javascript - 在 js 插槽应用程序中设置最小值和最大值

Question

我找到了这个 Jquery slots master，现在我想添加功能。

当按下按钮时，它会显示 0001 到 9999 之间的 4 位随机数。但我想将它的限制设置在 0001-9885 之间

You can see this here

它说请添加更多详细信息，我想我说得够多了......

Answer 1

function myFunction() {
    var x = document.getElementById("demo")
    x.innerHTML = Math.floor((Math.random() * 8556) + 1);
}

<!DOCTYPE html>
<html>
<body>

<p>Click the button to display a random number between 1 and 8556.</p>

<button onclick="myFunction()">Try it</button>

<p id="demo"></p>

</body>
</html>

Math.floor((Math.random() * 9885) + 1);
