How to implement image browsing and thumbnail navigation through Vue?

With the development of web applications, pictures play an increasingly important role in our daily lives. In many cases, we need to implement image browsing and thumbnail navigation functions. This article will introduce how to use the Vue framework to implement this function and provide code examples.

In Vue, we can use the Vue plug-in to implement image browsing and thumbnail navigation functions. A popular plugin is vue-gallery, which provides an easy-to-use interface and rich functionality.

First, we need to install the vue-gallery plug-in in the project. We can use the npm command to install it:

npm install vue-gallery
Copy after login

Once the installation is complete, we can introduce and use it in the Vue component. Here is a simple example:

<template>
  <div>
    <vue-gallery :images="images"></vue-gallery>
  </div>
</template>

<script>
import VueGallery from 'vue-gallery'

export default {
  components: {
    VueGallery
  },
  data() {
    return {
      images: [
        'image1.jpg',
        'image2.jpg',
        'image3.jpg'
      ]
    }
  }
}
</script>
Copy after login

In the above example, we used Vue’s single-file component structure. We import vue-gallery as a custom component and use it in the template. We specify the images to display by passing an array containing the image paths to the images property of vue-gallery.

vue-gallery plug-in will automatically generate thumbnail navigation for us, and we can browse the large image by clicking on the thumbnail. It also provides many customization options so that we can adjust it according to our actual needs.

In addition to using the vue-gallery plug-in, we can also implement image browsing and thumbnail navigation functions by writing our own Vue components. Here is an example:

<template>
  <div>
    <div class="thumbnails">
      <div
        v-for="(image, index) in images"
        :key="index"
        :class="{'selected': currentIndex === index}"
        @click="changeImage(index)"
      >
        <img :src="image.thumbnail" alt="">
      </div>
    </div>
    <div class="main-image">
      <img :src="images[currentIndex].src" alt="">
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentIndex: 0,
      images: [
        { src: 'image1.jpg', thumbnail: 'thumbnail1.jpg' },
        { src: 'image2.jpg', thumbnail: 'thumbnail2.jpg' },
        { src: 'image3.jpg', thumbnail: 'thumbnail3.jpg' }
      ]
    }
  },
  methods: {
    changeImage(index) {
      this.currentIndex = index
    }
  }
}
</script>
Copy after login

In the above example, we use the v-for directive and an array to dynamically generate thumbnail navigation. We use a variable to keep track of the currently selected image and update it when the user clicks on the thumbnail. The main image section uses the currently selected image path to display the larger image.

Through the above examples, we can see that it is not complicated to use the Vue framework to implement image browsing and thumbnail navigation. Whether using existing plug-ins or writing components ourselves, we can extend and customize them according to actual needs.
