JS 初学者寻求关于非常短的函数的帮助

Question

我不明白为什么这段代码会在代码后面生成错误，我希望有人能帮助指出我的语法错误：

var userprompt = function() {
    var num = prompt("Enter a number")
    if (num % 7 == 0) {
        console.log("Lucky, your number is divisiable by 7!");
    };
    else if (num % 2 == 0) {
        console.log("Your number is an even number!");
    };
    else {
        console.log("That number is not awesome.");
    };
};

错误（由 Chrome JS 控制台产生）

SyntaxError: Unexpected token else
message: "Unexpected token else"
stack: (...)
get stack: function () { [native code] }
set stack: function () { [native code] }
__proto__: Error

**根据 Agrum 的建议编辑了代码，当在 Chrome JS Console 中运行时，唯一发生的事情就是弹出警报消息。

var userprompt = function() {
var num = prompt("Enter a number");
if (num % 7 == 0) {
console.log("Lucky, your number is divisiable by 7!")
}
else if (num % 2 == 0) {
console.log("Your number is an even number!")
}
else {
console.log("That number is not awesome.")
}
};

alert("This is a test");

Answer 1

这些 if 的结束括号后不需要分号。

if(true) { console.log("something"); }

不是

if(true) { console.log("something"); };

Answer 2

var userprompt = function() {
 var num = prompt("Enter a number");
 if (num % 7 == 0) {
  console.log("Lucky, your number is divisiable by 7!");
 }
 else if (num % 2 == 0) {
  console.log("Your number is an even number!");
 }
 else {
  console.log("That number is not awesome.");
 }
};

编辑：每条指令后还缺少一个分号。
