• Asp.net生成静态页面并对内容分页


    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。

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
        <title>Title</title>
    </head>
    <body>
        <div style=" 417px; height: 54px" align="center">
            <br />
            Title</div>
        <div style=" 417px; height: 8px">
            浏览<font color="red"><script src="http://localhost/.Net/NewsFiles/ClickCount.aspx?NewsId=NewsId"></script></font>次
            Time</div>
        <div style=" 417px; height: 100px">
            Content</div>
        <div style=" 416px; height: 9px">
            Pager</div>
        <div style=" 416px; height: 8px">
            <form id="form1" action="../AddComment.aspx" style="margin: 0px">
            <input id="Text1" type="text" /><img id="Image1" src="http://www.dwww.cn/UserInfo/CheckCode.aspx" /><br />
            <textarea id="CommentContent" cols="20" rows="2"></textarea>
            <br />
            <input id="NewsId" type="hidden" value="NewsId" />
            <input id="Button1" type="submit" value="button" />
            <a href="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。

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="NewsAdd.aspx.cs" Inherits="NewsAdd" %>
    
    <%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title>添加新闻</title>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
            <asp:Label ID="Label2" runat="server" Text="标题"></asp:Label>
            <asp:TextBox ID="Title" runat="server" Width="325px"></asp:TextBox><br />
            <asp:Label ID="Label1" runat="server" Text="内容"></asp:Label>
            <FCKeditorV2:FCKeditor id="Content" basePath="~/FCKeditor/" runat="server" Height="400px"
                Width="70%">
            </FCKeditorV2:FCKeditor>
            <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
            <asp:Label ID="Message" runat="server"></asp:Label></div>
        </form>
    </body>
    </html>
