Very silly and easy question but my brain isn't working today
How can i get the last row of a table (table id=foo) ...
Tables have a rows collection that includes all rows in the table.
Try:
var rows = document.getElementById(tableID).rows;
var lastRow = rows[rows.length -1];
Or if you want something much faster in IE:
var rows = document.getElementById(tableID).getElementsByTagName
('tr');
var lastRow = rows[rows.length -1];

The row is inserted dynamically via an ajax request so its not on the
page at load time!.
$('foo').select('tr:last');
Unlike jQuery, Prototype.js uses standard CSS selectors only.
Try
$$('#footr:last-child');
Why $$('#foo') and not $('foo').select()?
If you had some nested tables inside table#foo, then the select clause
would return last rows of each of those nested tables along with the
last row of foo table.
Please also take note, that if you have tbody, thead or tfoot elements
in the table then you will get one tr per each of that elements.
Even if you have not tbody in your html, current browsers might create
one dynamically for you, in the process of html error correction.
This, however, should not be a problem since ther would be only one
tbody for the table.
If you have more than one tbody, then try this:
$$('#footbody:last-childtr:last-child');
If you have also a tfoot, then use tfoot in the above.
Best regards,
SWilk
