在 html 按钮中嵌入脚本

Question

So, I'm a beginner programmer and figured I could do something short and fun.所以，我是一个初学者程序员，我想我可以做一些简短而有趣的事情。 I made a short program in like 5 minutes, but I ran into a problem where I can't figure out, how to make a button that runs a said script when pressed (eg makes an alert with a random number in it) Here's my code我在 5 分钟内编写了一个简短的程序，但我遇到了一个我无法弄清楚的问题，如何制作一个在按下时运行所述脚本的按钮（例如，发出带有随机数的警报）这是我的代码

<!DOCTYPE html>
<html>
    <Head>
        <h2>
        Random number Generator
        </h2>
    </Head>
    <body>
         <script src ="Script.js"></script>
        <button type="button" onclick="alert(randomNum)"> Generate! </button>
    </body>
</html>

and the script part here和这里的脚本部分

    let newNumber = Math.random()
    let oneToHundred = newNumber * 1000
    let result = Math.floor(oneToHundred)
    return result
};
alert(randomNum) ```

I just can't figure out how to make the button search for a script and run it when pressed. I tried to embed the script search to the onclick part, but i got a syntax error.
Any help appreciated
