This is a clean way to get rid of the commas in one line, without loops.

    var cleanNumber = $("#selector").val().split(",").join("");

Hope can help u!

var a='1,125'
a=a.replace(/\,/g,'')
a=Number(a)

Replace the regex in the replace method with /,/g which means matches the character,literally (case sensitive)

var num = '12,312,313,214,214,324.89';
var num2 = '12,312,313,214,214,324';

function replaceComma(num) {
  return num.replace(/,/g, '');
};
console.log(replaceComma(num));
console.log(replaceComma(num2));

Can't you do something like this then,

Altough the dollar sign is not included:

var num="1,000,00";
var getin=true;
var concatenate="";
for (var i=0; i<num.length; i++)
{
    if (num[i]=="," && getin){ getin=false;continue;}
    concatenate+=num[i];
}
alert(parseInt(concatenate));

It would also work for values greater then 9999 ect..

I would iterate over each element and change its' text:

var removebox = $(".remove");

removebox.each(function () {

  var oldtext = $(this).text();

  $(this).text(oldtext.replace(',', ''));

});
