return statement

Question

我想我有missunderstod的語法，我需要一個[通用能量飲料]。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

ANSW呃只在antalAr（）的本地函數範圍內聲明。你不能在函數外部使用它。

試試這個：

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; 
     } 

編輯：哦，一個錯字以及

Answer 2

看起來像一個簡單的拼寫錯誤：

function antalAr(lan, amortering) 

應該

function antalAr(loan, amortering) 

而且，answer應該for循環之外聲明：

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