结合侧边栏菜单和轮播

Question

I have a sidebar menu and a bootstrap carousel and I managed to connect the carousel to the sidebar menu such that according to what item is shown in the carousel, the corresponding option in the menu is highlighted.

How can I do this the other way around such that when an option is selected from the menu, the appropriate item in the carousel is shown.

Here is my code:

 $('.carousel').on('slid.bs.carousel', function() { var carouselData = $(this).data('bs.carousel'); var currentIndex = carouselData.getItemIndex(carouselData.$element.find('.item.active')); $('.result p') .removeClass('active-p') .eq(currentIndex) .addClass('active-p'); }); 

 .active-p { background-color: #eee; }

Answer 1

Find the index with jQuery and tell the Bootstrap carousel to move to that index.

 $('.carousel').on('slid.bs.carousel', function() { var carouselData = $(this).data('bs.carousel'); var currentIndex = carouselData.getItemIndex(carouselData.$element.find('.item.active')); $('.result p') .removeClass('active-p') .eq(currentIndex) .addClass('active-p'); }); $('#sideMenu_div>p').on('click', function(e) { var currentIndex = $(this).index(); $('#myCarousel').carousel(currentIndex); }) 

 .active-p { background-color: #eee; }
