How to use routing to achieve dynamic interaction and switching of page elements in Vue?

Introduction:
In Vue, routing is an important tool for dynamic interaction and switching of page elements. By using the Vue Router plug-in, we can easily implement routing functions and make the page seamlessly switch between different components. This article will introduce how to use routing in Vue to achieve dynamic interaction and switching of page elements, and provide corresponding code examples.

1. Install the Vue Router plug-in
First, we need to install the Vue Router plug-in in the Vue project. Open the terminal, enter the project directory, and execute the following command:

npm install vue-router

After the installation is completed, we can introduce the Vue Router plug-in into the project's main.js file:

import Vue from 'vue'
import VueRouter from 'vue-router'

Then, we need to tell Vue to use the Vue Router plug-in:

Vue.use(VueRouter)

2. Configure the routing table
Next, we need to configure a routing table to define the routing relationship between pages. In the root directory of the project, create a file named router.js and write the routing configuration code in it:

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from './components/Home.vue'
import About from './components/About.vue'
import Contact from './components/Contact.vue'

Vue.use(VueRouter)

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

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

export default router

In this example, we define three routing rules . When the user accesses the root path, the Home component is displayed; when the user accesses the /about path, the About component is displayed; when the user accesses the /contact path, the Contact component is displayed.

3. Using routing in Vue components
In Vue components that need to realize dynamic interaction and switching of page elements, we can use <router-link> and <router-view> component to implement. The <router-link> component is used to create routing links, while the <router-view> component is used to display the components corresponding to the current route.

Insert the <router-link> component into the page to jump between pages:

<router-link to="/">Home</router-link>
<router-link to="/about">About</router-link>
<router-link to="/contact">Contact</router-link>

When the user clicks on these links, Vue will use the routing table to Switch the configuration to the corresponding component.

Insert the <router-view> component into the page to display the components corresponding to the current route:

<router-view></router-view>

In this way, the components corresponding to the current route will be displayed in page.

4. Achieve dynamic interaction
In addition to page switching, we can also achieve dynamic interaction of page elements through routing. We can bind dynamic data in the <router-link> component and display different links based on different data.

For example, we can dynamically generate routing links through computed properties:

<router-link v-for="item in menuItems" :key="item.id" :to="item.path">{{ item.name }}</router-link>

In the above example, we use the v-for directive based on menuItemsArray generates corresponding routing links. When the data in the menuItems array changes, the routing links are updated accordingly.

5. Summary
By using the Vue Router plug-in, we can easily achieve dynamic interaction and switching of page elements. By configuring the routing table and using the <router-link> and <router-view> components in the Vue component, we can achieve seamless page switching. At the same time, we can also realize dynamic interaction of page elements by binding dynamic data, making the page more flexible and rich.

The above is an introduction and sample code on how to use routing to achieve dynamic interaction and switching of page elements in Vue. Hope this article is helpful to you!
