定制的Bootstrap图像滑块

Question

我是Bootstrap 3 Carousel的新手，想知道在更改图像时是否有任何方法可以显示当前的滑块编号，类似于下面的示例图像：

您还可以注意到导航控件（左侧和右侧）位于当前幻灯片和幻灯片总数的旁边。

我使用this tutorial作为参考，并希望您可以帮助我解决我可以使用的其他资源。谢谢。

Answer 1

UPD。我添加了一个javascript来计算旋转木马中的幻灯片数量。

请检查结果。

$( document ).ready(function() {
  var selectIndicators = $('#myCarousel>.carousel-indicators>li');
  selectIndicators.each(function(i){
    $(this).text((i+1) + ' / ' + selectIndicators.length);
  }); 
});
