我对 javascript 编码非常陌生，并且我对构造函数/参数有足够的了解，但不足以进行故障排除。
这是我的有问题的代码部分。我试图从一系列计算中产生一个四舍五入的整数值，但我似乎无法让它工作。
如果工作正常，它将获取 20000 值，将其乘以 3 [60000]，然后除以 3250 [18.4615...]，然后向下舍入到最接近的数字 [18]。然后它将浏览器中的文本重写为 18。
$(document).ready(function() {
var moneyInSeats = $('#moneyInSeats');
var moneyInSeatsValue = moneyInSeats;
var moneyMultiplier = 3;
if (moneyInSeatsValue.text() != '') {
var seatsVisible = ((moneyInSeatsValue.text()) * moneyMultiplier);
var seatsPerSection = 3250;
var sectionsVisibleExact = seatsVisible / seatsPerSection;
var sectionsVisibleRounded = Math.floor(sectionsVisibleExact);
moneyInSeats.text(moneyMultiplier);
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id="moneyInSeats" class="hotField">20000</p>最佳答案
代码/计算没问题，您向 UI 打印了错误的值 (moneyInSeats)
moneyInSeats.text(sectionsVisibleRounded)
