Is there a way to get current slide number of an auto-slide w3 carousel?

Question

https://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_ref_js_carousel_interval&stacked=h

I have tried using the code below

function get_current_slideNumber(){
$('#myCarousel').on('slide.bs.carousel', function() {
    currentIndex = $('div.active').index() + 1;
   $('.num').html(''+currentIndex+'/'+totalItems+'');
});
}

What is the solution to this problem? Please provide a demo if possible.

Answer 1

use Bootstrap with javascript

 var totalItems = $('.item').length; var currentIndex = $('div.item.active').index() + 1; var down_index; $('.num').html(''+currentIndex+'/'+totalItems+''); $(".next").click(function(){ currentIndex_active = $('div.item.active').index() + 2; if (totalItems >= currentIndex_active) { down_index= $('div.item.active').index() + 2; $('.num').html(''+currentIndex_active+'/'+totalItems+''); } }); $(".prev").click(function(){ down_index=down_index-1; if (down_index >= 1 ) { $('.num').html(''+down_index+'/'+totalItems+''); } });
