Counting links in table rows

[akadeco]

Hi

I need to write a script that will allow me to check the value of any link in a table cell. The desired result would be something like this:

row[0].cell[2].innerHTML

, allowing me to call the contents of the fourth cell in the first row.

The following script may be of use as a starting point:

<table id="table">
<tr>
<td><a href="#">hello1</a></td>
<td><a href="#">hello2</a></td>
</tr>
<tr>
<td><a href="#">hello3</a></td>
<td><a href="#">hello4</a></td>
</tr>
</table>
 
<script type="text/javascript">
window.onload = function() {
    var table = document.getElementById('table');
    var rows = table.getElementsByTagName('tr');
    for (i=0; i < rows.length; i++) {
        var cells = rows[0].getElementsByTagName('td');
        for (j=0; j < cells.length; j++) {
            alert(cells[1].getElementsByTagName('a').innerHTML); // Desired result is hello2 but returns undefined
        }
    }
 
}
</script>

Thanks

Try:

alert(cells[1].getElementsByTagName('a')[0].innerHTML);

getElementsByTa gName() returns a collection.

window.onload = function() {
    var rows = document.getElementsByTagName('tr');
    for (var i=0; i < rows.length; i++) {
        var cells = rows[i].getElementsByTagName('td');
        alert(cells[0].innerHTML);
    }
}

Is what I was after

Thanks
