javascript - calculate the percentage between two numbers inside HTML table TD -

my complete example here in jsfiddle

i have html table few values in it. want find percentage in each tr based on td values in , have append resulted value @ end of each tr.

my jquery code

$('tr').each (function() {     var frstcol = $(this).find('.combat').text();     var secol = $(this).find('.ac_yeild').text();      var result = parseint(frstcol) * 100 / parseint(secol);     console.log(result);     $('.res').text(result); }); 

how calculate percentage first , second column , put in result column each tr?

use this:

$(this).find('.res').text(result);//this replace specific result class  

instead of

$('.res').text(result);//this replacing values of res class new value 

demo

note: getting nan value because of td contain '--' not number.
