JavaScript – Working with Database

After reading this coding, you will know the following facts.

  1. How to connect the database in JavaScript
  2. How to use the ADODB.Recordset in JavaScript

As I already put the details comments in coding, I hope you will find it useful.

You can download the sourcecode and MSAccess database from this link.


<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns=
"" xml:lang="en" lang="en">
<script type
var adOpenDynamic = 2;
var adLockOptimistic = 3;

/* Path of database.
If you put the database "Inventory.mdb" in different location,
you need to specify the correct path to this variable.
But When you are running the webpage from Browsers only,
you should use this keyword "window.location.pathname" for getting
the current location. But If you are using FrontPage,
you hav to specity the static path.
var strDbPath = "C:\\JavaScript Database\\Inventory.mdb";

Here is the ConnectionString for Microsoft Access.
If you wanna use SQL or other databases, you hav
to change the connection string..
eg: SQL => var conn_str = "Provider=sqloledb; Data Source=itdev;" +
"Initial Catalog=pubs; User ID=sa;Password=yourpassword";
var conn_str = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strDbPath;

function getAdoDb(strAdoType){
if (window.ActiveXObject){
return new ActiveXObject(strAdoType);
return new ActiveXObject(strAdoType);

function showReports(){
var strHtml ="";
strHtml += "<table cellpadding=0 cellspacing=0 border=1 width=500px align=center>";
strHtml += "<tr ><td align=center colspan=4><b>Stock List</b></td></tr>";

//Database Connection
var conn = getAdoDb("ADODB.Connection");, "", "");

var rs =
strQuery = "SELECT StockID,StockName,ReOrderLevel,IsActive FROM Stocks";, conn, adOpenDynamic, adLockOptimistic);

while(!rs.eof) {
strHtml += "<tr>";
strHtml += " <td width=\"10px\">" + rs.fields(0).value + "</td>";
strHtml += " <td width=\"50px\">" + rs.fields(1).value + "</td>";
strHtml += " <td width=\"10px\">" + rs.fields(2).value + "</td>";
strHtml += " <td width=\"5px\">" + rs.fields(3).value + "</td>";
strHtml += "</tr>";

//No Records.
strHtml += "<tr colspan=4><td align=center><font color=red>No Records.</font></td></tr>";
strHtml += "</table>";

Stock List</title>

  2. Hi Alice, Sorry for very very late response.. I was so busy these days and couldn’t have that much time to take a look it.. actually, using ActiveX is not good one..

    Hi basanthi, using activex is not very good idea. So, Could you please do it with Ajax?

  3. hai
    I wrote the same code as above. Frontend is HTML, Backend is MS-access. we are having a group of linking forms,in first form data is storing in access and from second form data is not storing in access. Where am i going wrong Please help me.

  4. You should probably tell me what error you got or etc.. With your question, I’m not sure how I can help you.. The most of problems are already discussed in old comments so if you read each and every comments in this post, you may probably solve the problem… one more thing… I suggest not to use ActiveX object as much as possible.. Aax can do better..

  5. i wrote the code in the same format as above.
    when i enter values in form it is storing in database.And after completion of that file entry it is closingi.e.., the browser is collapsed.
    MY requirement is it should find the existing record and should enter the fields which are kept empty

  6. hi i got this error “ActiveX object not defined”…….
    How to rectify this error????????

  7. Hello,

    I want to create a very simple web application that will display the rows of a particular database table. However I also want the application to display new entries into the table, as they are inserted. Is there an easy way to determine when a new row has been inserted?


  8. To Michael Sync,

    I have a program that I’ve created completely in javascript (html wrapped in an ebook exe program) that people love except for the fact that they need to complete all the tasks within my program to create their project; many of them have said they would like the ability to input some data and then return to the program and have the program automatically fill-in what data they inputted previously.

    I know cookies will not work, because they will not hold enough data; is it possible to have some kind of javascript database within the program that the software could auto write to and auto retrieve from.

    I’ve never worked with databases, but if this is something that can be done, I’m willing to pay for it.


  9. Hi,

  10. Hi Michael,

    I know there is a long time to this artical , but realy I need your example

    Thank you

  11. hi Michael,
    You are really great.I was actually struggling for the last two other forums ..i was told that we need to use server side scripting even when db is located locally..great effort..and effort appreciated.

  12. i want to check onblur of a text box.when i click outside the text box.that time it will check in database filled value is existing in database or not…for that what can i do?

  13. Hi Mike,
    I was able to run this code locally on windows platform, but when I put it into the server, It didn’t work. I am getting the following message
    “the connection cannot be used to perform this operation. It is either closed on invalid in this context”.

    Does the connection string need to be specified differently ? I updated the path for the var strDbPath (used /folder/file.mdb), but kept everything else same for var conn_str.
    var conn_str = “Provider=Microsoft.Jet.OLEDB.4.0;Data Source=” + strDbPath.

    Would you know how to resolve this error. I can be reached at

  14. Hi,

    I found this code and it is working great, when the path to file is specified on an Harddisk. But how can I get this code working with a database placed on the server, e.g. http://myserver/mydatabase/database.mdb?

    Anyone who got this working?

    Any help would be appreciated.

    Best Regards,

  15. Hi,

    I tried the code and it is working fine as long as the .mdb is specified with an absolute path. But when I try to use only the Database name, because it is located in the same folder as the .htm or when I try to use the Intranetlink it does not work. Does this not work at all or am I doing something wrong?

    Best Regards,

  16. Sorry, for posting again. I checked this site again and did not find my comment. So I thought maybe something went wrong.

    I am really sorry.
