I have used following code to refresh parent window from a popup created by the same.
--------------------------
var strval = "PrjList.asp?searchby=" + document.getElementById("Searchby").value + "&dtFrom=" + document.getElementById("dtFrom").value + "&dtTo=" + document.getElementById("dtTo").value + "&op=" + document.getElementById("op").value;

parent.window.opener.href = strval;

parent.window.opener.location.reload();

window.self.close();
-------------------------------
I originally wanted to :
1. Provide interface to change in popup.
2. As soon as changes are done user clicks button to close popup.
3. Before closing sscript should reload parent with new parameters in popup.
4. popup closed and reloads parent window.

close popup window
