Answer 1

添加一个<button onclick="addDifficulty()">Add Difficulty</button>

按钮

然后在JavaScript中：

function addDifficulty() {
  ais += 2
}

以下是完整代码的样子：

＆＃13;

var ais = 4

function myFunction(difficulty) {
  ais = difficulty
  document.getElementById("demo").innerHTML = ais;
}

＆＃13;

<p>Click the button to trigger a function that will change the value of ais</p>

<button onclick="myFunction(6)">Click me</button>
<button onclick="myFunction(8)">Click me</button>
<button onclick="myFunction(4)">Click me</button>

<p id="demo"></p>
