  }

  function addNumbers() {

    var val1 = parseInt(document.getElementById("value1").value);
    val val2 = parseInt(document.getElementByID("value").value);

解决方案

有你想要的代码运行。如果要在 html 页面中输出结果，只需使用要更改的 id 的 innerHTML 方法即可。

<!DOCTYPE html>
<html>
<body>

<p>Click the button to demonstrate the prompt box.</p>

<button onclick="myFunction()">Click me</button>

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

<script>
function myFunction() {
    var person = prompt("Please enter your name");
    var firstN = prompt("Please enter a number between 1 and 100");
    var secondN = prompt("Please enter a number between 10 and 20");
    document.getElementById("demo").innerHTML = "Dear "+person+" the first number you entered was "+firstN+" the second was "+secondN+". If we multiply these two number we get "+(firstN*secondN);
}
</script>

</body>
</html>
