我是 JS 和这段代码的初学者$('.brutto_amount').each(function (index, value) { let amount = $(this).text().replace(' brutto / rok', '').replace('(', ''); console.log(amount); if (discountType == 0) { let newAmount = (amount - discountValue).toFixed(2); if(newAmount < 0) newAmount = 1; $(this).html(`${newAmount} brutto / rok `); } else if (discountType == 1) { let newAmount = (amount - ((parseInt(amount) * parseInt(discountValue)) / 100)).toFixed(2); if(newAmount < 0) newAmount = 1; $(this).html(`${newAmount} brutto / rok `); }});到目前为止工作正常。如何从变量中减去 23% 的增值税newAmount并将其四舍五入到小数点后两位?
