js Realizes Thousand Character Conversion


function fmoney(s, n)

{
 n = n > 0 && n <= 20 ? n : 2;
 s = parseFloat((s + '').replace(/[^\d\.-]/g, '')).toFixed(n) + '';
 var l = s.split('.') [0].split('').reverse(),
   r = s.split('.') [1];
 var t = '';
 for (var i = 0; i < l.length; i++)
 {
   t += l[i] + ((i + 1) % 3 == 0 && (i + 1) != l.length ? ',' : '');
 }
 return t.split('').reverse().join('') + '.' + r;

 }

Use var amount = fmoney (123456.78, 2);

console.log(amount);

Result: 123,456.78
