這裏是我的挑戰:的JavaScript的if/else和比較/關係運算符
- Complete the
canIGet
function. This function should:
- take two arguments:
- 'item' should represent what the user wants to buy
- 'money' should represent how many dollars a user has
- return 'true' if a user can afford a given item according to the price chart below, false otherwise:
- 'MacBook Air' - $999
- 'MacBook Pro' - $1299
- 'Mac Pro' - $2499
- 'Apple Sticker' - $1
- return 'false' if the 'item' is not in the above list apple products
(而不是返回真/假我登錄到控制檯)
我會很感激的我是什麼樣的解釋做錯了。
我的代碼:
var canIGet = function(item, money){
if ((money >= 2499) && (item == "Mac Pro" || "Macbook Pro" || "Macbook Air" || "Apple sticker")){
console.log("You can afford a Mac Pro");
}
else if ((2499 > money) && (money >= 1299) && (item == "Macbook Pro" || "Macbook Air" || "Apple sticker")){
console.log("You can afford a Macbook Pro");
}
else if ((1299 > money) && (money >= 999) && (item == "Macbook Air" || "Apple sticker")){
console.log("You can afford a Macbook Air");
}
else if ((999 > money) && (money >= 1) && (item == "Apple sticker")){
console.log("You can afford a Apple sticker");
} else {
console.log("Get a job!");
}
};
canIGet("Mac Pro", 1500);

爲了檢查我們的答案,有一個摩卡測試。即使在馬克B在答案中提出的建議後,仍然存在問題。 – Tobber 2014-12-02 18:39:27
