Bootstrap 3多列响应式走马灯

Question

我一直在尝试使用bootstrap轮播组件，让它能够响应式地每个滑块显示4列。在响应式方面已经很完美了，然而当最后一个滑块滑动时，轮播没有回到第一个滑块，而是消失了。有人能够确定问题所在吗？

HTML

<div id="carousel-example-generic" class="carousel slide">
<!-- 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"> 
    <!-- Slide -->
    <div class="item active">
        <div class="row">
            <div class="col-sm-3 col-xs-6"> <img src="http://placehold.it/260x180" alt=""/>
                <div class="carousel-caption">This is a caption</div>
            </div>
            <div class="col-sm-3 col-xs-6"> <img src="http://placehold.it/260x180" alt=""/>
                <div class="carousel-caption">This is a caption</div>

    <!-- Controls --> 
    <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev"> <span class="icon-prev"></span> </a> <a class="right carousel-control" href="#carousel-example-generic" data-slide="next"> <span class="icon-next"></span> </a>
</div>

JS

$('#carousel-example-generic').carousel();

CSS

.carousel.slide img {
    width:100%;
    height:auto;
}

jsFiddle

[更新]这是一个更新的jsFiddle，感谢Adrift！

[更新2]http://jsfiddle.net/S2rnm/795/此版本能够根据设备尺寸自适应地显示包含4、2或1个列的不同走马灯。它需要3个带有不同visible-x类的走马灯。

问题在于你把轮播控制器放在了.carousel-inner内部，你只需要把它们放在这个类的外面即可：

  </div> <!-- Close the .carousel-inner class before the controls -->
    <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
      <span class="icon-prev"></span>
    </a>
    <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
      <span class="icon-next"></span>
    </a>

我已经更新了我的问题，包括Adrift修复的代码和另一个版本，显示不同设备尺寸下的列数。需要3个不同的走马灯... - gpcola
