I have a javascript function in which if a user select future date then a pop up will appear and that pop up will contain an text box and a button.The user enter the value in the text box and click on the Button of child pop up.I want to capture those value in the parent window but i m not able to do it.

Below is the javascript which i had written:-

JavaScript

function CheckDateEalier(sender, args)
         {
            var toDate = new Date();
            toDate.setMinutes(0);
            toDate.setSeconds(0);
            toDate.setHours(0);
            toDate.setMilliseconds(0);
            if (sender._selectedDate < toDate)
             {
                alert("You can't select day earlier than today! In Case if you are selecting Previous date then, By default it will take current Date.");
                sender._selectedDate = toDate;
                //set the date back to the current date
                sender._textbox.set_Value(sender._selectedDate.format(sender._format))
            }
            if (sender._selectedDate > toDate) {
                var timeSpent = window.open("EnterTimeSpent.aspx", "List", "scrollbars=no,resizable=no,width=320,height=100");
                document.getElementById('<%=hiddenFieldFutureDateSelectTimeSpent.ClientID %>').value = timeSpent;
                return false;

            }
        }

ASP Code for Child page:-

ASP.NET

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EnterTimeSpent.aspx.cs" Inherits="EmployeeQuotient.EnterTimeSpent" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <title>Enter Time Spent</title>
</head>
<body>
<script language="javascript" type="text/javascript">
 
</script>
    <form id="form1" runat="server">
    <div>
    <table>
    <tr>

    </tr>
    <tr>

You can also return the value on button click

JavaScript

function btnSubmitTimeSpent()
{
window.returnValue="time";
window.close();
}

hi,
add a TextBox on your parent page as

ASP.NET

<asp:textbox id="Txtparent" runat="Server" xmlns:asp="#unknown" />

and set its value from the child page as

JavaScript

window.opener.document.forms[0].getElementById('Txtparent').value ="Value From Popup Page";
