sum 变量未聚合

Question

我正在尝试建立一个脚本来计算每月贷款还款额，但条件是如果贷款期限少于4个月，则不收取利息。但在第 25 行我收到错误 Monthcredit undefined，我该如何解决这个问题？结果显示在链接#msum 和#ovsum 上。蒂尔达网站建设者。

我有相同的工作脚本，但它没有提供大约4个月的条件（附在下面）-

Answer 1

monthCredit

标识符仅在任一

if (srok <= 4)

逻辑分支中声明，因此它不会在函数的其余部分尝试使用/引用它的下一个更高范围中声明。

将

monthCredit

声明移出 if 分支。

overCredit

也一样。

示例：

$( document ).ready(function() {
    var percent = 10;
    $(".tn-atom__form").on('input', ".t-range", function() {
        setTimeout(function(){
             let summa = $('input[name="summa"]').next('.t-range__value-txt').html();
             let srok = $('input[name="srok"]').next('.t-range__value-txt').html();
             let monthPercent = percent/100/12;
             //Возведение в степень
             let degree = Math.pow( 1+monthPercent , -srok);

             let monthCredit = 0;
             let overCredit = 0;

             if (srok <= 4) {
                 monthCredit = summa/srok;
                 overCredit =0
             } else {
                 monthCredit = summa*(monthPercent/(1-degree));
                 overCredit = monthCredit*srok-summa
             }
             //Выводим итоги в текст
             monthCredit = monthCredit.toFixed();
             overCredit = overCredit.toFixed();
             monthCredit = monthCredit.replace(/(\d)(?=(\d\d\d)+([^\d]|$))/g, '$1 ');
             overCredit = overCredit.replace(/(\d)(?=(\d\d\d)+([^\d]|$))/g, '$1 ');     
             $('a[href="#msum"]').html(monthCredit+' руб.');
             $('a[href="#ovsum"]').html(overCredit+' руб.');
        }, 100);
    });
});
</script>
