How to use routing to implement page scrolling control and positioning in Vue?

In Vue applications, routing can be used to achieve jumps and navigation between pages. In addition to the basic jump function, we can also use routing to achieve page scrolling control and positioning, improving user experience and page navigation effects. This article will introduce how to use routing to implement page scrolling control and positioning in Vue, and provide code examples for reference.

First, we need to install and introduce Vue Router, which is the routing manager officially provided by Vue, in the Vue project. You can use npm to install Vue Router, and introduce and use it in the project's entry file.

// main.js

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

Vue.config.productionTip = false

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

Next, we need to define the routing configuration in the Vue project. In the routing configuration, we can specify the components and paths corresponding to each route, and also add scrolling behavior and scrolling position configuration.

// router.js

import Vue from 'vue'
import Router from 'vue-router'
import Home from './views/Home.vue'
import About from './views/About.vue'

Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home,
      meta: { scrollToTop: true } // 指定是否需要滚动到页面顶部
    },
    {
      path: '/about',
      name: 'about',
      component: About,
      meta: { scrollToTop: false } // 指定无需滚动到页面顶部
    }
  ],
  scrollBehavior(to, from, savedPosition) {
    if (savedPosition) {
      return savedPosition
    } else {
      if (to.meta.scrollToTop) {
        return { x: 0, y: 0 }
      }
    }
  }
})

In the above code, we created two routes, corresponding to the homepage and about page. By adding the scrollToTop parameter in the meta field of the route configuration, we can control whether we need to scroll to the top of the page. In the scrollBehavior function, we determine whether to scroll to the top based on the value of to.meta.scrollToTop.

Now, we can use routing in the Vue component to implement page scrolling control and positioning. Where you need to jump to a certain page, use the tag or programmatic navigation to trigger the routing jump.

<!-- Home.vue -->

<template>
  <div class="home">
    <h1>Welcome to Home Page</h1>
    <router-link to="/about">Go to About Page</router-link>
  </div>
</template>

<!-- About.vue -->

<template>
  <div class="about">
    <h1>Welcome to About Page</h1>
    <router-link to="/">Go to Home Page</router-link>
  </div>
</template>

In the above code, we define links to jump to the about page and homepage through the tag.

Finally, in the App.vue root component in the Vue project, add the tag to display the content of the page corresponding to the current route.

<!-- App.vue -->

<template>
  <div id="app">
    <router-view></router-view>
  </div>
</template>

So far, we have completed the configuration and use of using routing to achieve page scrolling control and positioning in Vue.

Summary:

Through the routing configuration and scrolling behavior functions provided by Vue Router, we can easily realize jumps and navigation between pages, and control the page scrolling position. By adding the configuration of the meta field and scrollBehavior function, we can achieve the effect of scrolling to the top when switching pages and improve the user experience. Of course, this is just a simple example of using routing to implement page scrolling control and positioning in Vue. We can make more complex configurations and customizations based on specific project needs.
