How to solve the Vue error: Unable to correctly use Vue Router for route jump

In Vue development, it is very common to use Vue Router for route jump. However, sometimes you encounter some problems, such as incorrect route jumps or errors. This article describes some common problems and solutions, along with code examples.

Problem 1: Route jump is invalid

Sometimes when calling router.push() or router.replace(), the route jumps The transfer may be invalid. This is usually caused by not setting the correct routing path. First, make sure your route definition is correct and matches the path you want to redirect. Secondly, you need to confirm whether you are using the correct router-view component to render the route view. The following is a sample code:

// 路由定义
const router = new VueRouter({
  routes: [
    {
      path: '/home',
      component: Home
    },
    // 其他路由定义...
  ]
})

// App.vue
<template>
  <div>
    <router-link to="/home">Home</router-link>
    <router-view></router-view>
  </div>
</template>

Problem 2: Vue component is not registered or not imported

When using Vue Router, you need to ensure that your routing component is using has been imported or registered correctly before. If you forget to register a component, an error will be reported when routing. The following is a sample code:

// 路由定义
import Home from './components/Home.vue' // 忘记导入Home组件

const router = new VueRouter({
  routes: [
    {
      path: '/home',
      component: Home // 忘记注册Home组件
    },
    // 其他路由定义...
  ]
})

// App.vue
<template>
  <div>
    <router-link to="/home">Home</router-link>
    <router-view></router-view>
  </div>
</template>

Problem 3: Duplicately named routing paths

If you have duplicate paths in the routing definition, an error will be reported when performing routing jumps. This is because Vue Router cannot differentiate between two routes with the same path. Therefore, make sure your routing path is unique. The following is a sample code:

// 路由定义
const router = new VueRouter({
  routes: [
    {
      path: '/home',
      component: Home
    },
    // 重复路径
    {
      path: '/home',
      component: About
    },
    // 其他路由定义...
  ]
})

// App.vue
<template>
  <div>
    <router-link to="/home">Home</router-link>
    <router-view></router-view>
  </div>
</template>

Problem 4: this.$router and this.$route

are not used correctly in Vue components , when performing route jump, you need to use this.$router to call the push() or replace() method, use this.$ route to obtain current routing information. If you do not use these two methods correctly, routing errors will occur. The following is a sample code:

methods: {
  goToHome() {
    // 错误：没有使用this.$router
    router.push('/home')
  },
  getCurrentRoute() {
    // 错误：没有使用this.$route
    console.log(route.path)
  }
}

Through the above example, you can learn how to solve some common Vue Router error problems. By carefully checking the route definition, whether the component is registered, and using this.$router and this.$route correctly, I believe you can solve most routing problems. Of course, if you encounter other problems when using Vue Router, you can get more help by consulting the Vue Router official documentation.
