我正在尝试在类节点列表上切换javascript事件。我已经完成了下面问题的简化版本。
正在执行初始事件,但是将按钮切换回红色的第二个事件似乎不起作用? JS并链接到Codepen下面。

您只需要一个事件监听器即可实现此功能。
var $mainMenuButton = document.getElementsByClassName('desktopmenubutton');
for (h = 0; h < $mainMenuButton.length; h += 1) {
$mainMenuButton[h].addEventListener('click', function(e) {
if (e.currentTarget.style.backgroundColor == "red" || e.currentTarget.style.backgroundColor == "") {
e.currentTarget.style.backgroundColor = "black";
} else {
e.currentTarget.style.backgroundColor = "red";
}
});
}

.desktopmenubutton {
width: 150px;
height: 100px;
background-color: red;
position: absolute;
display: flex;
justify-content: center;
align-items: center;
color: white
}
.button2 {
left: 300px;
}

<div class="desktopmenubutton button1">Button 1</div>
<div class="desktopmenubutton button2">Button 2</div>
