Vue routing login does not jump

Vue is a popular JavaScript framework for building single-page applications (SPA). In Vue, routing is a very important part and is used to create navigation between different pages within the application. However, when trying to implement the login function in a Vue application, sometimes there may be a problem that the routing login does not jump. This article will explore how to solve this problem.

Problem Description:

In a Vue application, when a user tries to log in, the application uses routing for login verification. If the verification is successful, it should jump to another page of the application, otherwise it should stay on the current login page and display an error message. However, sometimes after successful login verification, the application fails to jump to the next page correctly. Instead, it just stays on the current login page without anything happening.

This problem is usually caused by a configuration error in Vue routing or Vue Router. Here are possible solutions:

Solution:

1. Check the route definition

First, make sure the Vue route is defined correctly. In a Vue application, route definitions typically include route paths and component names. If routes are not defined correctly, the application will not be able to correctly parse the URL and jump to the appropriate page. Make sure routing paths and component names correspond to those defined in the Vue instance.

For example, here is an example of a simple Vue route definition:

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '@/views/Home.vue'
import Login from '@/views/Login.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'home',
    component: Home
  },
  {
    path: '/login',
    name: 'login',
    component: Login
  }
]

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

export default router

In this example, we have two paths: '/' and '/login', which correspond to Home. vue and Login.vue components.

2. Check the login logic

Secondly, make sure that the routing jump is set correctly in the login logic. In Vue applications, a common practice is to use Vue Router's $router.push() method in login logic to jump to the next page.

For example, the following is a simple login component example:

<template>
  <div>
    <form>
      <label>Email</label>
      <input type="email" v-model="email" required>
      <label>Password</label>
      <input type="password" v-model="password" required>
      <button type="submit" @click.prevent="login">Login</button>
    </form>
    <div v-if="errorMessage">{{ errorMessage }}</div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      email: '',
      password: '',
      errorMessage: ''
    }
  },
  methods: {
    login() {
      if (this.email === 'test@example.com' && this.password === 'password') {
        this.$router.push({ name: 'home' })
      } else {
        this.errorMessage = 'Invalid credentials'
      }
    }
  }
}
</script>

In this example, we use the $router.push() method to redirect the user to a directory called " home" route.

3. Fix routing configuration errors

Finally, if neither of the above two solutions solve your problem, you may need to recheck the configuration of Vue routing. In particular, if you are using a route configuration with nested paths, make sure that the path between the child route and the parent route is specified correctly.

For example, here is an example of a Vue route with nested paths:

const router = new VueRouter({
  mode: 'history',
  base: process.env.BASE_URL,
  routes: [
    {
      path: '/',
      name: 'home',
      component: Home
    },
    {
      path: '/users',
      component: {
        template: '<router-view/>'
      },
      children: [
        {
          path: '',
          name: 'users',
          component: Users
        },
        {
          path: ':id',
          name: 'user',
          component: UserProfile
        }
      ]
    }
  ]
})

In this example, we have a "users" path that contains the names "users" and " user" subpath. Please make sure you specify the parent-child relationship and path correctly when defining the route.

Conclusion:

In a Vue application, routing is a very important part. When implementing the login function, sometimes there will be a problem that the routing login does not jump. If you encounter this issue, check the route definition, login logic, and route configuration to make sure they are correct. If none of the above solutions solve your problem, please refer to the Vue Router documentation or ask for help in the Vue community.
