javascript - Output numbers with comma after 3 digits -

i have used jquery code

jquery.fn.digits = function(){      return this.each(function(){          jquery(this).text( $(this).text().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,") );      }) } 

for number 150000 , want out put 150,000

but outputting : 150,000.00

i don't want these .00

i find for loop easier understand regex.

function addcommas(num) {     var characters = parseint(num, 10).tostring();     var output = '';     (var offset = characters.length; offset > 0; offset -= 3) {         output = characters.slice(math.max(offset - 3, 0), offset) + (output ? ',' + output : '');     }     return output; }
