vue 鼠标事件控制台警告Added non-passive event listener to a scroll-blocking 'mousewheel' event. Consider marking event handler as 'passive' to make the page more responsive

如果出现这个问题，首先在鼠标滚动时间上加事件修饰符passive

@mouseleave.passive="leave"

　　，如果还没有解决，可以安装插件

npm i default-passive-events -S

　　main.js里引入

import 'default-passive-events'

至此，完美解决。亲测有效
