我为我的一门课程编写了这段代码（请记住这是初学者课程，我们刚刚开始学习 else if）。它应该写下某人的姓名、SSN、工资、时间和最后的税款。

它对我来说很好，除非 sRaw 超过 1000，然后由于某种原因它一直说 NaN 或未定义。我们还没有真正深入了解它的吸引力。我们几乎已经让算法发挥作用了。先感谢您。

您的代码中有错字

else if (fRaw > 1000)
        {
            var sExtra = fRaw - 1000;
            var fExtra = parseFloat(sExtra);
            var sfinal = (fExtra * 0.75) + (1000 * 0.85);//here, change sfinal  to sFinal
            window.alert(sFinal);
            var fFinal = parseFloat(sFinal);
            window.alert("You will recieve $" + sFinal);
            document.write("<p>Final Pay: </p>" + sFinal);
        }

花了很多时间才找到这个简单的小错字！！你应该学习的道德“错字；永远不要让它们发生”
