Chrome浏览器中如何实现区域外鼠标事件捕捉？

const button = document.querySelector('button');
button.addEventListener('mousedown', handleMoveStart);

let startPoint;

let originalOnSelectStart = null;

function handleMoveStart(e) {
  e.stopPropagation();
  if (e.ctrlKey || [1, 2].includes(e.button)) return;
  window.getSelection().removeAllRanges();

  e.stopImmediatePropagation();
  window.addEventListener('mousemove', handleMoving);
  window.addEventListener('mouseup', handleMoveEnd); // 使用 mouseup 而不是 mousedown

  originalOnSelectStart = document.onselectstart;
  document.onselectstart = () => false;

  startPoint = { x: e.clientX, y: e.clientY }; // 使用 clientX 和 clientY
}

function handleMoving(e) {
  if (!startPoint) return;
  // 执行进度条拖动逻辑
  const deltaX = e.clientX - startPoint.x;
  // ... 更新进度条位置 ...
}

function handleMoveEnd(e) {
  window.removeEventListener('mousemove', handleMoving);
  window.removeEventListener('mouseup', handleMoveEnd);
  startPoint = undefined;
  if (document.onselectstart !== originalOnSelectStart) {
    document.onselectstart = originalOnSelectStart;
  }
}
