count the number of rows in the table

I would like to be able to write a function (or something) to count the number of rows in the table, I don't know how to do it, any help is appreciated.

var rowCount = document.getElementById("tableID").getElementsByTagName("TR").length;
alert(rowCount);

Hi,
But this method throws a "Object Required" error and opening a new browser window.What can be the reason behind this?

Thanks,
Anil

It works just fine for me. :)

alert(document.getElementById('yourTableID').rows.length);

alert(document.getElementById('yourTableID').rows.length);
It absolutely the same as glenngv posted

alert(document.getElementById('yourTableID').getElementsByTagName('tr').length);

Impossible.

Anyway, you have cross-posted:

So we should continue the discussion there. I will close this old thread, which was dug up for nothing

Your statement is obviously not true, again ;)

It produces the same result but is not the same code :) I just offered another option to get what the op wants.
