我想在carousel-control链接上方的每张幻灯片上添加右上角的按钮。

我该怎么做？

在下面您可以看到这些按钮在carousel-control

下 

.myButton {
    position: absolute;
    top: 0;
    right: 0;
    z-index: 999; /*not working */
}

.carousel {
  height: 400px;
}

.carousel-inner {
   width: 100%; /*this must stay */
   height: 100%; /*this must stay */
   /* z-index: 1; //this make the carousel-control unclickable */
}

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">

    <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 text-center">
      <button type="button" class="myButton">Btn</button>
      Slide 1
    </div>
    <div class="item text-center">

      Slide 2
    </div>
    <div class="item text-center">
      <button type="button" class="myButton">Btn</button>
      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>

将类别为“ myButton”的按钮标签放置在类别为“ item active text-center”的div标签之前。我在以下代码中将其更改为Btn1。

 <!DOCTYPE html>
    <html>
    <head>
      <title></title>
    </head>

    <style type="text/css">
      .myButton {
        position: absolute;
        top: 0;
        right: 0;
        z-index: 999; /*not working */
    }

    .carousel {
      height: 400px;
    }

.carousel-inner {
   width: 100%; /*this must stay */
   height: 100%; /*this must stay */
   /* z-index: 1; //this make the carousel-control unclickable */
}

Z索引仅适用于彼此位于同一级别的定位元素。您应该将其设置为轮播内部课程

 .carousel-inner{
z-index:999;
}

我知道您的感觉，这也发生在我身上，直到这一刻，我还没有理想的答案。因此我提出了替代解决方案，以减小旋转木马的高度。

我知道我的替代解决方案无法完全回答您的问题，但希望它能以某种方式为您提供帮助。

u可以将内部轮播的z-index设置为高于链接，以使其位于最前面 然后，要使链接可点击，请将内部轮播设置为“ pointer-events”，将其设置为none，这将使轮播将click事件转移到其背后的元素，然后要使按钮可点击，则应将按钮的指针事件设置为auto，记住应该将每个轮播子项的指针事件属性设置为auto。

jsfiddle demo 

.myButton {
    position: absolute;
    top: 0;
    right: 0;
    z-index: 999; /*not working */
    pointer-events: auto;
}

.carousel {
    height: 400px;
}

.carousel-inner {
    pointer-events: none;
    z-index:10;
    width: 100%; /*this must stay */
    height: 100%; /*this must stay */
}
