为什么我的Javascript函数被跳过了？

Question

我只是想制作这个简单的脚本来询问用户他们想要订购什么，但该功能正在被完全跳过。

var foodOrder = function (food) {
    var ask = prompt("What food would you like to order?");

    alert("Okay, "+ask+" coming right up.");

};

var more = prompt("Would you like anything else?");

if (more === "Yes") {
    foodOrder();
}
else
{
    alert("Goodbye");
}

有人看到我做错了吗？

Answer 1

我认为您输入的是'yes'而不是'Yes'，这就是条件为false的原因。 与此相比：

if (more.toLowerCase() === 'yes') { /* ... */ }

Answer 2

试试这个 -

var foodOrder = function (food)
{
    var ask = prompt("What food would you like to order?");
    alert("Okay, "+ask+" coming right up.");
};

var more = prompt("Would you like anything else?");

if (more.toLowerCase() === "yes")
{
    foodOrder();
}
else
{
    alert("Goodbye");
}
