Reference to another column id in a javascript

Question

Hi
I have created a tabular form a 4 uptatable fields and a 5th item as a link. This link is calling a javascript in which a want to refer one of the updatable colums in the same row as the calling link e.q. id="f03_0003". (Row no 3)
The link itself don't get any id.
How do I do that ?

Hi Klaus,
You can retreive the values by determining what row the link is on and then checking all the INPUT items in that row.
Assume that your link is:
<a href="#" onclick="javascript:showValues(this);">Click</a>Then add the following into the page's HTML Header setting:
<script type="text/javascript">
function showValues(xxx)
var p = xxx.parentNode;
while (p.tagName != 'TR')
  p = p.parentNode;
var f = p.getElementsByTagName("INPUT");
var f01 = f[0];
var f02 = f[1];
var f03 = f[2];
var f04 = f[3];
var s = "Values on this row:\n\n";
s += f01.value + "\n";
s += f02.value + "\n";
s += f03.value + "\n";
s += f04.value + "\n";
alert(s);
</script>When you click on a link, the script will work out what TR (that is, Row) the link is on and then create a collection of all INPUT items on that row. Assuming that your f01, f02 etc items are in order, then f[0] should refer to the "f01" item on the same row.
