How to implement image preview function in Vue

In today’s web design, image carousel is a very common effect. When using the Vue framework to develop web pages, we can implement this function through Vue plug-ins. This article will provide specific code examples to introduce how to implement the image preview function in Vue.

1. Introducing plug-ins

We can use the Vue plug-in vue-awesome-swiper to implement the image carousel function. Vue-awesome-swiper is a carousel component that supports infinite loop carousels, dynamic addition and deletion of carousel items, responsiveness, and page turning animations.

Use npm to install vue-awesome-swiper:

npm install vue-awesome-swiper --save

Reference swiper and its style in main.js:

import Vue from 'vue'
import App from './App.vue'
import Swiper from 'vue-awesome-swiper'
// import Swiper styles
import 'swiper/dist/css/swiper.css'
Vue.use(Swiper)

new Vue({
  el: '#app',
  render: h => h(App),
})

2. Use the Vue-awesome-swiper component

The following code demonstrates how to use the Vue-awesome-swiper component:

3. Add image preview function

In the above example, when the user clicks on the image , we call a method to preview the image. We use a Vue plug-in called vue-js-modal here to achieve this function.

We can use npm to install the vue-js-modal plug-in:

npm install --save vue-js-modal

Introduce the module in main.js and declare:

import Vue from 'vue'
import App from './App.vue'
import { Modal } from 'vue-js-modal'
Vue.use(Modal, { componentName: 'modal' })

new Vue({
  el: '#app',
  render: h => h(App),
})

Introduce the import statement in the component, and then Use the vue-js-modal component to preview:

When we click on the image, we call this.$modal.show('preview', { src: url }), Then we can display this image.

So far, we have successfully added the image preview function. In the process of combining the Vue-awesome-swiper and vue-js-modal plug-ins, we have implemented the image carousel and image preview functions.
