and want utilize value of attribute "data_price" calculate sum in link : http://jsfiddle.net/qmtnz/77/

i want utilize attribute "data_price" in calculation , not .

please help, i'm still beginner in jquery :)

for cost cells, should utilize format:

<td data-price="1375.5">&euro;1,375.50</td>

i.e. hyphen, not underscore

you can use:

$('td').data('price')

to access value - see http://api.jquery.com/data

e.g.

var sum = 0; $('.sum').each(function() { var q = parsefloat($(this).find('.qty').val()); var p = parsefloat($(this).find('td').eq(2).data('price')); sum += q * p; }); $('#total').text(sum);

working demo @ http://jsfiddle.net/alnitak/gzyhn/
