一:写个工具类,先引用Newtonsoft.Json.dll,用其序列化对象.
using
System;
using
System.Collections.Generic;
using
System.Text;
using
System.Web.UI;
using
Newtonsoft.Json;
using
System.Web;

namespace
*****
.Core.Common

...
{

/**//// <summary>
/// 弹出窗口工具类
/// </summary>
/// <remarks>
/// 实现了弹出窗口返回对象的封装方法
/// </remarks>
/// Title: PopUpWindow
public class PopUpWindow

...{

/**//// <summary>
/// 将对象返回给调用页面
/// </summary>
/// <param name="entity">需要返回的对象实例</param>
/// <param name="page">调用此方法的page本身</param>
public static void ReturnObject(Object entity, Page page)

...{
//使用JSON序列化对象
string output = String.Format("var retObj = {0};", JavaScriptConvert.SerializeObject(entity));
//注册脚本到弹出窗口以返回序列化后的对象
Type cstype = HttpContext.Current.GetType();
ClientScriptManager cs = page.ClientScript;
//将实体返回给调用方caller
String csname1 = "CloseScript";
if (!cs.IsStartupScriptRegistered(cstype, csname1))

...{
String cstext1 = String.Format("{0} window.returnValue = {1};window.close();", output, "retObj");
cs.RegisterStartupScript(cstype, csname1, cstext1, true);
}
}
}
}
二:二:在公共页某按钮事件里设置返回数据,例如:
protected
void
Button1_Click1(
object
sender, EventArgs e)

...
{
//创建需要返回的实体对象
SampleEntity entity = new SampleEntity();
entity.ProjectNo = TextBox1.Text;
entity.ProjectName = TextBox2.Text;

//将对象返回给调用页面
PopUpWindow.ReturnObject(entity, this);


/**//**//**/////创建需要返回的实体对象列表
//SampleEntity entity1 = new SampleEntity();
//entity1.ProjectNo = TextBox1.Text;
//SampleEntity entity2 = new SampleEntity();
//entity2.ProjectNo = TextBox2.Text;

//List<SampleEntity> list = new List<SampleEntity>();
//list.Add(entity1);
//list.Add(entity2);

/**//**//**/////将对象返回给调用页面
//PopUpWindow.ReturnObject(list, this);
}
三:在调用页放置一客户端图片控件,例如: 然后在客户端脚本中加入如下代码即可,建议以模式窗口打开.
<
img
src
="../images/lookup.gif"
onclick
="OnQueryClick()"
id
="btnImage"
alt
="点击我!"
tyle
="cursor: hand"
/>
//获得弹出窗口的返回对象

<
script
type
="text/javascript"
>
...
function OnQueryClick()

...{
var address = "test.aspx";
var parameter1 = "";
var OpenStyle = "dialogWidth:650px;dialogHeight:550px;dialogLeft:200px;dialogTop:150px;center:yes;help:false;resizable:false;status:false";
var returnValue = window.showModalDialog(address,parameter1,OpenStyle);
//分别获取返回对象的属性
if(returnValue != null)

...{
document.getElementById("ctl00$ContentPlaceHolder1$txtProjectNo").value = returnValue.ProjectNo;
document.getElementById("ctl00$ContentPlaceHolder1$txtProjectName").value = returnValue.ProjectName;
}
}
</
script
