Hi,

I am new to Javascript. I have a parent window in which i have declared some variables and functions. Using window.open i open the child window and depending on the selection made by user i have to assign values to parent window variables...

Can anybody help me with this..how do i access parent window variables in child form..

Thanks,
Reena

Code snippet below shows the syntax to communicate between parent window and child window.
WHn you open a child window it shows you an alert box with the text value from the parent window.
and onlck on a link on the child page will force to open a the link in the parent window.

<html>
<head>
<title>Interaction with Pop Up Window - child/parent</title>
<script>

function openPopup(){
var popupWin = window.open("Blank.html","popupWin","width=300,height,300,scollbar=no,addressbar=no");
popupWin.document.open();
popupWin.document.write("<script>alert(top.opener.document.frm.txt.value);<\/script><a href=\"javascript:top.opener.document.location.href='http://www.cnn.com';self.close();\"\">Open CNN in parent Frame</a>");
popupWin.document.close();
}
</script>

One Way to get some variables is the following syntax:

window.opener.yourForm.YourField.value;
