.aspx代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="图片浏览.aspx.cs" Inherits="图片浏览" %>
<!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">
<script src="jquery-1.8.3.js" type="text/javascript"></script>
<title></title>
<script type="text/javascript">
$(document).ready(function () {
$("#lb_img").click(function () {
$("#img2").attr("src", $(this).val());
$("#Text1").val($(this).val());//在页面刷新的过程中,图片的src属性不会被保留而文本内容可以保留
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ListBox ID="ListBox1" runat="server" DataSourceID="AccessDataSource1"
DataTextField="img_fname" DataValueField="src"
AutoPostBack="True"
onselectedindexchanged="ListBox1_SelectedIndexChanged" Height="135px"></asp:ListBox>
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="~/mdb/EV.mdb"
SelectCommand="SELECT img_fname, img_folder + ‘/‘ + img_fname AS src FROM T_IMGMNG">
</asp:AccessDataSource>
<asp:Image ID="Image1" runat="server" Width="216px" />
<br />
<hr />
<asp:ListBox ID="lb_img" runat="server" DataSourceID="AccessDataSource1"
DataTextField="img_fname" DataValueField="src"
注释:这里的AutoPostBack属性要去掉
onselectedindexchanged="ListBox1_SelectedIndexChanged" Height="124px"></asp:ListBox>
<asp:AccessDataSource ID="AccessDataSource2" runat="server"
DataFile="~/mdb/EV.mdb"
SelectCommand="SELECT img_fname, img_folder + ‘/‘ + img_fname AS src FROM T_IMGMNG">
</asp:AccessDataSource>
<img id="img2" width="240" alt="" />
<input id="Text1" type="text" runat="server" />
</div>
</form>
</body>
</html>
.aspx.cs代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class 图片浏览 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { Image1.ImageUrl = ListBox1.SelectedValue; } }
在页面刷新的过程中,图片的src属性不会被保留而文本内容可以保留
效果如下:
