本文介绍了如何修改手机和标签的bootstrap轮播的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用自举滑块。

I am using a bootstrap slider.


  • 在桌面上，它有三张幻灯片，每张4个图块


  • 在选项卡上，它们必须为4每张3个瓷砖的幻灯片

  • On Tabs, they have to be 4 slides with 3 tiles each

在手机上，需要有12个不同的幻灯片

On Mobile, there needs to be 12 different slides

我正在考虑实施这一目标的最有效和最优化的方式。

I am thinking of the most effective and optimized way of implementing this.

选项1 - 创建3套不同的滑块。一次只显示一个

Option 1 - Create 3 different set of sliders. Make only one visible at a time

选项2 - 使用jquery检测屏幕宽度并以编程方式添加额外的图块作为幻灯片，隐藏额外的图块。我想这会非常复杂。

Option 2 - Detect the screen width with jquery and programmatically add extra tiles as slides, hide the extra ones. I guess this will be very complicated.

如果有更好的方法可以实现，请提供帮助。

Please help if there is a better way to implement this.

推荐答案

这是：

.carousel-inner .item.active {
  display: flex; 
}

.carousel-inner .item {
  background-color: #212121;
  color: white;
  padding: 0 15px; 
}
#desktopCarousel .carousel-inner .item > .row {
  min-height: 480px;
}
#tabletCarousel .carousel-inner .item > .row {
  min-height: 360px;
}
.carousel-inner .item > .row {
  flex-grow: 1;
  min-height: 320px;
  display: flex;
  flex-wrap: wrap;
  align-items: stretch; 
}
.carousel-inner .item > .row [class^="col-"] {
  flex-grow: 1;
  display: flex;
  flex-direction: column;
  align-items: stretch;
  justify-content: center;
  text-align: center; 
}
.carousel-inner .item > .row .row {
  flex-grow: 1;
  display: flex;
  flex-wrap: wrap;
  align-items: stretch; 
}
.carousel-inner .item > .row .row [class^="col-"] {
  display: flex;
  flex-direction: column;
  align-items: stretch;
  justify-content: center; 
}

注意你不要实际上需要CSS（它只是创建桌面滑块的布局，将每个项目中的内容（使用flexbox）+颜色居中，但我认为你已经覆盖了那些）。 CSS没有前缀，如果有帮助，你可以在小提琴中找到SCSS。 。

Note you don't actually need the CSS (it just creates the layout for desktop sliders, centers the contents in each item (with flexbox) + colors, but I assume you already got those covered). CSS is un-prefixed and, in case it helps, you'll find the SCSS in the fiddle.

此外，您可能希望为移动设备/平板电脑/台式机上的项目设置不同的 min-height 。

Also, you might want to set different min-heights for items on mobile/tablet/desktop.

除此之外，它非常干净......引导程序。没有自定义 JS ，没有自定义 CSS 。只需加价。

Other than that, it's pretty clean... bootstrap. No custom JS, no custom CSS. Just markup.

编辑：（根据评论）如果您不想要所有当更改 @media 间隔时，滑块始终在运行并且更喜欢基于调整大小监听器初始化每个滑块（我推荐 enquire.js 为此 - 缩小0.8k，在任何浏览器/设备上运行），将每个轮播的标记放在脚本中，具有不同的ID：

(as per comment) If you don't want all sliders running at all times and prefer to initialize each based on a resize listener, when changing the @media interval (I recommend enquire.js for this - 0.8k minified, runs on any browser/device), place each carousel's markup in a script, with different id's:

<script id="desktop-markup" type="text/template">
  <div id="desktopCarousel" class="carousel slide" data-ride="carousel">
    <!-- carousel markup here -->
  </div>
</script>
<script id="tablet-markup" type="text/template">
  <div id="tabletCarousel" class="carousel slide" data-ride="carousel">
    <!-- carousel markup here -->
  </div>
</script>
<script id="mobile-markup" type="text/template">
  <div id="mobileCarousel" class="carousel slide" data-ride="carousel">
    <!-- carousel markup here -->
  </div>
</script>

页面加载以及更改媒体interval，根据当前 @media 间隔获取模板的内容（即 $（'＃mobile-markup'）。html（）），将其放在指定的DOM容器中并在其上运行 .carousel（）：

On page load and on changing the media interval, get the contents of the template according to current @media interval (i.e. $('#mobile-markup').html()), place it inside the designated DOM container and run .carousel() on it:

$('.carousel-container').html(
  $('#mobile-markup').html()
).find('.carousel').carousel(options); 
// where options is optional. :) 
// see http://getbootstrap.com/javascript/#carousel-options
