Javascript - Change image src jquery animation

To change the src attribute of an image using jQuery with animation, you can use the .fadeOut() and .fadeIn() methods to smoothly transition between images. Here's an example:

HTML:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Image Animation</title> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> </head> <body> <img id="myImage" src="image1.jpg" alt="Image"> <button id="changeImage">Change Image</button> <script src="script.js"></script> </body> </html>

JavaScript (script.js):

$(document).ready(function(){ // Image sources var images = ["image1.jpg", "image2.jpg", "image3.jpg"]; var currentIndex = 0; // Function to change image with animation function changeImage() { // Fade out the current image $('#myImage').fadeOut(500, function() { // Increment currentIndex and wrap around if necessary currentIndex = (currentIndex + 1) % images.length; // Set the new image src $(this).attr('src', images[currentIndex]); // Fade in the new image $(this).fadeIn(500); }); } // Button click event to change image $('#changeImage').click(changeImage); });

In this example:

  • We have an <img> element with the id myImage initially showing the first image (image1.jpg).
  • There's a button with the id changeImage to trigger the image change.
  • In JavaScript, we define an array images containing the image sources.
  • We keep track of the current image index using the currentIndex variable.
  • The changeImage() function fades out the current image using .fadeOut() with a duration of 500 milliseconds.
  • Once the fade out animation is complete, the function increments the currentIndex, sets the src attribute of the image to the next image source in the array, and fades in the new image using .fadeIn() with a duration of 500 milliseconds.
  • When the button is clicked, it triggers the changeImage() function to change the image with animation.

Examples

  1. "JavaScript change image source with fade effect" Description: This query suggests a desire to change an image source using JavaScript with a smooth transition effect.

    // JavaScript code function changeImageWithFade() { var img = document.getElementById('myImage'); var newImgSrc = 'new_image.jpg'; var fadeInDuration = 1000; // milliseconds // Fade out current image img.style.opacity = 0; // Change image source after fade out setTimeout(function() { img.src = newImgSrc; // Fade in new image img.style.transition = 'opacity ' + fadeInDuration / 1000 + 's'; img.style.opacity = 1; }, fadeInDuration); } 
    <!-- HTML code --> <img id="myImage" src="old_image.jpg" alt="Old Image"> <button onclick="changeImageWithFade()">Change Image</button>

  2. "JavaScript replace image smoothly jQuery" Description: This query indicates a preference for using jQuery to smoothly replace an image with another one.

    // JavaScript with jQuery code function changeImageWithFade() { var newImgSrc = 'new_image.jpg'; var fadeInDuration = 1000; // milliseconds $('#myImage').fadeOut(fadeInDuration, function() { $(this).attr('src', newImgSrc).fadeIn(fadeInDuration); }); } 
    <!-- HTML code --> <img id="myImage" src="old_image.jpg" alt="Old Image"> <button onclick="changeImageWithFade()">Change Image</button>

  3. "JavaScript switch image with animation" Description: This query seeks a way to switch images with an animated effect using JavaScript.

    // JavaScript code function switchImageWithAnimation() { var img = document.getElementById('myImage'); var newImgSrc = 'new_image.jpg'; // Apply animation effect $(img).fadeOut(500, function() { img.src = newImgSrc; $(this).fadeIn(500); }); } 
    <!-- HTML code --> <img id="myImage" src="old_image.jpg" alt="Old Image"> <button onclick="switchImageWithAnimation()">Switch Image</button>

  4. "JavaScript image change smooth transition vanilla" Description: This query expresses a desire for a vanilla JavaScript solution to smoothly transition between images.

    // JavaScript code function changeImageSmoothTransition() { var img = document.getElementById('myImage'); var newImgSrc = 'new_image.jpg'; var fadeStep = 0.05; // Step for opacity change var fadeInterval = 50; // Interval for opacity change (milliseconds) var fadeOutInterval = setInterval(function() { if (img.style.opacity > 0) { img.style.opacity -= fadeStep; } else { clearInterval(fadeOutInterval); img.src = newImgSrc; var fadeInInterval = setInterval(function() { if (img.style.opacity < 1) { img.style.opacity = parseFloat(img.style.opacity) + fadeStep; } else { clearInterval(fadeInInterval); } }, fadeInterval); } }, fadeInterval); } 
    <!-- HTML code --> <img id="myImage" src="old_image.jpg" alt="Old Image"> <button onclick="changeImageSmoothTransition()">Change Image</button>

  5. "JavaScript animate image change without jQuery" Description: This query seeks a JavaScript solution for animating image changes without relying on jQuery.

    // JavaScript code function animateImageChange() { var img = document.getElementById('myImage'); var newImgSrc = 'new_image.jpg'; var animationDuration = 1000; // milliseconds var framesPerSecond = 60; var frameDuration = 1000 / framesPerSecond; var frameOpacityChange = 1 / (animationDuration / frameDuration); var currentOpacity = 1; var animationInterval = setInterval(function() { currentOpacity -= frameOpacityChange; img.style.opacity = currentOpacity; if (currentOpacity <= 0) { clearInterval(animationInterval); img.src = newImgSrc; currentOpacity = 0; var fadeInInterval = setInterval(function() { currentOpacity += frameOpacityChange; img.style.opacity = currentOpacity; if (currentOpacity >= 1) { clearInterval(fadeInInterval); currentOpacity = 1; } }, frameDuration); } }, frameDuration); } 
    <!-- HTML code --> <img id="myImage" src="old_image.jpg" alt="Old Image"> <button onclick="animateImageChange()">Change Image</button>
