js圆形走动数字时钟代码

以下是一个使用 JavaScript 实现的圆形走动数字时钟的示例代码：

    #clock {
      width: 200px;
      height: 200px;
      border-radius: 50%;

      display: flex;

      align-items: center;

    }
  </style>
</head>

<body>
  <div id="clock"></div>

  <script>
    function updateClock() {
      const now = new Date();
      const hours = now.getHours().toString().padStart(2, '0');
      const minutes = now.getMinutes().toString().padStart(2, '0');
      const seconds = now.getSeconds().toString().padStart(2, '0');
      const timeString = `${hours}:${minutes}:${seconds}`;

      const clockElement = document.getElementById('clock');
      clockElement.textContent = timeString;

      // 计算角度并旋转数字
      const angle = (new Date().getSeconds() / 60) * 360;
      clockElement.style.transform = `rotate(${angle}deg)`;
    }

    setInterval(updateClock, 1000);
    updateClock(); // 初始化时钟
  </script>
</body>
