解決方式
- touchmove事件或touchstart阻止默認行為
e.preventDefault();
長按好像還是不行
- 增加touchcancel事件,和touchend處理同樣的邏輯
The touchcancel event is fired when one or more touch points have been disrupted in an implementation-specific manner (for example, too many touch points are created).
當觸控點被特定的實現方式打亂時觸發 touchcancel 事件(例如, 創建了太多的觸控點)。
