在每行 5 个字段中单击时更改单个 div 的背景颜色，并在单击另一个时重置

当我陷入困境时，我在这个网站上找到了很多有用的答案，现在我发现自己迷失了方向，因为我对此很陌生，并且不知道任何javascript。

我

正在尝试向我的网站添加一个功能，该功能将包括 5 个按钮，每个按钮下方都有一个div(我有用于切换的代码，但是！！

这对你们来说可能听起来很容易，但是当我单击div 时，我该如何更改背景颜色，然后在他们单击其他div 之一时重置它，这应该适用于 5 个中的每一个。

<style type="text/css">
.btnmtb{
margin-right: 5px;
touch-action: manipulation;
cursor: pointer;
background-color: #1E2327;
padding: 20px 0px;
text-align: center;
}
.btnmtb h1 {
color: #fff;
}
.btnmtb h4 {
color: #fff;
}
.btnmtb p {
color: #fff;
font-family: 'Ubuntu', sans-serif;
font-size: 14px;
padding: 0px 20px 0px 20px;
}
</style>
<div class="disciplines">

请使用此 JavaScript 代码(更新(

var elements = document.getElementsByClassName('btnmtb');
for (var i = 0; i < elements.length; i++) {
     elements[i].addEventListener('click', function() {
        for (var j = 0; j < elements.length; j++) {
           if (elements[j].hasAttribute("style")) {
             elements[j].setAttribute('style', '');
           }
        }
        this.style.backgroundColor = "red";
     }, false);
};
