[Javascript] Accessing atributes - window.opener

Tue Sep 28 14:31:45 CDT 2004

Just to add my 2¢, here's a sample of something I did recently.
I know it's a day late and a dollar short (98¢ short?), but I just
wondered if it might help someone.

This snippet is a piece of ASP code (vbScript), which writes a
bunch of links from an SQL query.

If rsForm.EOF Then
   toPage "<p>There were no results.  Please try again.</p>"
Else

   regEx.Pattern = "^#(\d{3}).*$"
   storeNum = regEx.Replace(rsForm("deptdesc"), "$1")
   toPage "<table>"
   Do Until rsForm.EOF
      toPage "<tr>"
      toPage "<td><a href=""#"" onclick=""opener.window.document.forms['thisForm'].elements['psid'].value = '" & rsForm("psid") & "';opener.window.document.forms['thisForm'].elements['snum'].value = '" & storeNum & "';opener.window.document.forms['thisForm'].elements['jtitle'].value = '" & rsForm("jtitle") & "';opener.window.document.forms['thisForm'].elements['uname'].value = '" & rsForm("lname") & ", " & rsForm("fname") & "';window.close();"">" & rsForm("lname") & ", " & rsForm("fname") & "</a></td>"
      toPage "<td>"  & rsForm("deptdesc") & "</td>"
      toPage "<td>"  & rsForm("jtitle") & "</td>"
      toPage "</tr>"
      rsForm.MoveNext
   Loop
   toPage "</table>"
End If
