JavaScript Event Handling: Exercise-5 with Solution

Image Slideshow Navigation

Write a JavaScript program to create a slideshow that changes the displayed image when a next or previous button is clicked.

Sample Solution:

HTML and JavaScript Code:

<!DOCTYPE html>
<html>
<head>
  <style>
    .slideshow {
      display: flex;
      justify-content: center;
      align-items: center;
      height: 300px;
    }

    .slideshow img {
      width: 300px;
      height: 300px;
    }
  </style>
</head>
<body>
  <div class="slideshow">
    <button id="previousBtn">Previous</button>
    <img id="image" src="image1.jpg">
    <button id="nextBtn">Next</button>
  </div>

  <script>
    const images = ['image1.jpg', 'image2.jpg', 'image3.jpg'];
    let currentIndex = 0;

    const previousBtn = document.getElementById('previousBtn');
    const nextBtn = document.getElementById('nextBtn');
    const image = document.getElementById('image');

    previousBtn.addEventListener('click', () => {
      currentIndex = (currentIndex - 1 + images.length) % images.length;
      image.src = images[currentIndex];
    });

    nextBtn.addEventListener('click', () => {
      currentIndex = (currentIndex + 1) % images.length;
      image.src = images[currentIndex];
    });
  </script>
</body>
</html>
