德国货币的LocalString方法?

用户名
var n = (1223578.00).toLocaleString('de-DE');

应为->“ 1.223.578,00”,但输出为:1.223.578(缺少小数位)

怎么了 ?

<script type="text/javascript">var amount= '{{currency1}}';</script>

这是来自SQL的填充表格,currency1 = 1223578.00

如何使用这个占位符?

将minimumFractionDigits属性设置为所需的位数。

var n = (1223578.00).toLocaleString('de-DE',{ minimumFractionDigits: 2 });

产生:1.223.578,00

上述功能可能不适用于所有浏览器。为了确保在所有浏览器上的结果相同,您可以手动创建字符串,如下所示:

修改自:https : //stackoverflow.com/a/16157942/4347337

function DelocaleString(x, sep, grp, dec) {
  //add decimals
  var y = x.toFixed(dec);
  //strip decimals
  var x_integer = y.split('.')[0];
  var x_fraction = y.split('.')[1];
  var x_fractionString = "";
  if (dec > 0) {
    x_fractionString = ',' + x_fraction;
  }
  var sx = ('' + x_integer).split('.'),
    s = '',
    i, j;
  sep || (sep = ' '); // default seperator
  grp || grp === 0 || (grp = 3); // default grouping
  i = sx[0].length;
  while (i > grp) {
    j = i - grp;
    s = sep + sx[0].slice(j, i) + s;
    i = j;
  }
  s = sx[0].slice(0, i) + s;
  sx[0] = s;
  return sx.join('.') + x_fractionString
}

$().ready(function() {
  $('#convertBtn').click(function() {
    ConvertNumber();
  });
});

function ConvertNumber() {
  var input = $('#in').val();
  if ($.isNumeric(input)) {
    $('#out').val(DelocaleString(+input, '.', 3, 2));
  } else {
    $('#out').val('Input is not a number!');
  }
}

function DelocaleString(x, sep, grp, dec) {
  //add decimals
  var y = x.toFixed(dec);
  //strip decimals
  var x_integer = y.split('.')[0];
  var x_fraction = y.split('.')[1];
  var x_fractionString = "";
  if (dec > 0) {
    x_fractionString = ',' + x_fraction;
  }
  var sx = ('' + x_integer).split('.'),
    s = '',
    i, j;
  sep || (sep = ' '); // default seperator
  grp || grp === 0 || (grp = 3); // default grouping
  i = sx[0].length;
  while (i > grp) {
    j = i - grp;
    s = sep + sx[0].slice(j, i) + s;
    i = j;
  }
  s = sx[0].slice(0, i) + s;
  sx[0] = s;
  return sx.join('.') + x_fractionString
}
