主要的原理就是替换模板里的特殊字符。
1、静态模板页面 template.html,主要是定义了一些特殊字符,用来被替换。
- <!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
- <html>
- <head>
- <metahttp-equiv="Content-Type"content="text/html;charset=gb2312">
- <title>Title</title>
- </head>
- <body>
- <divstyle="width:417px;height:54px"align="center">
- <br/>
- Title</div>
- <divstyle="width:417px;height:8px">
- 浏览<fontcolor="red"><scriptsrc="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"></script></font>次Time</div>
- <divstyle="width:417px;height:100px">
- Content</div>
- <divstyle="width:416px;height:9px">
- Pager</div>
- <divstyle="width:416px;height:8px">
- <formid="form1"action="../AddComment.aspx"style="margin:0px">
- <inputid="Text1"type="text"/><Imgid="Image1"src="http://www.dwww.cn/UserInfo/CheckCode.aspx"/><br/>
- <textareaid="CommentContent"cols="20"rows="2"></textarea>
- <br/>
- <inputid="NewsId"type="hidden"value="NewsId"/>
- <inputid="Button1"type="submit"value="button"/>
- <ahref="http://www.dwww.cn/News/Display.aspx?NewsId=NewsId">查看更多评论</a></form>
- </div>
- </body>
- </html>
2、前态页面 NewsAdd.aspx,就是一个表单,用来填写新闻的标题和内容。
- <%@PageLanguage="C#"AutoEventWireup="false"validateRequest="false"CodeFile="NewsAdd.aspx.cs"Inherits="NewsAdd.Admin_AdminPanel_NewsAdd"%>
- <%@RegisterTagPrefix="FCKeditorV2"Namespace="FredCK.FCKeditorV2"Assembly="FredCK.FCKeditorV2"%>
- <!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
- <htmlxmlns="http://www.w3.org/1999/xhtml">
- <headrunat="server">
- <title>添加新闻</title>
- </head>
- <body>
- <formid="form1"runat="server">
- <div>
- <asp:LabelID="Label2"runat="server"Text="标题"></asp:Label>
- <asp:TextBoxID="Title"runat="server"Width="325px"></asp:TextBox><br/>
- <asp:LabelID="Label1"runat="server"Text="内容"></asp:Label>
- <FCKeditorV2:FCKeditorid="Content"basePath="~/FCKeditor/"runat="server"Height="400px"Width="70%"></FCKeditorV2:FCKeditor>
- <asp:ButtonID="Button1"runat="server"onClick="Button1_Click"Text="Button"/>
- <asp:LabelID="Message"runat="server"></asp:Label></div>
- </form>
- </body>
- </html>
