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
