Question

我一直得到這個錯誤： - 它看起來像你的函數不返回'唉，你不符合信用卡的資格。資本主義是如此殘酷。「當收入參數是75.

有人可以告訴我我做錯了什麼嗎？歡呼:)

var creditCheck = function(income) 
if(income >= 100) 
{ 
return "You earn a lot of money! You qualify for a credit card."; 
} 
else 
{ 
return "Alas you do not qualify for a credit card. Capitalism is cruel like that."; 
} 


creditCheck(75); 
creditCheck(125); 
creditCheck(100); 

Answer 1

如何打開和關閉該功能：

var creditCheck = function (income) { 
    if (income >= 100) { 
     return "You earn a lot of money! You qualify for a credit card."; 
    } else { 
     return "Alas you do not qualify for a credit card. Capitalism is cruel like that."; 
    } 
} 

FIDDLE

Answer 2

var creditCheck = function(income) { 
    if(income >= 100) { 
     return "You earn a lot of money! You qualify for a credit card."; 
    }  else  { 
     return "Alas you do not qualify for a credit card. Capitalism is cruel like that."; 
    } 
}; 

再說了，你正在返回一個字符串，你還沒有打印到屏幕或控制檯或你什麼也看不到。
