How to Get the Current Active Route In Vue.js?

To get the current active route in Vue.js, you can utilize the Vue Router. Here is how you can achieve it in three simple steps:

1. Import the Vue Router module in your component:

1

import { useRouter } from "vue-router";

1. Use the useRouter() function to get the router instance:

1

const router = useRouter();

1. Access the current active route using the $route property:

1

const currentRoute = router.currentRoute;

That's it! Now you have the current active route stored in the currentRoute variable. You can access various properties of the current route, such as path, name, params, query, etc., to perform specific actions based on the current route.

How to obtain the previous route's query parameters in Vue.js?

In Vue.js, you can obtain the previous route's query parameters using the $route object. The $route object contains information about the current route, including the query parameters.

To obtain the previous route's query parameters, you need to store the current route's query parameters when navigating to a new route. You can do this by using the beforeRouteLeave navigation guard to capture the current query parameters and store them in a variable or a Vuex store.

Here's an example of how you can obtain the previous route's query parameters in Vue.js:

1. Define a variable or a Vuex store to store the previous route's query parameters. For example:

 1

// store.js
import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default new Vuex.Store({
  state: {
    previousQueryParams: null,
  },
  mutations: {
    setPreviousQueryParams(state, queryParams) {
      state.previousQueryParams = queryParams
    },
  },
})

1. In your Vue component, import the store and access the previousQueryParams state:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

// MyComponent.vue
import store from '@/store'

export default {
  // ...

  created() {
    const previousQueryParams = store.state.previousQueryParams
    console.log(previousQueryParams) // or do something else with the query parameters
  },

  // ...
}

1. In your Vue router configuration, add the beforeRouteLeave navigation guard to capture the previous route's query parameters and store them in the store:

 1
 2
 3
 4
 5

 7

// router.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import store from '@/store'

Vue.use(VueRouter)

const router = new VueRouter({
  // ...
})

router.beforeRouteLeave((to, from, next) => {
  store.commit('setPreviousQueryParams', from.query)
  next()
})

export default router

Now, whenever you navigate to a new route, the previous route's query parameters will be stored in the store's previousQueryParams state. You can then access and use these query parameters in your Vue components.

What is the Vue.js function to retrieve the current route's query parameters?

The Vue.js function to retrieve the current route's query parameters is $route.query.

You can access it in a component using this.$route.query. It returns an object containing all the query parameters of the current route.

What is the Vue.js function to check if a particular route is active by name?

The Vue.js function to check if a particular route is active by name is called $route.matched.some().

Here's an example usage:

1
2
3

this.$route.matched.some(route => {
    return route.name === 'your-route-name';
});

In this code snippet, your-route-name should be replaced with the name of the route you want to check. This function returns true if the route is active and false otherwise.

How do I get the current route's full path in Vue.js?

In Vue.js, you can access the current route's full path using the $route object. The $route object contains information about the current route, including the path.

To get the full path, you can use the $route.path property. Here's how you can access it in your Vue component:

 1

 3

<template>
  <div>
    {{ $route.path }}
  </div>
</template>

<script>
export default {
  mounted() {
    console.log(this.$route.path);
  },
};
</script>

In the template, you can simply use {{ $route.path }} to display the full path of the current route. In the mounted() lifecycle hook or other methods, you can access it using this.$route.path.

Note that this will give you the path without the base URL or the hash if using hash mode. If you need the full URL, including the base URL or the hash, you can use the $router.currentRoute.fullPath, like this:

 1

 3
 4
 5

<template>
  <div>
    {{ $router.currentRoute.fullPath }}
  </div>
</template>

<script>
export default {
  mounted() {
    console.log(this.$router.currentRoute.fullPath);
  },
};
</script>

This will give you the full URL of the current route, including the base URL or the hash.

Remember to import the necessary Vue Router components and set up your routes properly for this to work.

How do I access the current route object in Vue.js?

In Vue.js, you can access the current route object using the $route object. Here are a few ways to do that:

1. In a Vue component's template: You can directly access the route object by using the $route object. For example, you can display the current route's path by using {{ $route.path }} in your template.
2. In a Vue component's script: You can access the current route object using this.$route. For example, you can log the current route's params by using console.log(this.$route.params).
3. In a Vue router navigation guard: When using the Vue Router, you can access the current route object in the to or from arguments of the navigation guard functions. For example, in the beforeEach navigation guard, you can access the current route object using to or from parameters:

1
2
3
4

router.beforeEach((to, from, next) => {
  console.log(to.path) // Current route's path
  next()
})

These are some of the common ways to access the current route object in Vue.js. Choose the method that suits your use case the best.

What is the Vue.js method to determine if the current route is a child route?

The Vue.js method to determine if the current route is a child route is this.$route.matched.length > 1.

What is the Vue.js function to get the current route's hash value?

In Vue.js, you can use $route.hash to get the current route's hash value.
