Using an ajax datatable in classic asp

I am trying to incorporate a datatable into my classic asp page and I am having a difficult time with the variable declaration, especially array dimensions.  Not sure if this should be done in the "main" page or in the page that creates the array.  Does it work like an include?  Here is my call to the data:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="/drop_menu/menu.css"> 

<!-- DataTables CSS -->
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.1/css/jquery.dataTables.css">
  
<!-- jQuery -->
<script type="text/javascript" charset="utf8" src="//code.jquery.com/jquery-1.10.2.min.js"></script>
  
<!-- DataTables -->
<script type="text/javascript" charset="utf8" src="//cdn.datatables.net/1.10.1/js/jquery.dataTables.js"></script>

<script type="text/javascript">
$(document).ready(function() {
    $('#standings').dataTable( {
        "ajax": '/get_results.asp?series_id=<%=lSeriesID%>&gender=<%=sGender%>&year=<%=iYear%>&age_to=<%=iAgeTo%>'
    } );
} );
</script>

Open in new window


On the same page, here is my html:
                    <table id="standings" class="display" cellspacing="0" width="800px">
                        <thead>
                            <tr>
                                <th valign="bottom">Pl.</th>
                                <th valign="bottom">Name</th>
                                <%For i = 0 To UBound(SeriesRaces, 2) - 1%>
                                    <th style="text-align: center;width: 75px;white-space: nowrap;" valign="bottom"><%=SeriesRaces(1, i)%></th>
                                <%Next%>
                                <th valign="bottom">Total</th>
                            </tr>
                        </thead>
                        <tbody>
                            <%For i = 0 To UBound(Results, 2) - 1%>
                                <tr>
                                    <%If Results(14, i) = "0" Then Exit For%>

                                    <%If i mod 2 = 0 Then%>
                                        <td class="alt"><%=i + 1%>)</td>

What should be declared/dimensioned the "get_results.asp" page and what should be in this page?

I think you are trying to mix up server side and client side.

Looking at the sample, you only need the table head and footer in your html.    http://www.datatables.net/examples/data_sources/ajax.html

<table id="example" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Extn.</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </thead>
 
        <tfoot>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Extn.</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </tfoot>
    </table>

Open in new window

They show the output like this
{
  "data": [
    [
      "Tiger Nixon",
      "System Architect",
      "Edinburgh",
      "5421",
      "2011/04/25",
      "$320,800"
    ],
    [
      "Garrett Winters",
      "Accountant",
      "Tokyo",
      "8422",
      "2011/07/25",
      "$170,750"
    ]
]
}

For this very sample output, you can see how I created the objects here http://www.experts-exchange.com/Programming/Languages/Scripting/ASP/Q_28469969.html#a40206249
<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<%Response.Buffer = false%>
<!-- #include file="db_connection.inc" --> 
{"data": [
<%

Set oConn=Server.CreateObject("ADODB.Connection") 
oConn.Open strConnect
strSQL1 = "SELECT top 50 dbo.Artists.artistname, dbo.Recordings.RecordingTitle, dbo.Tracks.TrackTitle, dbo.Tracks.TrackFileName FROM  dbo.Artists INNER JOIN dbo.Recordings ON dbo.Artists.artistid = dbo.Recordings.ArtistID INNER JOIN dbo.Tracks ON dbo.Recordings.RecordingID = dbo.Tracks.RecordingID "
Set oRs1=oConn.Execute(strSQL1,lngRecs,1)


' send data to an array'
if not oRs1.eof then
	myArray=oRs1.getrows()
end if

oRs1.Close
Set oRs1 = Nothing
oConn.Close
Set oConn = Nothing



for r = LBound (myArray,2) to UBound(myArray,2)
	artistname 		= myArray(0, r)
	RecordingTitle 	= myArray(1, r)
	TrackTitle 		= myArray(2, r)
	TrackFileName 	= myArray(3, r)

	TrackFileUrl = replace(TrackFileName,"M:\Music\","\mp3\")

	'M:\Music\MP3MusicAlbums\!!!\Louden Up Now\01-Louden Up Now-When The Going Gets Tough The Tough Gets Krazee.mp3

	' convert to'
	'\mp3\MP3MusicAlbums\!!!\Louden Up Now\01-Louden Up Now-When The Going Gets Tough The Tough Gets Krazee.mp3

	TrackFileLink = "<a href="&"[x]"&TrackFileUrl&"[x]"&">"&TrackTitle&"</a>"

    theURL = replace("["&chr(34)&artistname&chr(34)&","&chr(34)&RecordingTitle&chr(34)&","&chr(34)&TrackTitle&chr(34)&","&chr(34)&TrackFileLink&chr(34)&"]","\","\\")
    theURL = replace(theURL,"[x]","\"&chr(34))
    response.write theURL

        if r < UBound(myArray,2) then
    	response.write ","
    end if


next

The above is using getrows to make the array.  To make a nice json, you have to escape some characters such as slashes.  Run your asp page that generates the output and use a linter to see if the output is in correct form.   http://jsonlint.com/

Notice there is no looping in the main page, that is taken care of by the datatables js code.

Go back the super simple sample I showed you and start adding your own data and table.  If it does not work, more than likely it is the forming of the json.

On the output page, surf to your url below replacing your asp tags for hard coded data.  Then put the results to the linter and that is a good first step.
/get_results.asp?series_id=<%=lSeriesID%>&gender=<%=sGender%>&year=<%=iYear%>&age_to=<%=iAgeTo%>

This is what your table should be although I would get rid of the inline styles for now.  The variable table headings we can update with jquery.  For now, leave them hard coded with something.

 <table id="standings" class="display" cellspacing="0" width="800px">
                        <thead>
                            <tr>
                                <th valign="bottom">Pl.</th>
                                <th valign="bottom">Name</th>
                                <!-- TO DO: allow jquery to update text -->
                                    <th style="text-align: center;width: 75px;white-space: nowrap;">title to be changed later</th>
                                <th valign="bottom">Total</th>
                            </tr>
                        </thead>
                        <!-- remove tbody -->
                        <tfoot>
                            <tr>
                                <th rowspan="2" valign="bottom">Pl.</th>
                                <th rowspan="2" valign="bottom">Name</th>
                                <!-- TO DO: use jquyer to update data text -->
                                    <th style="text-align: center;width: 75px;" valign="bottom"></th>
                                
                                <th valign="bottom">Total</th>
                            </tr>
                        </tfoot>

Ok, now we need to work on your front end. I am pretty tied up today.  I will take a look later.  We need to set this up so jquery grabs what is in the drop down and sets some of the dynamic features instead of using serverside asp.

Ok so I am starting to get through this.  Here is my question:  what is in this text file and how is it created?  Is that a text file created from the asp (file system object) using the data in the array?

"ajax": '../ajax/data/arrays.txt'

I'm going to close this one out and re-focus the question because I have made a ton of progress.
