How to activate parent route in vue sub-routing

Vue is a popular JavaScript framework for creating dynamic web interfaces. It provides some useful features such as componentization, routing, etc.

In Vue, routing is a very useful feature. Vue Router is the official routing manager of Vue.js. It is deeply integrated with the Vue.js core and can easily work with other third-party libraries or plug-ins.

In Vue Router, routing is composed of a routing object and a corresponding component. In actual development, sometimes we need to activate the parent route in the child route to achieve more flexible page navigation.

In this article, we will introduce how to activate the parent route using the child route of Vue Router.

1. Set sub-routes in parent routes

First, we need to define sub-routes in parent routes. We can use the sub-routing function of Vue Router to achieve this. For example:

const routes = [
  {
    path: '/parent',
    component: Parent,
    children: [
      {
        path: 'child',
        component: Child
      }
    ]
  }
]

In the above code, we define a parent route '/parent' whose component is Parent. In Parent, we define a sub-route 'child' whose component is Child. Now, we have set up the child route in the parent route.

2. Define the exit of the sub-route in the parent route

Next, we need to set the exit of the sub-route in the parent component. In Vue, components can be nested within other components, and the content of subcomponents can be displayed in parent components in the form of slots. We can display the content of the child route by setting a slot in the parent component.

For example, we can add a tag in the template of the parent component to display the content of the child route:

<template>
  <div>
    <h1>Parent Component</h1>
    <router-view></router-view>
  </div>
</template>

3. Activate the parent in the child route Routing

Now that we have defined the sub-route in the parent route and set the exit of the sub-route in the parent component, the next step is to activate the parent route in the sub-route.

To activate the parent route, we can use the $router.push() method in the component of the child route to jump to the path of the parent route. For example:

// child.vue
export default {
  methods: {
    goParent() {
      this.$router.push('/parent')
    }
  }
}

In this example, we define a goParent method in the component of the child route. When calling the goParent method, we use the $router.push() method to jump to the path of the parent route '/parent'.

In this way, we can achieve the effect of activating the parent route in the child route.

Summary

In this article, we introduced how to use child routes to activate parent routes in Vue Router. The specific steps are as follows:

1. Define the sub-route in the parent route
2. Set the exit of the sub-route in the parent component
3. Use $router.push in the sub-route () method to jump to the path of the parent route

Through the above steps, we can easily achieve the effect of activating the parent route in the child route, thereby managing page navigation more flexibly.
