本文介绍了一个简单的ASP.NET Web页面实例，该页面利用jQuery JavaScript库来读取服务器端设置的一个隐藏字段（hidden field）的值。通过客户端按钮点击事件触发，能够显示上一页地址的值，该值在服务器端被写入到隐藏字段中。

HTML code

<% @ Page Language = " C# " AutoEventWireup = " true " CodeFile = " Default2.aspx.cs " Inherits = " Default2 " %> <! 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 > < script src ="jquery-1.6.min.js" language ="javascript" type ="text/javascript" ></ script > < script language ="javascript" type ="text/javascript" > function GetUrl() { alert(document.getElementByIdx_x_x( ' hidden1 ' ).value); } </ script > </ head > < body > < form id ="form1" runat ="server" > < div > < input id ="Button1" type ="button" value ="获取上一页地址" onclick ="GetUrl();" /> < input id ="hidden1" type ="hidden" value ="" runat ="server" /> <% -- 隐藏域存储上一页地址 -- %> </ div > </ form > </ body > </ html >

C# code

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Default2 : System.Web.UI.Page { protected void Page_Load( object sender, EventArgs e) { if ( ! Page.IsPostBack) { hidden1.Value = Request.UrlReferrer.ToString(); } } }
