How to use Router to implement redirection function in Vue project

In a Vue project, we often need to implement jump and redirection functions between pages. Vue Router provides a simple yet powerful solution. This article will introduce how to use Router to implement the redirection function in a Vue project and give specific code examples.

1. Install Vue Router
   First, we need to install Vue Router in the Vue project. You can install it through npm or yarn. Open the terminal and enter the following command:

npm install vue-router

or

yarn add vue-router

Vue Router. After the installation is complete, we can proceed to the next step of configuration.

2. Create routing configuration file
   In the root directory of the Vue project, create a router.js file and open it. In this file, we need to introduce Vue and Vue Router, and create an instance named router.

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

Vue.use(VueRouter);

const router = new VueRouter({
  mode: 'history',
  routes: [
    // 在這里配置路由
  ],
});

export default router;

In the above code, we set the Router mode to 'history', which can remove the # symbol in the URL and make the URL more beautiful.

3. Configure redirection
   In the router.js file, we can add a redirection rule. Add an object in the routes array and configure the path and redirect properties as follows:

const router = new VueRouter({
  mode: 'history',
  routes: [
    {
      path: '/',
      redirect: '/home',
    },
    // 其他路由配置
  ],
});

In the above example, we redirect the page with the path '/' to '/home' . That is, when the user accesses the root path, we will redirect the page to '/home' and display that page instead.

4. Using redirection
   Using redirection in Vue components is very simple. In components that require redirection, we can use the $router object provided by Vue Router to jump to the page. Here is an example:

<template>
  <div>
    <h1>Home</h1>
    <button @click="redirectToAbout">Go to About Page</button>
  </div>
</template>

<script>
export default {
  methods: {
    redirectToAbout() {
      this.$router.push('/about');
    },
  },
};
</script>

In the above code, we have added a button in the Home component. When the button is clicked, the redirectToAbout method will be called, redirecting the page to '/about' through the $router.push method.

In this way, we successfully implemented the redirection function using Vue Router. Not only that, Vue Router also provides many other functions, such as dynamic routing, routing parameters, etc., which can be used as needed.

Summary
Through the above steps, we can use Vue Router to implement the redirection function in the Vue project. First install and configure Vue Router, then add redirection rules in the routing configuration file, and finally call the $router.push method in the component to redirect. I hope the sample code in this article can help you better understand and use Vue Router.
