本文实例为大家分享了基于jQuery实现点击小图显示大图效果,供大家参考,具体内容如下

显示以下效果

点击任意一张图片会显示大图

1、前台界面

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="练习.WebForm1" %><!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></title>   <style type="text/css">   #mydiv ul{ list-style-type:none;}   #mydiv ul li{ display:inline;}   #mydiv{ width:500px; border:solid 1px #444; background-color:#333;}    </style>   <link href="css/nf.lightbox.css" rel="stylesheet" type="text/css" />   <script src="Jquery1.7.js" type="text/javascript"></script>   <script src="js/NFLightBox.js" type="text/javascript"></script>   <script type="text/javascript">    $(function () {     //var settings = { containerResizeSpeed: 3000 };     $('#mydiv ul a').lightBox({ containerResizeSpeed: 1000 });    })     </script></head><body><form id="form1" runat="server"> <div id="mydiv" runat="server">  </div> </form></body></html>

2、后台代码

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Data.SqlClient;using System.Data;using System.Text;namespace 练习{ public partial class WebForm1 : System.Web.UI.Page {  protected void Page_Load(object sender, EventArgs e)  {   if (!IsPostBack)   {    LoadData();   }  } private void LoadData()   {   string constr = "data source=LOVE-PC//SQLEXPRESSPC;initial catalog=BoKe;user id=sa;password=admin";   using (SqlConnection conn = new SqlConnection(constr))   {    using (SqlCommand cmd =conn.CreateCommand())    {     conn.Open();     cmd.CommandText = "select BigImgUrl,SmallImgUrl from T_Photo";     SqlDataAdapter adapter = new SqlDataAdapter(cmd);     DataTable dt = new DataTable();     adapter.Fill(dt);     StringBuilder sb = new StringBuilder();     sb.Append("<ul>");     for (int i = 0; i < dt.Rows.Count; i++)     {      sb.Append("<a href=" + dt.Rows[i]["BigImgUrl"] + ">");//添图片路径      sb.Append("<li>");      sb.Append("<img src=" + dt.Rows[i]["SmallImgUrl"] + ">");//添图片路径      sb.Append("</li>");      sb.Append("</a>");     }     sb.Append("</ul>");      mydiv.InnerHtml = sb.ToString();    }   }     } }}
