How to use Vue to implement TikTok-like sliding effects

Abstract: This article will introduce how to use the Vue framework to implement TikTok-like sliding effects. By using Vue componentization, combined with CSS3 animation effects and Vue commands, we can create a sliding effect similar to Douyin. This article will explain in detail how to write the corresponding code examples.

1. Create Vue project
   First, we need to create a new Vue project. Execute the following command in the terminal:

   $ vue create douyin-slider

   Copy after login

   Then configure the project according to the command line prompts and select the default options.

2. Create Slider component
   Create a folder named Slider in the src/components directory. Create the Slider.vue file in the Slider folder and write the following code:

   <template>
     <div class="slider">
    <div class="slider-content">
      <!-- 此处填充内容 -->
    </div>
     </div>
   </template>
   
   <script>
   export default {
     name: "Slider",
     data() {
    return {};
     },
   };
   </script>
   
   <style scoped>
   .slider {
     width: 100%;
     height: 100vh;
     background-color: #f0f0f0;
     overflow-x: hidden;
     position: relative;
   }
   
   .slider-content {
     width: 100%;
     height: 100%;
     display: flex;
     position: absolute;
     transition: transform 0.3s;
   }
   </style>

   Copy after login
3. Writing animation effects
   Introduce the required pictures or videos into the Slider component and use v in the template The -for directive renders a series of content. Then bind a sliding event to the slider-content element and achieve the sliding effect by changing its transform attribute.

In the Slider.vue file, modify the code in the template part as follows:

<template>
  <div class="slider">
    <div class="slider-content" ref="contentRef">
      <div class="item" v-for="(item, index) in items" :key="index">
        <!-- 此处填充item的内容 -->
      </div>
    </div>
  </div>
</template>

Then add the following code in the script:

<script>
export default {
  name: "Slider",
  data() {
    return {
      items: [
        // 此处填充内容数组
      ],
    };
  },
  mounted() {
    const $content = this.$refs.contentRef;

    let startX = null;

    $content.addEventListener("touchstart", (event) => {
      startX = event.touches[0].clientX;
    });

    $content.addEventListener("touchmove", (event) => {
      if (startX) {
        const distance = event.touches[0].clientX - startX;
        $content.style.transform = `translateX(${distance}px)`;
      }
    });

    $content.addEventListener("touchend", () => {
      startX = null;
      $content.style.transform = "translateX(0)";
    });
  },
};
</script>

4. Create App component
   Create a folder named App in the src/components directory, create the App.vue file in it, and write the following code:

   <template>
     <div class="app">
    <Slider />
     </div>
   </template>
   
   <script>
   import Slider from "./Slider/Slider.vue";
   
   export default {
     name: "App",
     components: {
    Slider,
     },
   };
   </script>
   
   <style scoped>
   .app {
     width: 100%;
     height: 100%;
     display: flex;
     align-items: center;
     justify-content: center;
   }
   </style>

   Copy after login

5. Modify main.js file
   Find the main.js file in the src directory and add the following code:

   import Vue from "vue";
   import App from "./components/App/App.vue";
   
   Vue.config.productionTip = false;
   
   new Vue({
     render: (h) => h(App),
   }).$mount("#app");

   Copy after login

6. Run the project
   Execute the following command in the terminal to start the project:

   $ npm run serve

   Copy after login

   Then open http://localhost:8080 in the browser, and you will see the page with imitating Douyin sliding effects.

Summary:
By using the Vue framework, combined with CSS3 animation effects and instructions, we can easily implement TikTok-like sliding effects. In the Slider component, use the v-for instruction to render a series of content, and bind sliding events to achieve the sliding effect.
