Suppose my Java Script is iterating through a table row and cell
at a time. Meaning accessing the contents of each <td> cell.

I know that I can access the contents of the cell using innerhtml. That works
good when there is data in the cell.

However what if there is a control in the cell. Like a label control for example.
How would I access that control, so that I can get the id of the control?

You see when the java script is iterating through each cell, it has no idea if the
data in each cell is a control or just data, like "Hello World".



<table>
<tr>
<td>Hello World</td>
</tr>

<tr id="outter">
<td id="inner">
<Label id="Label1" Text="Label Control" runat="server"/>
</td>
</tr>

</table>

<td>Hello World</td>
</tr>
<tr id="outter">
<td id="inner">
<Label id="Label1" Text="Label Control" runat="server"/>
</td>
</tr>
</table>
<script>
var theTab = document.getElementsByTagName("table")[0];
var theCell = theTab.rows[1].cells[0];
var theLabels = theCell.getElementsByTagName("label");
alert(theLabels[0].id);
</script>
</body>
</html>
