Classic ASP and Ajax, without page refresh, Star Rating system


Classic ASP Active Server Pages Examples, code, tutorials, scriptsYvo Schaap's Ajax CSS Star Rating Adapted for Classic ASP

Schaap has a very simple, easy to adapt Ajax star rating system that I adapted for use with Classic ASP.  However, for me, although it works great with MSIE, the css aspects fail with Firefox, so there is something I've overlooked. If you see what it was, please let me know.


Go to Yvo Schaap's tutorial to get the css and js files.
 

ASP Page on which ratings are displayed:

<head>
<script src="rating.js" type="text/javascript"></script>

<table border="0" width="100%" bgcolor="#FFFFFF" style="padding-left: 10px; padding-right: 10px; padding-top: 5px; padding-bottom: 5px">

' Next, the script updates the form inputs retrieved from the querystring into the database table:

' Creating Recordset Object and opening the database
Set rs = Server.CreateObject("ADODB.Recordset")
' Lets open table
'rs.Open "PICTURES", conn, 1, 2, adCmdTableDirect

' No rs.AddNew command needed here since we are only
' updating the records
strsql = "SELECT * FROM [PICTURES] WHERE [PIC_ID]=" & cint(strKey)

rs.Open strsql, conn,3,3

rs("RATING")=rs("RATING")+strRate

' Now updating records

' Done. Now Close the Connection
rs.Close
