我有3个锚标签按钮和6个div，我想为每个按钮分配2个div，当单击时，两个指定的div都会相应地显示/隐藏。

我能够使用下面的代码隐藏/显示前3个div，但是对于接下来的3个div(图像部分)，我的代码无法工作。

html:

//button section
 <div class="row">
   <div class="col-4 col-sm-2 col-lg-2">
      <div class="mx-2"><a id="me" class="trans-btn selected" onclick="show('id1');">Widget</a></div>
      <div class="mx-2"><a id="me" class="trans-btn" onclick="show('id2');">Widget</a></div>
      <div class="mx-2"><a id="me" class="trans-btn" onclick="show('id3');">Widget</a></div>
   </div>
//1st 3 divs
   <div class="col-8 col-sm-5 col-lg-5">
      <div class="mx-2" id="id1">
         <h3>Tabs with soft transitioning effect.</h3>

      <div class="mx-2" id="id3" style="display:none;"><img class="img-fluid" src="assets/images/shadow-img.png"/></div>
   </div>
</div>

js:

function show(elementId) { 
    document.getElementById("id1").style.display="none";
    document.getElementById("id2").style.display="none";
    document.getElementById("id3").style.display="none";
    document.getElementById(elementId).style.display="block";
}

当单击指定的按钮时，是否有其他方法显示/隐藏两个div？

function

display

javascript

css

您正在使用相同的id两次。这是不允许的。我已经修改了你的HTML来纠正这个问题。我希望这能帮到你。

function show(elementId) { 
   let divs = Array.from(document.querySelectorAll("[id ^= 'did']"));
   let imgs = Array.from(document.querySelectorAll("[id ^= 'iid']"));
   divs.forEach(d=>{d.style.display="none"})
   imgs.forEach(i=>{i.style.display="none"})
   document.getElementById("d"+elementId).style.display="block";
   document.getElementById("i"+elementId).style.display="block";
    }

<div class="row">
   <div class="col-4 col-sm-2 col-lg-2">
      <div class="mx-2"><a id="me" class="trans-btn selected" onclick="show('id1');">Widget1</a></div>
      <div class="mx-2"><a id="me" class="trans-btn" onclick="show('id2');">Widget2</a></div>
      <div class="mx-2"><a id="me" class="trans-btn" onclick="show('id3');">Widget3</a></div>

您应该考虑将jQuery包含到项目中。jQuery已经提供了这个功能。

在html标记中添加以下代码：

<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>

然后，您将能够在本例中使用以下函数--切换函数，您可以在其中切换指定元素的类：

$( "#id1, #id2, #id3" ).toggle(
  function() {
    $( this ).addClass( "show" );
  }, function() {
    $( this ).removeClass( "hide" );
  }
);

请参阅jquery文档中的切换并单击events：

https://api.jquery.com/toggle-event/

https://api.jquery.com/click/

并泛化了jQuery文档以找到其他类似的功能：

https://api.jquery.com

如果将引导程序添加到项目中，则显示和隐藏类将已经包含在项目中。并提供你想要的功能。

我希望这能帮到你。

可以使用.querySelectorAll方法并隐藏所有这些元素。

function show(elementId) { 
    [].slice.call(document.querySelectorAll(".myBlock"),0).map(e=>e.style.display="none")
    document.getElementById(elementId).style.display="block";
}

//button section
 <div class="row">
   <div class="col-4 col-sm-2 col-lg-2">
      <div class="mx-2"><a id="me1" class="trans-btn selected" onclick="show('id1');">Widget</a></div>
      <div class="mx-2"><a id="me2" class="trans-btn" onclick="show('id2');">Widget</a></div>
      <div class="mx-2"><a id="me3" class="trans-btn" onclick="show('id3');">Widget</a></div>
   </div>
