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
