Solution to Vue error: Unable to correctly use vue-router for routing jump

When we use Vue to develop front-end projects, we often use vue-router. Page routing jump. However, sometimes we may encounter some errors when using vue-router, causing the route to fail to jump normally. This article will answer this question and give corresponding solutions.

First of all, before using vue-router, we need to ensure that the vue-router library has been installed correctly. It can be installed through the command npm install vue-router. After the installation is complete, introduce vue-router in our JS file.

import VueRouter from 'vue-router'
Vue.use(VueRouter)

Next, we need to create a routing instance and define our routes and components. The following is a simple example:

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

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes
})

export default router

In the above example, we created a routing instance through VueRouter and defined the routing path and corresponding components.

Next, in our Vue project, we need to render the corresponding component through <router-view></router-view> to display the page corresponding to the route .

However, during this process, if we do not configure routing correctly, errors may occur. Below are some common errors and their solutions.

1. Error report: Unknown custom element <router-view></router-view> or <router-link></router-link>

This error report It is generally caused by us not introducing the vue-router library correctly or not configuring routing correctly. To solve this problem, we need to ensure that the vue-router library has been correctly introduced, and use Vue.use(VueRouter) to enable vue-router in the Vue instance.

2. Error report: Cannot read property 'xxx' of undefined

  // 路由跳转
  const redirectTo = (path) => {
    if (router.currentRoute.path !== path) {
      router.push(path)
    }
  }

  redirectTo('/home')

4. Error: Error: Redirected when going from xxx to xxx via a navigation guard.

This error is usually caused by the setting we made beforeEach or beforeResolve is caused by the next() method not being called correctly after the navigation guard. To solve this problem, we need to correctly call the next() method in the navigation guard function.

The above are some common errors and their solutions. I hope it will be helpful to everyone when solving Vue errors. In actual development, we need to ensure the normal jump of routes by correctly configuring routes and using navigation guards and other techniques. At the same time, for some complex error situations, it is also necessary to check the error information and conduct step-by-step debugging to find the problem and solve it in time.
