js原生元素拖拽案例

下面是一个简单的使用原生 JavaScript 实现元素拖拽的代码示例：

<!DOCTYPE html>
<html>
<head>
  <style>
    .draggable {
      width: 100px;
      height: 100px;
      background-color: red;
      position: absolute;
      cursor: move;
    }
  </style>
</head>
<body>
  <div class="draggable"></div>

  <script>
    window.onload = function() {
      var draggable = document.querySelector('.draggable');
      var isDragging = false;
      var offsetX = 0;
      var offsetY = 0;

      draggable.addEventListener('mousedown', function(event) {
        isDragging = true;
        offsetX = event.clientX - draggable.offsetLeft;
        offsetY = event.clientY - draggable.offsetTop;
      });

      document.addEventListener('mousemove', function(event) {
        if (isDragging) {
          draggable.style.left =
