javascript关闭弹出窗体时刷新父窗体和居中显示弹出窗

居中显示用到了moveTO()方法；

关闭弹出窗时刷新父窗体用到了window.opener方法；

父窗体代码例如以下：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="弹出窗体.aspx.cs" Inherits="弹出窗体" %>

<!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 type="text/javascript">

        function cc() {

            var hdc = window.open('ChildWin.aspx', '弹出框', 'width=900,height=450,top=300,left=300');

            width = screen.width;

            height = screen.height;

            hdc.moveTo((width - 900)/2,(height-450)/2);//居中显示

        }

    </script>

</head>

<body >

    <form id="form1" runat="server">

    <div>

        <input id="Button1" type="button" value="button" onclick="cc()"/></div>

    </form>

</body>

</html>

子窗体代码例如以下：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ChildWin.aspx.cs" Inherits="ChildWin" %>

<!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 type="text/javascript">

        function myCheck() {

            alert("关闭子窗体！

");

            window.opener.location.reload();

            window.close();

        }

    </script>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <asp:BulletedList ID="BulletedList1" runat="server" Width="526px">

            <asp:ListItem>1</asp:ListItem>

            <asp:ListItem>2</asp:ListItem>

            <asp:ListItem>3</asp:ListItem>

            <asp:ListItem>4</asp:ListItem>

            <asp:ListItem>5</asp:ListItem>

            <asp:ListItem>6</asp:ListItem>

            <asp:ListItem>7</asp:ListItem>

            <asp:ListItem>8</asp:ListItem>

        </asp:BulletedList>

        <br />

        <input id="Button1" type="button" value="关闭"   onclick="myCheck()"/></div>

    </form>

</body>
