JS小数位数不足二位，自动补零0

function returnFloat(value){
  var value = Math.round(parseFloat(value) * 100) / 100;
  var s = value.toString().split(".");
  if(s.length== 1){
    value = value.toString() + ".00";
    return value;
  }
  if (s.length > 1) {
    if (s[1].length < 2) {
      value = value.toString() + "0";
    }
    return value;
  }
}
