javascript - 在 Bootstrap Carousel 中单击时显示多个 div

Question

DEMO JSFiddle

我试图在单击按钮时显示多个 div。例如，我想仅在单击 Button1 时显示所有 id=div1 的 div。同样，仅在单击 Button2 时显示所有 id=div2 的 div。其他幻灯片的数量也在增加。

HTML:

<div class="container">
  <div id="myCarousel" class="carousel slide" data-ride="carousel">

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox">
      <div class="item active">
        <div class="divA">
          <div class="divAA">
            <div id="div1" class="targetDiv">
              <p>Div1 Intro: Hidden until Button1 is clicked</p>
            </div>
          </div>
          <p>
            Div1 Short to be shown by default.
            <span id="div1" class="targetDiv">Hidden span until Button1 is clicked</span>
          </p>
          <a class="showSingle" target="1">Button1</a>
          <div class="divAAA">
            <div id="div1" class="targetDiv">
              <p>
                Div1 Details: Hidden until Button1 is clicked.
              </p>
            </div>
          </div>
        </div>
      </div>

            Div2 Short
          </p>
          <a class="showSingle" target="2">Button2</a>
          <div id="div2" class="targetDiv">
            <p>
              Div2 Details: Hidden until Button2 is clicked.

Javascript:

jQuery(function(){
        jQuery('.showSingle').click(function(){
              jQuery('.targetDiv').hide();
              jQuery('#div'+jQuery(this).attr('target')).show();
        });
});

您不能对多个元素使用相同的 ID。您需要将 ID 更改为类。

您最初可以使用 CSS - display:none 隐藏它们，然后在单击按钮时可以使用类选择器而不是 id 选择器来显示它们。

这里是修改后的代码。

如果您更喜欢 fiddle :https://jsfiddle.net/ga6gmy8m/2/

jQuery(function(){
        jQuery('.showSingle').click(function(){
              jQuery('.targetDiv').hide();
             jQuery(this).hide(); jQuery('.div'+jQuery(this).attr('target')).show();
        });
});

.carousel {
  height: 200px;
  overflow-x: hidden;
  overflow-y: scroll;
}
.item {
  text-align: center;
}
.div2,.div1{
  display:none;
}
.showSingle {
  border: 1px solid #000;
  padding: 5px 10px;
  cursor: pointer;
}
