How to Create a Left Sliding Image Slider with jQuery?

Estimated read time 3 min read

To create a left sliding image slider with jQuery, you can follow these steps:

  1. Create a container element in your HTML code that will hold the slider images. Here’s an example:
<div id="slider">
  <img src="image1.jpg" alt="">
  <img src="image2.jpg" alt="">
  <img src="image3.jpg" alt="">
</div>
  1. Add some CSS code to position the slider container and set its width and height. Here’s an example:
#slider {
  position: relative;
  width: 500px;
  height: 200px;
  overflow: hidden;
}

#slider img {
  position: absolute;
  left: 0;
  top: 0;
  width: 500px;
  height: 200px;
}

This code will create a slider container with a fixed width and height, and set its overflow to hidden so that anything outside of it will be hidden. The images inside the container will be positioned absolutely and anchored to the top-left corner, with the same width and height as the container.

  1. Add some JavaScript code that will animate the slider images when the user clicks a button or triggers an event. Here’s an example:
var currentPosition = 0;
var sliderWidth = $('#slider').width();
var slideCount = $('#slider img').length;
var slideInterval = 3000;

function moveSlider() {
  if (currentPosition == slideCount - 1) {
    currentPosition = 0;
  } else {
    currentPosition++;
  }
  $('#slider').animate({ left: -currentPosition * sliderWidth }, 1000);
}

var sliderInterval = setInterval(moveSlider, slideInterval);

$('#slider').hover(function() {
  clearInterval(sliderInterval);
}, function() {
  sliderInterval = setInterval(moveSlider, slideInterval);
});

This code will initialize some variables that keep track of the current position of the slider, the width of the slider container, the number of images in the slider, and the interval between slides. It also defines a function that moves the slider to the next image by animating the left position of the slider container. Finally, it sets up an interval that calls the moveSlider function every slideInterval milliseconds, and adds a hover event listener to the slider that stops and starts the interval when the user hovers over or out of the slider.

  1. Make sure to include jQuery in your HTML code before the script that you just created. Here’s an example:
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script>
  // Add the JavaScript code here
</script>

That’s it! Now, the slider will automatically slide left to reveal the next image every few seconds, and the user can hover over or out of the slider to pause or resume the animation. You can customize the slider by changing the values in the JavaScript code, such as the interval between slides and the animation duration.
