弹出页面之间传值

假如A页面需要弹出B页面,在比页面关闭时,A页面要拿到B页面的需要值;

思路可以认为是:

1.在A页面中利用Window.Open()方法;

<body>
    <form id="form1" runat="server">
    <div>
         <asp:TextBox ID="txtTest" runat="server"></asp:TextBox>
        <input id="Button1" type="button" value="button" onclick="window.open('Default.aspx?', 'b', 'height=450, width=550, top=120, left=262, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no')" />
  </div> </form> </body> </html>

 2.在弹出的B页面中取得相关值,赋给前台的Value;

利用Window.Opener拿到弹出此页面的页面(父页面)中txtTest控件;

然后赋值,关闭页面;

<head runat="server">
    <title>无标题页</title>
    <script language="javascript" type="text/javascript">
        function fun()
        {
            var value=document.getElementById("txtValue").value;
            var txtObjId = window.opener.document.getElementById("txtTest");
            txtObjId.value = value;
            window.opener = null;
            window.close();
        }

    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="txtValue" runat="server"></asp:TextBox>
        <input id="Button1" type="button" value="关闭" onclick="fun()" /></div>
    </form>
</body>
</html>
