How to fetch the value of tabular form item in javascript

Question

Hello all
I want to do some calculations on the value entered by the user in the textfield of a tabular form, how can I fetch the value of tabular form item in the javascript?
I am using normal tabular form, not using apex_item tabular form.
I can pass the current textfield value to the function using "this" as a parameter, but how can I fetch the value of other rows of that same column?
Thanks

Hi Alistair
jQuery is still not working, but I got it done through some other means, this is the code:
function total(pThis){
var l_Row = html_CascadeUpTill(pThis,'TR');
var l_Table = l_Row.parentNode;
var l_Row_next = l_Row;
var n_rows = l_Table.rows;
var lInputs;
var v1;
var sum = 0.0;
var temp;
var i = 0;
var j = 0;
//alert(n_rows.length);
while(j < (n_rows.length - 1))
temp = 0;
if(l_Row_next != null){
lInputs = html_Return_Form_Items(l_Row_next,'TEXT');
v1 = lInputs[0].value;
//alert(v1);
sum = parseFloat(sum) + parseFloat(v1);
l_Row_next = l_Row_next.nextSibling;
temp = 1;
if(temp == 0){
l_Row_next = l_Table.getElementsByTagName('TR')[1];
lInputs = html_Return_Form_Items(l_Row_next,'TEXT');
v1 = lInputs[0].value;
sum = parseFloat(sum) + parseFloat(v1);
l_Row_next = l_Row_next.nextSibling;
j= j+1;
$x('P78_TOTAL').value= parseFloat(sum);
I am calling this function onblur event of the textfield.
Still I am having one problem, I want to perform this calculation on load of the page also, how can I do that? because while calling onblur of the textfield I can pass that textfield to this function but on onLoad how I will pass the textfield to call this function so that I will be able to get the textfield value in the function?
there may be some rows already existing, so I want the total of the existing rows to be displayed in my P78_TOTAL textfield that is why I need to do this calculation on onLoad of the page.
Thanks
