Using JQuery to control a Bootstrap carousel and add a play and pause functionality with a Javascript function

I completed all the tasks as per the video and instructions, but encountered a problem with the button functionality. When clicking on the pause symbol, it does not change to the play symbol. However, the block is working fine.

What steps should I take to resolve this issue?

Javascript/CSS/HTML

<script>
   
    $(document).ready(function(){
    $('#carousel').carousel( { interval: 2000 } );
    $("#carouselButton").click(function(){
                if ($("#carouselButton").children("span").hasClass('fa-pause')) {
                    $("#carousel").carousel('pause');
                    $("#carouselButton").children("span").removeClass('fa-pause');
                    $("#carouselButton").children("span").addClass('fa-play');
                }
                else if ($("#carouselButton").children("span").hasClass('fa-play')){
                    $("#carousel").carousel('cycle');
                    $("#carouselButton").children("span").removeClass('fa-play');
                    $("#carouselButton").children("span").addClass('fa-pause');                    
                }
            });
    });
</script>

Answer №1

You mistakenly used the "crousalButton" Id twice. Please remove the first reference. Here:

<div class="btn group" id="carouselButton">
                <button class="btn btn-danger btn-sm" id="carouselButton">
                    <span id="carousel-button-icon" class="fa fa-pause"></span>
                </button>
            </div>

Change it to:

<div class="btn group">
                <button class="btn btn-danger btn-sm" id="carouselButton">
                    <span id="carousel-button-icon" class="fa fa-pause"></span>
                </button>
            </div>
