Question

如何解决，下面的div打开，3个标签始终保持在同一位置？ div不应在选项卡之间打开，而是在下方打开。三个标签应始终并排放置。这有可能吗？任何帮助将不胜感激。谢谢。

var acc = document.getElementsByClassName("menu-tabs");
var i;

for (i = 0; i < acc.length; i++) {
    acc[i].onclick = function(){
        this.classList.toggle("active");
        this.nextElementSibling.classList.toggle("show");
  }
}

button.menu-tabs {
    background-color: #fff;
    border-color: #EB282C;
    border-bottom: 1px solid #ddd;
    margin-left: 0;
    list-style: none;
    float: left;
    margin-bottom: -1px;
    position: relative;
    display: block;
}

button.menu-tabs.active, button.menu-tabs:hover {
    background-color: #ddd;
}

div.panel {
    padding: 0 18px;
    background-color: white;
    max-height: 0;
    overflow: hidden;
    transition: 0.6s ease-in-out;
    opacity: 0;
    float: none;
}

div.panel.show {
    opacity: 1;
    max-height: 500px;  
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="menu-tabs">tab 1</button>
<div class="panel">

通过更改HTML结构来解决问题会更容易。

这是一个基于对按钮ID / div类切换的修改版本（我还删除了css中的一些“浮点代码”）：

var acc = document.getElementsByClassName("menu-tabs");
var i;

for (i = 0; i < acc.length; i++) {
  acc[i].onclick = function(){
    // toggle this button, make others inactive
    var buttons = document.getElementsByClassName("menu-tabs");
    for (i = 0; i < buttons.length; i++) {
      if (buttons[i] == this) {
        buttons[i].classList.toggle("active");
      }
      else {
        buttons[i].classList.remove("active");
      }
    }
    // toggle panel associated to this, hide the others
    var panels = document.getElementsByClassName("panel");
    for (i = 0; i < panels.length; i++) {
      if (panels[i].classList.contains(this.id)) {
        panels[i].classList.toggle("show");
      }
      else {
        panels[i].classList.remove("show");
      }
    }
  }
}

button.menu-tabs {
  background-color: #fff;
  border-color: #EB282C;
  border-bottom: 1px solid #ddd;
  margin-left: 0;
  list-style: none;
  margin-bottom: -1px;
  position: relative;
  display: inline-block;
}

button.menu-tabs.active, button.menu-tabs:hover {
  background-color: #ddd;
}

div.panel {
  padding: 0 18px;
  background-color: white;
  max-height: 0;
  overflow: hidden;
  transition: 0.6s ease-in-out;
  opacity: 0;
}

div.panel.show {
  opacity: 1;
  max-height: 500px;  
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  <button class="menu-tabs" id="tab1">tab 1</button>
  <button class="menu-tabs" id="tab2">tab 2</button>
  <button class="menu-tabs" id="tab3">tab 3</button>
</div>

<div class="panel tab1">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
</div>

<div class="panel tab2">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
</div>

<div id="foo" class="panel tab3">
  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
