Dynamically adding javascript with createElement('script')

I have this code below where I'm dynamically adding rows to a table...

I have 9 cells from 0 - 8.

This code works up to a point with no errors:

This is where it somewhat fails: //Set the javascript for the Combo Box :: See Below.

After the dynamic creation of the combo box I need to have the following script added to CELL 5 in the table, row after new row.

<script>
var z=dhtmlXComboFromSelect("cmStds");
</script>

That's it.

       //Standard Select Box
       var cellStandard = row.insertCell(5);
       var celS = document.createElement('select');
       celS.name = 'standard' + iteration;
       celS.id = 'standard' + iteration;
       celS.size = 1;
       celS.style.fontSize = '10px';

       cellStandard.appendChild(celS);


       var option = document.createElement('option');
       option.value = '0';
       option.appendChild(document.createTextNode("Select One"));

       celS.appendChild(option);

       <% while (!cmStd.EOF) { %>
       var option = document.createElement('option');
       option.value = '<%=(cmStd.Fields.Item("cm_std_id").Value)%>';
       option.appendChild(document.createTextNode('<%=(cmStd.Fields.Item("cm_stand_txt").Value)%>'));

       celS.appendChild(option);

       <% cmStd.MoveNext(); } if (cmStd.CursorType > 0) { if (!cmStd.BOF) projs.MoveFirst(); } else { cmStd.Requery(); } %>

       //Set the javascript for the Combo Box      - THIS IS WHAT'S NOT WORKING!
             var ss = document.createElement('script');
            ss.type = 'text/javascript';
            ss.language = 'javascript';
            ss.text = "var z = dhtmlXComboFromSelect('cmStds" + iteration + "');";
            ss.defer = true;
            var tt = document.createTextNode(ss);
            cellStandard.appendChild(tt);

Instead of the script being written I get this:

[object HTMLScriptElement]

I just need to dynamically write this:

<script>
var z=dhtmlXComboFromSelect("cmStds");
</script>

Every time I add a new row. that's pretty much it.

This is close but no cigar... here's the ENTIRE function... which is called when the user presses the "ADD ROW" button. The line in BOLD is where the function MUST be dynamically written.

It can't be done on the window.onload. It must appear in the DOM everytime a new row is created.

Thanks....

      function addRowToTable()
      {
       var tbl = document.getElementById('dataTable');
       var lastRow = tbl.rows.length;

       // if there's no header row in the table, then iteration = lastRow + 1
       var iteration = lastRow;
       var row = tbl.insertRow(lastRow);
       //BEGIN CREATION of the cells of the table

       // Req'd Checkbox
       var cellReqd = row.insertCell(0);
       var reqd = document.createElement('input');

no difference, onload was just for test page.

I still get: [object HTMLScriptElement] next to the Combo Box... no more errors, just the editable combo box doesn't work... I got the editable combo box from www.dhtmlx.com. It's free, so if you want to test it with the code I wrote, you can download the editable combo box. Create a table, call the combo box in CELL ZERO for testing, and eliminate all the rest of the code in the "addRowToTable()" function. Create a BUTTON and onclick call the addRowToTable(). DO NOT put the btnADD in the same table as the combo box. You have to create two tables... give it an ID of dataTable and create a header row.

Here's the DELETE row script:

      function removeRowFromTable()
      {

       var rows;

       var curRows = document.getElementById("MM_ROWCOUNT").value;
       if(curRows == null || curRows == 0) { curRows = rows }
       //alert(curRows);

       var tbl = document.getElementById('dataTable');
       var lastRow = tbl.rows.length;
       //alert(lastRow);

       if (lastRow > 2) tbl.deleteRow(lastRow - 1);

      }

put a HIDDEN field somewhere on your form: <input name="MM_ROWCOUNT" id="MM_ROWCOUNT" type="hidden" /> This is for the DOM to keep count of the new and deleted rows...

The script:

<script>
var z=dhtmlXComboFromSelect("cmStds");
</script>

MUST appear "AFTER" the combo box WITHIN the same cell as the combo box.

Got it to work... you won't believe what the problem was....

Look below and see if you can find it....

       //Standard Select Box
       var cellStandard = row.insertCell(5);
       var celS = document.createElement('select');
       celS.name = 'standards' + iteration; <-- if you look here... I'm calling the element STANDARDS
       celS.id = 'standards' + iteration; <-- and HERE TOO!!!!
       celS.size = 1;
       celS.style.fontSize = '10px';
       celS.style.width = '125px';

       cellStandard.appendChild(celS);


       var option = document.createElement('option');
       option.value = '0';
       option.appendChild(document.createTextNode("Select One"));

       celS.appendChild(option);

       <% while (!cmStd.EOF) { %>
       var option = document.createElement('option');
       option.value = '<%=(cmStd.Fields.Item("cm_std_id").Value)%>';
       option.appendChild(document.createTextNode('<%=(cmStd.Fields.Item("cm_stand_txt").Value)%>'));

       celS.appendChild(option);

       <% cmStd.MoveNext(); } if (cmStd.CursorType > 0) { if (!cmStd.BOF) projs.MoveFirst(); } else { cmStd.Requery(); } %>

       //Set the javascript for the Combo Box

            var ss = document.createElement('script');
            ss.type = 'text/javascript';
            ss.language = 'javascript';
            ss.text = "var z = dhtmlXComboFromSelect('cmStds" + iteration + "');"; <--- THIS IS THE REAL NAME OF THE ELEMENT (cmStds)
            ss.defer = true;
            cellStandard.appendChild(ss);

Once I fixed that... it worked....
