如何知道滚动事件是使用鼠标滚轮引发的,还是在滚动条上操纵光标引发的?

window.addEventListener("scroll",(scroll)=>{
 console.log(scroll)
})

html,body{
  height:100%;
  width:100%;
  padding:0px;
  margin:0px;
}

*{
 box-sizing:border-box !important;
}

#final{
  border:1px solid red;
}

.height500vh{
 height:500vh;
}

<div class="height500vh"></div>
<div id="final">final</div>
