How to use Vue and Element Plus to implement picture carousels and slideshows

In web design, picture carousels and slideshows are common functional requirements. These functions can be easily implemented using the Vue and Element Plus frameworks. This article will introduce how to use Vue and Element Plus to create a simple and beautiful picture carousel and slideshow component.

First, we need to install Vue and Element Plus. Execute the following command in the command line:

npm install vue@next
npm install element-plus@beta

Next, we can create a Vue component to implement the image carousel and slide show functions. In the component template, we can use the el-carousel and el-carousel-item components provided by Element Plus to implement the functions of carousel and display of images. The code is as follows:

<template>
  <el-carousel indicator-position="outside" arrow="always">
    <el-carousel-item v-for="(item, index) in items" :key="index">
      <img :src="item" alt="">
    </el-carousel-item>
  </el-carousel>
</template>

In the data option of the component, we can define an array to store the path of the image to be displayed. Here we use some example images.

<script>
export default {
  data() {
    return {
      items: [
        'https://example.com/image1.jpg',
        'https://example.com/image2.jpg',
        'https://example.com/image3.jpg'
      ]
    }
  }
}
</script>

Next, we need to register and use this component in the Vue instance. In the entry file, we can use the createApp function to create a Vue instance and register the component in the instance.

import { createApp } from 'vue'
import App from './App.vue'

createApp(App).mount('#app')

At this point, we have completed the creation of the image carousel and slide show components. After running the project, we will see a slideshow that automatically rotates images.

In addition to automatic carousel, Element Plus also provides some other commonly used options and methods to meet different needs. For example, we can set the rotation interval, whether to display indicators, whether to display arrows, etc.

<template>
  <el-carousel indicator-position="outside" arrow="always" :interval="4000">
    <el-carousel-item v-for="(item, index) in items" :key="index">
      <img :src="item" alt="">
    </el-carousel-item>
  </el-carousel>
</template>

On the el-carousel component, we can use the interval attribute to set the carousel interval in milliseconds.

In addition, Element Plus also provides some events and methods so that we can control the carousel. For example, we can manually switch to the next picture through the next method.

methods: {
  nextSlide() {
    this.$refs.carousel.next()
  }
}

In the template, we can call the nextSlide method through the click event of the button.

<template>
  <el-carousel ref="carousel" indicator-position="outside" arrow="always">
    ...
  </el-carousel>
  <el-button @click="nextSlide">Next Slide</el-button>
</template>

Through the above sample code, we can use Vue and Element Plus to easily implement a beautiful picture carousel and slideshow component. We can implement functions such as automatic carousel and manual switching through some simple configurations and methods to meet different needs.

To sum up, it is very simple to use Vue and Element Plus to implement image carousel and slide show functions. We only need to use the el-carousel and el-carousel-item components to display images, and control the carousel effect through some properties and methods. I hope the sample code in this article can help you quickly implement your own image carousel and slideshow functions.
