如何使移动设备上的轮播指示器无法点击？因此，当我在移动设备上点击它们时，幻灯片不会改变。

我正在使用最新的bootstrap。

让我们为小屏幕更改standard example的外观。

1。指标可以隐藏

将课程hidden-xs添加到<ol class="carousel-indicators">。

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.carousel-inner > .item > img {
  width: 100%;
}
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators hidden-xs">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
        <img class="img-responsive" src="http://placehold.it/600x200/c69/?text=%20" alt="Slide 1">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/69c/?text=%20" alt="Slide 2">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/9c6/?text=%20" alt="Slide 3">
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"> 
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
  
<div class="alert alert-danger hidden-xs text-center">
  Width > 767px. Make the window narrower.
</div>
<div class="alert visible-xs text-center">
  Width < 768px. Indicators are hidden.
</div>

2。指标可以关闭

添加此CSS：

@media (max-width: 767px) {
  .carousel-indicators,
  .carousel-indicators li {
    cursor: default;
    pointer-events: none;
  }
}


@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.carousel-inner > .item > img {
  width: 100%;
}

@media (max-width: 767px) {
  .carousel-indicators,
  .carousel-indicators li {
    cursor: default;
    pointer-events: none;
  }
}
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
        <img class="img-responsive" src="http://placehold.it/600x200/c69/?text=%20" alt="Slide 1">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/69c/?text=%20" alt="Slide 2">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/9c6/?text=%20" alt="Slide 3">
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"> 
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
  
<div class="alert alert-danger hidden-xs text-center">
  Width > 767px. Make the window narrower.
</div>
<div class="alert visible-xs text-center">
  Width < 768px. Indicators are turned off.

3。指标可以放在转盘下面

添加此CSS：

@media (max-width: 767px) {
  .carousel {
    margin-bottom: 7%;
  }   
  .carousel-indicators {
    bottom: auto;
    top: 105%;
  }
  .carousel-indicators li {
    border-color: #666;
  }
  .carousel-indicators .active {
    background-color: #666;
  }
}


@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.carousel-inner > .item > img {
  width: 100%;
}

@media (max-width: 767px) {
  .carousel {
    margin-bottom: 7%;
  }   
  .carousel-indicators {
    bottom: auto;
    top: 105%;
  }
  .carousel-indicators li {
    border-color: #666;
  }
  .carousel-indicators .active {
    background-color: #666;
  }
}
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
        <img class="img-responsive" src="http://placehold.it/600x200/c69/?text=%20" alt="Slide 1">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/69c/?text=%20" alt="Slide 2">
    </div>
    <div class="item">
        <img class="img-responsive" src="http://placehold.it/600x200/9c6/?text=%20" alt="Slide 3">
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next"> 
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
  
<div class="alert alert-danger hidden-xs text-center">
  Width > 767px. Make the window narrower.
</div>
<div class="alert visible-xs text-center">
  Width < 768px. Indicators are placed below the carousel.
</div>

移动设备注册touch个事件。

因此，在您的点击处理程序中，您可以区分mouse和touch个事件。

如果是touch事件，请不要做任何事情。
