JavaScript 游戏生成了 css 个方块，点击时角色无法跳跃

Question

我有以下游戏，css 绿色方块无法在点击时跳跃。我似乎无法发现我的错误。

如您所见，我已在 HTML 中添加了 onclick 事件，据我所知，css 动画已在样式文件中正确编码。我希望角色跳转调用 CSS 动画，最好在这个阶段避免使用 JScript 函数（或者两种选择 看看哪个更简单青年学生）

谁能发现并指出错误。

* {
  padding: 0;
  margin: 22;
}

#game {
  width: 500px;
  height: 500px;
  border: 4px solid #f74cbc
}

#character {
  width: 30px;
  height: 120px;
  background-color: green;
  position: relative;
  top: 380px;
  border-radius: 20px;
  animation: jump 500ms;
}

#enemy {
  width: 60px;
  height: 60px;
  background-color: red;
  border-radius: 10px;
  position: relative;
  top: 320px;
  left: 440px;
  animation: moveenemy 1s infinite linear;
}

@keyframes jump {
  0% {
    top: 380px;
  }
  30% {
    top: 200px;
  }
  50% {
    top: 200px;
  }
  100% {
    top: 380px;
  }
}

@keyframes moveenemy {
  0% {
    top: 440px;
  }
  50% {
    top: 58px;
  }
  100% {
    left: 0px;
    top: 320px;
  }
}

<!DOCTYPE html>
<html lang="en" onclick="jump()">
<head>
  <meta charset="UTF-8">
  <title>Battle</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <h1>TG</h1>
  <p>Avoid the red</p>

  <div id="game">
    <div id="character"></div>
    <div id="enemy"></div>
  </div>
  <script src="script.js"></script>
</body>
</html>

更新：

我知道我可以使用如下所示的 Jscript 函数，但即使那样也不起作用？

JavaScript下面试过（在script.js）

function jump(){
    if(character.classlist!="animate"){
    character.classList.add("animate");
    }
    setTimeout(function(){
        character.classList.remove("animate");
    },500);
    
}

理想情况下，如前所述，我想要尽可能简单的解决方案。是否可以指出这两个错误（提供了解决方案），以便答案中存在两种选择。推荐哪种方式？

您可以切换 CSS class 和 javascript 来执行您的跳跃动画。您不能通过 JS

直接引用 CSS 动画

// Get your character div
const character = document.getElementById('character');

// Create "jump" animation that you referenced in the "onclick".
function jump() {
  // Check if the animation is already started
  if(!character.classList.contains('jumping')){
    // Add the "jumping" class
    character.classList.add('jumping');
    // After "500 ms" remove the "jumping" class, duration must match your CSS animation length
    setTimeout(function() {
      character.classList.remove('jumping');
    }, 500);
  }
}

* {
  padding: 0;
  margin: 22;
}

#game {
  width: 500px;
  height: 500px;
  border: 4px solid #f74cbc
}

#character {
  width: 30px;
  height: 120px;
  background-color: green;
  position: relative;
  top: 380px;
  border-radius: 20px;
}

/* Moved the animation to it's own class so we can toggle it */
#character.jumping {
  animation: jump 500ms;
}

#enemy {
  width: 60px;
  height: 60px;
  background-color: red;
  border-radius: 10px;
  position: relative;
  top: 320px;
  left: 440px;
  animation: moveenemy 1s infinite linear;
}

@keyframes jump {
  0% {
    top: 380px;
  }
  30% {
    top: 200px;
  }
  50% {
    top: 200px;
  }
  100% {
    top: 380px;
  }
}

@keyframes moveenemy {
  0% {
    top: 440px;
  }
  50% {
    top: 58px;
  }
  100% {
    left: 0px;
    top: 320px;
  }
}
