将事件标记为显式非被动 [英] Mark event as explicitly NOT passive

问题描述

[违规]为滚动阻止'wheel'事件添加了非被动事件监听器。考虑将事件处理程序标记为被动以使页面更具响应性。

[Violation] Added non-passive event listener to a scroll-blocking 'wheel' event. Consider marking event handler as 'passive' to make the page more responsive.

这个警告有点让我紧张。我有一个活动，我有时需要打电话给 preventDefault（）

This warning is kinda getting on my nerves to be honest. I have an event where I sometimes need to call preventDefault()

有没有办法标记事件显然是非被动并摆脱这个警告？我知道它不会妨碍执行流程，但这是一个烦恼。我所能找到的就是如何将其标记为被动，但它是一个桌面应用程序，它不需要被动标记进行滚动优化。

Is there a way to mark the event as explicitly NOT passive and to get rid of this warning? I know it doesn't hamper execution flow, but it's an annoyance. All I can find is how to mark it passive, but it's a desktop app, which doesn't need the passive marker for scroll optimization.

我不知道是什么chrome认为当他们将其实现为默认警告时，会使开发控制台变得混乱。我觉得它就像EULAS上的同意按钮，不读，只需单击确定，cookie警告，只需单击确定...
我不想修复它，我希望忽略它，很好。

I'm not sure what chrome thought when they implemented this as default warning to clutter up the dev console. I feel like it's something like the agree button now on EULAS, don't read, just click ok, cookie warning, just click ok... I don't wish to fix it, I wish to ignore it, consiously.

推荐答案

添加侦听器时指定passive：false：

Specify passive: false when you add the listener:

el.addEventListener（'click'，someFn，{passive：false} ）;
