浮动水平手风琴

Question

我该如何解决它，下面的div打开，3个标签总是保持在同一位置？ div不应该在选项卡之间打开，但在下面。三个标签应该始终并排。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">

</div> 
 

 
<button class="menu-tabs">tab 2</button> 
 
<div class="panel"> 
 
    <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> 
 

 
<button class="menu-tabs">tab 3</button> 
 
<div id="foo" class="panel">

它会更容易通过改变你的HTML结构来解决你的问题。

下面是修改后的版本与切换基于一对按钮的ID/DIV类（我也是在CSS去掉了一些“浮码”）：

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">
