Javascript:鼠标悬停功能不适用于 div

Question

下面是我写的代码:

window.onload = function() {
  var test = document.getElementsByClassName("experiment");
  for (var i = 0; i < test.length; i++) {
    test[i].addEventListener("mouseover", function(event) {
      console.log('its working');
      event.target.style.color = "orange";
    }, false);
  }
};

body {
  background-color: #aaa;
}

.parent-experiment {
  width: 500px;
  height: 500px;
  background-color: yellow;
  display: flex;
  justify-content: space-around;
  perspective: 500px;
}

.experiment {
  width: 250px;
  height: 250px;
  margin-top: 100px;
  background-color: blue;
  transform: rotateY(45deg);
}

<div class="parent-experiment">
  <div class="experiment"></div>
</div>

我想要的功能是当我将鼠标悬停在内部 div 元素上时，它的颜色应该变为橙色。但它根本不起作用。此外，我只想使用 javascript 完成整个功能。

如果我错了，请纠正我，但我认为您正在尝试更改背景颜色属性而不是颜色属性......就像这个例子......

另一方面，您可以仅使用带有 :hover 的 css 来实现此目的选择器..

window.onload=function(){
var test=document.getElementsByClassName("experiment");
for(var i=0;i<test.length;i++){
    test[i].addEventListener("mouseover",function(event){
        console.log('its working');
         event.target.style.backgroundColor="orange";
    },false);
    test[i].addEventListener("mouseout",function(event){
        console.log('its working');
         event.target.style.backgroundColor="blue";
    },false);
}
};

body{
background-color: #aaa;
}
.parent-experiment{
width: 500px;
height: 500px;
background-color: yellow;
display: flex;
justify-content: space-around;
perspective: 500px;
}
.experiment{
width: 250px;
height: 250px;
margin-top: 100px;
background-color: blue;
transform: rotateY(45deg);
}

    <div class="parent-experiment">
        <div class="experiment"></div>
    </div>
