With the popularity of mobile devices such as mobile phones, APP development has become the focus of more and more programmers. APP development needs to take into account a variety of performance factors, such as memory usage, bandwidth, etc. In order to solve this problem, uniapp came into being, which is also a very powerful development tool. However, as a newbie, do you know whether you can use the swiper plug-in when developing with uniapp? This article will explore this issue.

First of all, we need to understand the concepts of uniapp and swiper plug-ins. uniapp is a cross-platform development framework based on the Vue.js framework. It can publish code to various platforms at the same time (most APP platforms, mini program platforms, H5, quick applications, etc.), allowing developers to Applications for each platform are built based on the code. The swiper plug-in is a JavaScript-based touch and slide plug-in library for mobile devices that can quickly realize various touch and slide effects on desktop and mobile devices.

Based on the above concepts, we can conclude that uniapp can use the swiper plug-in. Specifically, using uniapp for development can easily install, reference and use the swiper plug-in, and can also well meet the cross-platform development needs of applications.

So, how do we use the swiper plug-in through uniapp? The following are the specific steps:

Step 1: Download the swiper plug-in

Before using the swiper plug-in, you need to download the plug-in first. On the GitHub website, you can find the official installation instructions for swiper, which is very simple to operate.

In the root directory of the local project folder, open the terminal and enter the following commands to download swiper.

npm install swiper --save

After entering the above command, the system will automatically download the swiper plug-in package and install it in your project folder.

Step 2: Introduce the swiper plug-in

After the download is completed, you need to introduce the required swiper components to the page where you need to use swiper. You can use the following code to introduce swiper in your page component (.vue file):

<template>
  <swiper :options="swiperOption">
    <swiper-slide>Slide 1</swiper-slide> 
    <swiper-slide>Slide 2</swiper-slide> 
    <swiper-slide>Slide 3</swiper-slide> 
    <swiper-slide>Slide 4</swiper-slide> 
  </swiper>
</template>

<script>
  import Swiper from 'swiper';
 
  export default {
    data() {
      return {
        swiperOption: {
          loop: true,
          autoplay: 3000,
          pagination: '.swiper-pagination',
        }
      }
    },
    mounted(){
      this.swiper = new Swiper('.swiper-container', this.swiperOption);
    }
  }
</script>

<style>
  .swiper-slide {
    text-align: center;
    font-size: 18px;
    background: #fff;
 
    /* Center slide text vertically */
    display: -webkit-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-box-pack: center;
    -ms-flex-pack: center;
    -webkit-justify-content: center;
    justify-content: center;
    -webkit-box-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
  }
</style>

In the above code, we introduced the swiper component through the import statement, and in the virtual DOM Use the <swiper> tag to define the swiper container. The swiperOption object here is the setting of the swiper component option, which needs to be changed according to actual needs.

The mounted() function is the callback function after the swiper component is rendered. In the function, we initialize the swiper component through the new Swiper() statement. It should be noted that here we pass two parameters to new Swiper():

  • .swiper-container: container with class swiper-container;
  • this.swiperOption: The option list whose name is swiperOption.

Step 3: Use the swiper plug-in

After the above process is completed, you can use the swiper plug-in smoothly. Next, we traverse the data through the v-for directive and nest the <swiper-slide> tag in the swiper container. At the same time, we set up the paginator and navigation tag in swiper (see code for details).

<template>
  <swiper :options="swiperOption">
    <swiper-slide v-for="(item,index) in list" :key="index">
      {{item.name}}
    </swiper-slide>
    <div class="swiper-pagination"></div>
    <div class="swiper-button-prev"></div>
    <div class="swiper-button-next"></div>
  </swiper>
</template>

<script>
  import Swiper from 'swiper';
 
  export default {
    data() {
      return {
        list: [
          {name: 'Slide 1'}, {name: 'Slide 2'},
          {name: 'Slide 3'}, {name: 'Slide 4'}
        ],
        swiperOption: {
          loop: true,
          autoplay: 3000,
          pagination: '.swiper-pagination',
          navigation: {
            nextEl: '.swiper-button-next',
            prevEl: '.swiper-button-prev',
          },
        },
      };
    },
    mounted(){
      this.swiper = new Swiper('.swiper-container', this.swiperOption);
    }
  };
</script>

<style>
  .swiper-slide{
    height: 100px;
    line-height: 100px;
    text-align: center;
    font-size: 18px;
    background: #fff;
  }
</style>

In the above code, the <swiper-slide> label represents each slider in the swiper container, and the data is traversed through v-for, Realized the dynamic display of swiper sliding container. In the swiper options, we define some attribute values ​​​​of this swiper, such as the index of the initial display, whether to automatically play, paginator, etc. These values ​​​​will continue to change with the use of the swiper component.

Summary

Nowadays, uniapp is a cross-platform development framework that is increasingly popular among developers. The swiper plug-in is a powerful touch sliding plug-in library for mobile devices. It is easy to use the swiper plug-in in uniapp. You only need to complete the respective download, import and definition operations, and then you can start using the plug-in.

Of course, we also need to note that using plug-ins can easily increase the load of the page, so please consider it carefully during actual development and make reasonable choices based on actual needs.
