Automated JQuery image carousel

I am currently working on a basic jQuery image slider that is set to slide automatically on a timer. My goal is to make it loop seamlessly, but it seems to be getting stuck after reaching the last slide. As I am relatively new to jQuery, I might be overlooking something obvious. I have been trying to troubleshoot this issue, but haven't been able to identify what's causing the problem. Can anyone offer some guidance?

Below is the code snippet for reference:

$(document).ready(function() {

//INDEX IMAGES SLIDER
    $(function() {

//Configuration
var width = 720;
var speed = 1000;
var pause = 3000;
var current = 1;

//Cache DOM
var $slider = $('#slider');
var $slides = $slider.find('#slides');
var $slide = $slides.find('.slide');


setInterval(function() {
            //Move image to the left by the defined width and speed
    $slides.animate({'margin-left': '-='+width}, speed, function() {
            //Count the number of slides and reset to first slide after reaching the last one
current++;
if (current === $slides.length) {
current = 1;
$slides.css('margin-left', 0);
}
});
}, pause);
    });
});
#slider {
width: 720px;
height: 400px;
overflow: hidden;
}

#slider #slides {
display: block;
width: 2880px;
height: 400px;
margin: 0;
padding: 0;
}

#slider .slide {
float: left;
list-style: none;
height: 400px;
width: 720px;
}

#slider .slide img {
width: 100%;
}
<div id="slider">
  
<ul id="slides">
      
<li class="slide"><img src="images/sp_1.png"></li>
<li class="slide"><img src="images/ss_1.jpg"></li>
<li class="slide"><img src="images/sd_1.jpg"></li>
<li class="slide"><img src="images/sp_1.png"></li>
      
</ul>
  
</div>

Answer №1

There was a small error in your code. The reason $slides.length is 1 is because there is only one div with that specific id. Therefore, what you actually need to use in your if statement is $slide.length. This represents the total number of slides on the page. By adjusting your if statement as shown below, it should function correctly:

if (current === $slide.length) {
