VS2008(C#)制作网页Tab标签切换方法（四）
VS2008(C#)制作网页Tab标签切换方法（四）——IFrame实现
利用HTML的iframe属性，并结合后台的CS代码实现，具体做法如下：
前台HTML代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Main_Page.aspx.cs" Inherits="Tab_Tab_IFrame_Main_Page" %>
<!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 runat="server"> <title>Main_Page</title> <style type="text/css"> body { color: #000000; background-color: #ffffff; font-family: Tahoma, 宋体; font-size: 12px; margin: 0px; padding: 0px; text-align: center; } .aaa { background-color: #ffcc33; } .bbb { background-color: #99ffcc; } </style> </head> <body> <form id="form1" runat="server"> <div style=" margin-top: 20px;"> <asp:Button ID="Button1" runat="server" CssClass="aaa" Text="文学" onclick="Button1_Click" /> <asp:Button ID="Button2" runat="server" CssClass="bbb" Text="科技" onclick="Button2_Click" /> <asp:Button ID="Button3" runat="server" CssClass="bbb" Text="军事" onclick="Button3_Click" /> <br /> <iframe id="IFrame" runat="Server" style=" border: solid 1px inherit; width: 300px; height: 500px;"> </iframe> </div> </form> </body> </html>
后台CS代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;
public partial class Tab_Tab_IFrame_Main_Page : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { IFrame.Attributes.Add("src", "page1.aspx"); Button1.CssClass = "aaa"; Button2.CssClass = "bbb"; Button3.CssClass = "bbb"; } protected void Button1_Click(object sender, EventArgs e) { IFrame.Attributes.Add("src", "page1.aspx"); Button1.CssClass = "aaa"; Button2.CssClass = "bbb"; Button3.CssClass = "bbb"; } protected void Button2_Click(object sender, EventArgs e) { IFrame.Attributes.Add("src", "page2.aspx"); Button1.CssClass = "bbb"; Button2.CssClass = "aaa"; Button3.CssClass = "bbb"; } protected void Button3_Click(object sender, EventArgs e) { IFrame.Attributes.Add("src", "page3.aspx"); Button1.CssClass = "bbb"; Button2.CssClass = "bbb"; Button3.CssClass = "aaa"; } }
附加说明：
在同一目录下，新建三个ASPX网页，命名依次为: Page1.aspx、 Page1.aspx、 Page1.aspx
具体代码如上，源代码下载： VS2008（C#）4种方法实现Tab标签灵活切换源码，测试成功！
