Javascript chrome angular 5中的滚动问题

我是angular 5的新手，我正在用它开发一个web应用程序。该应用程序在Firefox中运行良好，但在Chrome中，我发现以下错误：

zone.js:1666[Violation]将非被动事件侦听器添加到滚动阻止“鼠标滚轮”事件中。将事件处理程序标记为“被动” 使页面更具响应性ˋ

我之所以出现此错误，是因为我在我的

angular cli.json

中包含了

smoothscroll.js

，其中包含影响chrome中鼠标滚动事件的代码：

var ischrome = /chrome/.test(navigator.userAgent.toLowerCase());
if (ischrome) {
  ssc_addEvent("mousedown", ssc_mousedown);
  ssc_addEvent("mousewheel", ssc_wheel);
  ssc_addEvent("load", ssc_init)
}

删除后，我的应用程序运行得非常好。

您是否向鼠标滚轮事件添加了任何事件侦听器？或者您是否在应用程序中的任何位置操纵滚动事件？如果是，请出示code@Und3rTow我已经尝试过这个解决方案，但对我不起作用：

document.addEventListener（“wheel”，函数（e）{e.preventDefault（）；}，{passive:true}）可能这个答案会起作用。
