But its failed...

Answer 1

function cur2num(cur) {
  return parseFloat(cur.replace(/,/g,"");
}

if currency signs try /[^0-9]\.\-]/g as first argument to the replace

Answer 2

I think something as simple as

function numbers(nStr){
    return Number(nStr.replace(/[\$\,]/g,''));
}

might do the trick, though it's hard to tell without seeing your original code.
