Question

请听我说，这是我遇到的一个奇怪的错误。让我们说discountValue = 5和grandTotal = 10，discountShow将正确输出并格式化结果。但如果grandTotal为greater而不是999，discountShow将输出NaN

function discount_compute() {
  var discountValue = parseFloat($('#discount').val().replace(',', '.'));
  var discountTotal = grandTotal * (1 - (discountValue / 100));
  var discountShow = numeral(discountTotal.toFixed(2)).format('0,0.00'); 
  $('.net-total-discount').html(discountShow + " &euro;");
  }

Answer 1

你可以试试这个。

将format('0,0.00');更改为format('0,0.[00]');

jQuery计算（获取NaN，但仅当数量超过1000时）
