Chrome TouchEvent passive 参数介绍
· 15 min read
在 Chrome 浏览器中使用以下代码:
document.body.addEventListener("touchmove", (e) => {
console.log(e);
})
会在控制台看到一个警告信息:
[Violation] Added non-passive event listener to a scroll-blocking 'touchmove' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952
