    Problems connecting to Access 2007 database with JavaScript

    I am trying to create a form that will generate a query, send that query to a database, and display the results on a Web page. For now, the form fields don't actually contribute anything to the code, they just sit there as placeholders. What I want to do for now is this: connect the page to the database, run a hard-coded query, and have the results displayed in table form on the page. I want the database to be a .accdb (Access 2007) file that is located on the server. I have been using JavaScript to do this.

    Here is what I have so far:

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>School of CIS TCPT</title>
    
    <script language="JavaScript" > 
    
    function getSubmit() 
    { 
    var ClassID;
    var CreditHours;
    
    var cn = new ActiveXObject("ADODB.Connection");
    var strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source = classes.accdb;Persist Security Info=False"; 
    var rs = new ActiveXObject("ADODB.Recordset");
    var SQL = "SELECT 0910.ClassID, 0910.CreditHours FROM 0910"; 
    var resultSet = strConn.query(SQL);
    cn.Open(strConn); 
    rs.Open(SQL, cn); 
    ClassID.value = rs(0); 
    CreditHours.value = rs(1);
    rs.Close(); 
    cn.Close(); 
    
    } 
    
    </script> 
    
    <link href="style.css" rel="stylesheet" type="text/css" />
    
    <style type="text/css">
    <!--
    .style2 {color: #c80000}

    </style>
    </head>

        <td>&nbsp;</td>
      </tr>
    </table>
    
    </body>
    
    </html>
    I have tried adding things like "alert("test");" etc. to the Submit button just to see if the code was working. No dice. I click on the button, and nothing happens. So I tried creating a little "document.write("Hello World!");" to see if JavaScript itself was even working, and the Hello World DID work. So obviously, something is wrong with my code.

    Help? Advice? How do I make this work?

    Hi,
    I have attached an working example that i created. You should be able to modify the html behind it to suit your requirements.
