关于模式窗体关闭后刷新主页面的问题

 

1.有些时候用到模式弹出窗体，传递参数。根据应用不同，有的需要在弹出框关闭时刷新父页面， 有的不允许刷新父页面。 

在这里实现的方式，主要是判断模式窗体返回值，可以直接把值填充到父页面控件中（不刷新），也可以让页面刷新取子页面里的Session值 

下面用一个例子说明，有两个页面Default.aspx 和 InputMessage.aspx ,贴代码：

Default.aspx

View Code

Default.aspx.cs

View 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 _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Text = "未登录";
        if (Session["userid"] != null && Session["username"] != null)
        {
            Label1.Text ="<font color='red'>用户编号:"+ Session["userid"].ToString().Trim() + "    用户名:" + Session["username"].ToString()+"</font>";
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "msg", "var r=window.showModalDialog('inputMessage.aspx',{'name':'张三丰','age':88},'dialogWidth=16; dialogHeight=9;scroll=no; status=no;center=yes'); if (r == undefined) window.location=location;", true);

    }
}

InputMessage.aspx

View Code 
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="inputMessage.aspx.cs" Inherits="InputMessage" %>
<html xmlns="http://www.w3.org/1999/xhtml" >

            width: 137px;
        }
    </style>
</head>
<base target="_self" />
<body>
    <form id="form1" runat="server">
    <div>
        <table style="width:100%;" cellpadding="20">

                <td align="center">
        姓名：<input id="Text1" type="text" /><br />
        年龄：<input id="Text2" type="text" /><br />
        <input id="Button1" type="button" value="登录后不刷新" onclick="return GO()" />
        <script type="text/javascript">
            var args=window.dialogArguments;
            document.getElementById('Text1').value=args.name;
            document.getElementById('Text2').value=args.age;
            function GO() {
                window.returnValue = { "user": document.getElementById('Text1').value, "age": document.getElementById('Text2').value };
                window.close();
            }
</script>
               <asp:Button ID="Button2" runat="server" Text="登录后刷新" onclick="Button2_Click"  Height="41px" Width="145px" />
                </td>
            </tr>
        </table>
    </div>
    </form>
</body>
</html>

InputMessage.aspx.cs

View 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 InputMessage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        string userID = "";
        string userName = "";
        //验证登录
        //登录失败-- 继续 
        //登录成功-- 保存Session，更新主页面显示用户信息
        Session.Add("userid", "111");
        Session.Add("username", "小王");
        Response.Write("<script language='javascript'>");
        Response.Write("window.close()");
        Response.Write("</script>"); 
    }
}
