弹出选择页面。
弹出选择页面。
功能介绍：点击页面上的某个控件，将数据传入到另一个页面并以弹出窗体的形式弹出。在那个页面做相应处理后回到原始页面，并将处理过的数据传会来。类似Windows的选择窗体。
在基础页面用如下代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SelectForm.aspx.cs" Inherits="WebPage_SelectForm" %><!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>无标题页</title> <script language = "javascript"> function funInput()
{
var varResult; var varInput = document.getElementById("input").innerHTML; //alert(varInput); url = 'SelectedForm.aspx?input='+escape(varInput); varResult = window.showModalDialog(url,[window],'scroll:yes;dialogWidth:500px;dialogHeight:500px;status:0;center:yes'); // alert(varResult.button1); if (varResult != null) 
{
document.getElementById("output").value = varResult.button1; return varResult; 
} 
} </script></head><body> <form id="form1" runat="server"> <div> <asp:Label id = "input" runat = "server" Text="test" >test data</asp:Label> <asp:TextBox ID = "output" runat = "server">aaaaaa</asp:TextBox> <button style="CURSOR: hand; width: 316px; height: 29px;" onclick="funInput()" id="IMG1"/> </div> </form></body></html>注意：对于lable、button这类控件，要获得他们中的数据，要用innerHTML，但是对于textBox这样的控件用Value
下面是要弹出的页面的后台代码：
using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Text;public partial class WebPage_SelectedForm : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { if (Request["input"] != null) { System.Text.StringBuilder sb = new StringBuilder("<script Language="Javascript">"); sb.Append("function setResult(varResult)"); sb.Append("{"); sb.Append("window.returnValue = new result(varResult);"); sb.Append("window.close();"); sb.Append("}"); sb.Append("function result(varResult)"); sb.Append("{"); sb.Append("this.button1 = varResult;"); sb.Append("}"); sb.Append("<"); sb.Append("/"); sb.Append("script>"); if (!ClientScript.IsStartupScriptRegistered("Result")) ClientScript.RegisterStartupScript(this.GetType(), "Result", sb.ToString()); } this.Button1.Attributes.Add("onclick", "javascript:setResult('" +Request.QueryString["input"].ToString()+ "is processed')"); } protected void Button1_Click(object sender, EventArgs e) { }}嘿嘿。。。。只要完成了传递数据的工作，以后想做什么都可以了呀。
