How to use Vue to implement web page scrolling effects

With the continuous development of the Internet, web design has paid more and more attention to user experience, especially in terms of scrolling effects. Scroll effects can add dynamics and interactivity to web pages. This article will introduce how to use Vue to implement web page scrolling effects and provide specific code examples.

1. Install Vue and Vue Router
   First, we need to install Vue and Vue Router. Run the following command in the terminal:

npm install vue vue-router

2. Create Vue instance and route
   In the main.js file, we create the Vue instance and route. The code example is as follows:

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App.vue'

Vue.use(VueRouter)

const routes = [
  { path: '/', component: Home },
  { path: '/about', component: About },
  { path: '/contact', component: Contact }
]

const router = new VueRouter({
  mode: 'history',
  routes
})

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

3. Create a scrolling effect component
   Create a components folder in the src directory, and then create a ScrollAnimation.vue component in the folder. The code example is as follows:

<template>
  <div class="scroll-animation-container">
    <div :class="{ animate: isScrolling }" ref="animateEl"></div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      isScrolling: false
    }
  },
  mounted() {
    window.addEventListener('scroll', this.handleScroll)
  },
  methods: {
    handleScroll() {
      const animateEl = this.$refs.animateEl
      const offsetTop = animateEl.offsetTop
      const windowHeight = window.innerHeight
      const scrollTop = window.scrollY

      if (scrollTop > offsetTop - windowHeight) {
        this.isScrolling = true
      } else {
        this.isScrolling = false
      }
    }
  },
  beforeDestroy() {
    window.removeEventListener('scroll', this.handleScroll)
  }
}
</script>

<style>
.scroll-animation-container {
  width: 100%;
  height: 300px;
  background-color: #f2f2f2;
}

.animate {
  width: 100%;
  height: 300px;
  background-color: #ff9900;
  opacity: 0;
  transition: opacity 0.5s;
}

.animate.isScrolling {
  opacity: 1;
}
</style>

4. Using the scrolling effect component in routing
   In the App.vue file, we use the scrolling effect component. The code example is as follows:

<template>
  <div id="app">
    <router-link to="/">Home</router-link>
    <router-link to="/about">About</router-link>
    <router-link to="/contact">Contact</router-link>

    <router-view></router-view>

    <scroll-animation></scroll-animation>
  </div>
</template>

<script>
import ScrollAnimation from './components/ScrollAnimation.vue'

export default {
  components: {
    ScrollAnimation
  }
}
</script>

<style>
#app {
  text-align: center;
  padding-top: 60px;
}
</style>

5. Writing style files and routing components
   Create a styles folder in the src directory, and create a main.scss file in the folder, using For writing universal styles. For example, we can set global styles and layout of web pages.

Create a views folder in the src directory, and create the Home.vue, About.vue and Contact.vue components respectively in the folder, and write the corresponding styles and content.

6. Start the application
   Finally, run the following command in the terminal to launch the application:

npm run serve
