Hi,

I have a page which connects to an access database using asp / vbscript.


In the head of the page is a javascript for dealing with multiple dynamic drop down menus:

<script type="text/javascript">
<!--

    }
  }
  CitySelect.selectedIndex = 0

}
//-->
</script>


I am trying to find a way to populate the arrays (at the top of the script) dynamically with values from my access database.

Each array would come from a different recordset, and i have no problem sorting these out. I just need to know how I can put a field from the recordset in the array, followed by a comma, followed by the next record, followed by a comma, follwed by etc etc untill there's no records left.

Any ideas would be greatly appreiciated.

Thanks in advance

Paul

Hey Paul - try this:

(example given for populating arrSSRange = ["SS065", "SS100", "SS150", "SS200", "SS3000"])

--------------------------------
'make sure to create a recordset or whatever here
<html>
<head>
</head>
<body>
arrSSRange = ["<% Do Until Recordset.EOF
Response.Write Recordset.Fields(1)
%>","<% Recordset.Movenext
Loop %>"]

</body>
</html>

Hi Paul,

You could try something like this :

<script type="text/javascript">
<!--
var arrMG

<%
' Server-Side ASP/VBScript code
Dim objConn, strSQL, objRS
' create a connection to the Access database
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.Mappath("filename.mdb")

strSQL = "SELECT field FROM table;"
Set objRS = CreateObject("ADODB.Recordset")
objRS.Open strSQL, objConn
' if there is at least one record, write the first element in the JavaScript array
If NOT objRS.EOF Then
  Response.Write "arrMG = [""" & objRS("field") & """"
  objRS.MoveNext
  ' if there are more records, loop through them and add them to the JavaScript array
  Do While Not objRS.EOF
    Response.Write " , """ & objRS("field") & """"
    objRS.MoveNext
  Loop
  ' close the JavaScript array and insert a carriage return
  Response.Write "]" & vbCrLF
End If
' clean up the objects
objRS.Close
Set objRS = Nothing

' clean up the objects
objConn.Close
Set objConn = Nothing
%>

//-->
</script>

This should output the following to the browser :

<script type="text/javascript">
<!--
var arrMG
arrMG = ["MG05LED" , "MG07LCD", "MG10LCD"]
//-->
</script>

For each JavaScript array that you are pulling out of the database, you will need to create another strSQL and objRS object, and loop through them like the one above.

Hope that helps,
 - Splat

Heres my contribution, this would need to be done for each RecordSet that you have...

If not rsList.EOF then
      Response.Write "<script language='JavaScript'>" & vbCRLF
      Response.Write "<!--" & vbCRLF
      Response.Write "arrMG = [" & Chr(34) & rsList("FieldName") & Chr(34)
      
      rsList.MoveNext
      
      If not rsList.EOF then
            Do while not rsList.EOF
                  Response.Write "," & Chr(34) & rsList("FieldName") & Chr(34)
                  
                  rsList.MoveNext
            Loop
      End If
      
      Response.Write "]" & vbCRLF
      Response.Write "//-->" & vbCRLF
      Response.Write "</script>" & vbCRLF
End If
