How to open a new page in Vue

Vue is a popular JavaScript framework for developing modern web applications. Vue is designed to be flexible and easily extensible, making it ideal for building single-page applications. However, for some beginners, opening a page in Vue may be a bit difficult. In this article, we will discuss how to open a new page in Vue, as well as some of the problems you may encounter when opening the page.

First, let's look at the basic method of opening a new page in Vue. To open a new page, you need to use the routing function provided by Vue. Routing is an important concept in Vue, it is a component mapped to a URL. Routing makes navigating within the application very easy.

To use Vue routing, please first ensure that Vue Router has been installed. You can use npm or yarn to install Vue Router, as shown below:

npm install vue-router

or

yarn add vue-router

After the installation is complete, you can use Vue Router. First, you need to create a router instance in the Vue application, as shown below:

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

Vue.use(VueRouter)

const router = new VueRouter({
  routes: [
    {
      path: '/',
      name: 'Home',
      component: Home
    },
    {
      path: '/about',
      name: 'About',
      component: About
    }
  ]
})

In this example, a router instance is created and two routes are defined: one for the homepage and the other for about page. Each route has a URL path (path), a name (name), and a component (component). These routes will be used in the Vue application.

Next, you need to use the created router instance in your Vue application. The router attribute can be used in the root instance of the Vue application as shown below:

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

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

Now that a basic routing configuration has been created, the next step is to open a new page in Vue.

To open a new page in Vue, you need to use the v-router-link command provided by Vue Router. The v-router-link directive is used in Vue to create a clickable link that can navigate the user from one page to another.

For example, to create a navigation menu in Vue that includes a link to the About page, you can use the following code:

<router-link to="/about">About</router-link>

In this example, v-router-link The directive is used to create a link to the "About" page. The to attribute specifies the URL path of the link. When the user clicks the link, Vue Router will navigate to the component mapped by this URL path.

Now that you know the basic method of opening a new page in Vue, let's look at some of the problems you may encounter when opening the page.

The first question is how to access URL parameters in the new page. To access URL parameters in Vue, you can use the $route object. The $route object contains information about the current route, including URL parameters and query parameters. For example, the parameter is accessed in the following URL path:

/about/:id

The ID parameter can be accessed in Vue using the following code:

this.$route.params.id

The second question is how to open an external link in Vue. To open an external link in Vue, you can use the target attribute of the v-router-link directive provided by Vue Router. For example, open an external link in the following Vrouter-link directive:

<router-link to="https://www.example.com" target="_blank">Example</router-link>

In this example, the target attribute is used to open a new window and link to the external URL.
