我正在尝试使用Bootstrap 3.2制作两个轮播指标，事实证明，相对于我的初学者JavaScript技能来说，这很困难。我尝试添加两个轮播指标列表项，但这仅对一组指标有效。如何为一个轮播使用两个轮播指示器？谢谢！
Bootstrap中的JavaScript。

最佳答案
对于我来说，我的解决方案并不完美，但也许会对您有所帮助:)
我使用的功能：
$('#carousel-example-generic').on('slide.bs.carousel', function () {
// stuffs
}
当下一个轮播项目要更改时，将调用此操作。
然后，您可以添加自己的代码，更改第二组不可更改的指标的CSS。
我的例子：
$('#carousel-example-generic').on('slide.bs.carousel', function () {
var slide_number = $('.carousel-indicators_custom')
.children('.active')
.children('.losange').attr('data-slide-to');
// here slide number need to be parseInt and you'll certainly need to add +1 value
$('.carousel-indicators_custom-mobile>li').css('color', '#333');
$('.carousel-indicators_custom-mobile').find('li[data-slide-to=' + slide_number +']').css('color', '#be1522');
$('.dynamic_puce__text').html( $('.carousel-indicators_custom-mobile').find('li[data-slide-to=' + slide_number +']').html() );
});
这有点丑陋，但这是一个开始，即使我确定他们是更好的选择。
