Displaying an array of images in a Vue.js application is a common task, especially when you are working on projects that involve handling and showcasing multiple images. Vue.js, with its simplicity and flexibility, makes this process relatively straightforward. In this comprehensive guide, we will explore how to display an array of images using Vue.js and understand the code snippet provided

Displaying an Array of Images in Vue.js: A Comprehensive Guide

To get started, we have a basic Vue.js template in our HTML file. It’s important to ensure you have Vue.js included in your project, either by linking to a CDN or using a package manager like npm or yarn to install it.

  <div id="app">
    <h3> Vue Js Display Image from Array</h3>
    <div class="image-gallery">
      <div v-for="imageObject in imageObjects" :key="imageObject.src" class="image-item">
        <img :src="imageObject.src" :alt="imageObject.title">
        <p>{{ imageObject.title }}</p>
      </div>
    </div>
  </div>

In this code, we define a Vue.js app with an array of imageObjects that contains information about each image, including its title and source URL. We then use the v-for directive to loop through this array and generate a list of image items. The :key attribute is set to the image source to help Vue.js efficiently update and re-render the DOM when changes occur.

For each image item, we display the image using the img tag, binding the src attribute to the src property of the current imageObject. We also set the alt attribute to the title property to provide alternative text for the image,

Now, let’s take a look at the JavaScript part of our code:

Vue js loop through an array of images json

 <script type="module">
    const app = Vue.createApp({
      data() {
        return {
          imageObjects: [
            {
              title: 'image1.jpg',
              src: 'https://www.sarkarinaukriexams.com/images/import/sne4446407201.png',
            },
            {
              title: 'image2.jpg',
              src: 'https://www.sarkarinaukriexams.com/images/import/sne86811832.png',
            },
            {
              src: 'https://www.sarkarinaukriexams.com/images/import/sne1586776004.png',
              title: 'Image 3 Title',
            },
            // Add more objects with image URLs and titles here
          ],
        }

      },
    });
    app.mount("#app");
  </script>

In this JavaScript code, we create a Vue.js app using Vue.createApp. Inside the data function, we define the imageObjects array, where each object represents an image with a title and src property. You can easily expand this array by adding more objects with image URLs and titles.
