chrome 区域外事件捕捉
在 chrome 浏览器中,不再支持 setcapture() 方法,而 window.captureevents() 也已弃用。因此,我们需要寻找其他方法来实现当进度条拖动到进度条区域外时,仍然触发鼠标移动事件。
解决方案:
以下代码提供了一种解决方案,它使用以下步骤:
代码示例:
const button = document.querySelector('button'); button?.addEventListener('mousedown', handleMoveStart); let startPoint: { x: number; y: number } | undefined; let originalOnSelectStart: Document['onselectstart'] = null; function handleMoveStart(e: MouseEvent) { e.stopPropagation(); if (e.ctrlKey || [1, 2].includes(e.button)) return; window.getSelection()?.removeAllRanges(); e.stopImmediatePropagation(); window.addEventListener('mousemove', handleMoving); window.addEventListener('mousedown', handleMoveEnd); originalOnSelectStart = document.onselectstart; document.onselectstart = () => false; startPoint = { x: e.x, y: e.y }; } function handleMoving(e: MouseEvent) { if (!startPoint) return; // DO Something } function handleMoveEnd(e: MouseEvent) { window.removeEventListener('mousemove', handleMoving); window.removeEventListener('mousedown', handleMoveEnd); startPoint = undefined; if (document.onselectstart !== originalOnSelectStart) { document.onselectstart = originalOnSelectStart; } }
