You should be using ClientID property of the serverside controls and document.getElementById method to access your controls using javascript.

You may find this article helpful for generating neat ClientIDs.

Sample html:

<table>
    <tr>
        <td>cellValue</td>
        <td><span id="comboId">combo</span></td>
    </tr>
</table>

Sample javasricpt:

// alerts "cellValue"
alert(document.getElementById("comboId").parentNode.parentNode.cells[0].innerHTML);
