Question

我想我的语法错误，我需要[通用能量饮料]。它返回相同的值。

var tal1 = antalAr(1000000,1000);
document.writeln("A loan of 1000000 SEK is paid after " + 
Math.ceil(answer) + " years if the installment is 1000kr/mån.");


var tal2 = antalAr(1500000,500);
document.writeln("A loan of 1500000 SEK is paid after " + 
Math.ceil(answer) + " years if the installment is 500kr/mån.");

        function antalAr(lan, amortering)
        {
            amoyear = amortering * 12;
            for( var answer = 1; amoyear * answer <= loan; answer++){}
            return answer;
        }

Answer 1

回答仅在antalAr（）的本地函数范围内声明。你不能在函数之外使用它。

试试这个：

var tal1 = antalAr(1000000,1000);
document.writeln("A loan of 1000000 SEK is paid after " + 
Math.ceil(tal1) + " years if the installment is 1000kr/mån.");


var tal2 = antalAr(1500000,500);
document.writeln("A loan of 1500000 SEK is paid after " + 
Math.ceil(tal2) + " years if the installment is 500kr/mån.");

        function antalAr(loan, amortering)
        {
            amoyear = amortering * 12;
            for( var answer = 1; amoyear * answer <= loan; answer++){}
            return answer;
        }

编辑：哦，也是一个错字

Answer 2

看起来像一个简单的拼写错误：

function antalAr(lan, amortering)

应该是

function antalAr(loan, amortering)

此外，answer应在for循环之外声明：

function antalAr(loan, amortering) {
    var answer, amoyear = amortering * 12;
    for(answer = 1; amoyear * answer <= loan; answer++){}
    return answer;
}
