After carefully reviewing the documentation, it seems there isn't a specific event to detect when the carousel is paused. Is there a workaround for detecting when the bootstrap carousel is paused?
The carousel can be paused using various methods, and I am looking to display a paused icon whenever it is in a paused state.
This is not a straightforward answer, but rather a suggestion on how to handle the absence of a specific pause event in carousel functionalities. Instead of a direct pause event, you can make use of the slide.bs.carousel and slid.bs.carousel events. For instance, when a slide occurs, you can initiate a pause and trigger a custom event called pause-detect.
So, what's the benefit of this approach? By identifying the events that lead to a pause (like 'mouseenter', for example), you can monitor those events and then trigger the custom event accordingly.
Update: As an illustration, I have included the default pause event of mouseenter as an example, which has been remarked out within the slid event where it triggers a pause.
$('#carouselExampleIndicators').carousel();
$('#carouselExampleIndicators')
.on('slid.bs.carousel', function(event) {
// do something…
let mycar = $(this);
// mycar.carousel("pause");
let currentSlide = $(event.relatedTarget);
/* mycar.trigger('pause-detect', [{
slide: currentSlide
}]);
*/
}).on('mouseenter', function(event) {
let mycar = $(this);
let currentSlide = mycar.find('.active');
mycar.trigger('pause-detect', [{
slide: currentSlide
}]);
}).on('pause-detect', function(event, mycarousel) {
// let mycar = $(this);
// let elemEvents = $._data(mycar.get(0), "events");
// console.log(elemEvents);
console.log("paused:", event.target); // carousel element
console.log("slide:", mycarousel.slide.get(0), mycarousel.slide.find('img').attr('alt'));
});.carousel-item {
height: 200px;
border: solid lime 1px;
background-color: #AADDFF;
color: blue;
