How to Get total and Current Slide Number of Carousel

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+'');
});

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+'');
});
