滑动时候警告:Unable to preventDefault inside passive event listener

[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See

解决办法1:

在touch的事件监听方法上绑定第三个参数{ passive: false },
通过传递 passive 为 false 来明确告诉浏览器:事件处理程序调用 preventDefault 来阻止默认滑动行为。

elem.addEventListener(
  'touchstart',
  fn,
  { passive: false }
);

解决办法2:

* { touch-action: pan-y; }
