml.aspx.vbPublic 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.

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
