Can you please let me know how I can get the total and current number of the carousel slides in bootstrap like the image below?
Each slide
has a .item
class to it, you can get the total number of slides like this
var totalItems = $('.item').length;
Active slide
has a class named as active
, you can get the index of active slide
like this
var currentIndex = $('div.active').index() + 1;
You can update these values by binding the bootstrap carousel slid
event like this
$('#myCarousel').bind('slid', function() {
currentIndex = $('div.active').index() + 1;
$('.num').html(''+currentIndex+'/'+totalItems+'');
});
EXAMPLE
Update of @Khawer Zeshan's code
For Bootstrap 3.0+ use slid.bs.carousel
instead of slid
and on
instead of bind
. So the update code will be like that
var totalItems = $('.item').length;
var currentIndex = $('div.active').index() + 1;
$('#myCarousel').on('slid.bs.carousel', function() {
currentIndex = $('div.active').index() + 1;
$('.num').html(''+currentIndex+'/'+totalItems+'');
});
You can use jquery index() function to get the current index of active element inside list of item. So the code is look like this:
var currentItem = $("#carousel-1 .item.active" );
var currentIndex = $('#carousel-1 .item').index(currentItem) + 1;
Bootstrap 4 and js
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+'');
}
});

The only drawback with the below code will be that it doesn't show up till you go to next slide (triggers after each slide change).
JS/jQuery
$('#carousel-slide').on('slid.bs.carousel', function () {
var carouselData = $(this).data('bs.carousel');
var currentIndex = carouselData.getActiveIndex();
var total = carouselData.$items.length;
var text = (currentIndex + 1) + " of " + total;
$('#carousel-index').text(text);
});
HTML
<div id="carousel-index">
<!-- Number will be added through JS over here -->
</div>
var totalItemsPop = $('#Mycarousel .item').length;
$('#Mycarousel').on('slide.bs.carousel', function() {
setTimeout(function(){
currentIndexPop = $('#Mycarousel div.active').index() + 1;
$('.num').html('' + currentIndexPop + '/' + totalItemsPop + '');
}, 1000);
});
after slide event, div will be active and can not get active index, so keep your code inside set time out function
