How to Store Previous Page Url As String In Vue.js?

In Vue.js, you can store the previous page URL as a string by accessing the window.location.href property in the beforeRouteEnter or beforeRouteUpdate hooks of the Vue Router. You can store this value in a data property or a Vuex store for later use in your application. Additionally, you can also use the window.history API to manage page navigation and store the previous URL in a variable. By using these techniques, you can easily access and use the previous page URL in your Vue.js application.

How to store previous page URL in a database in vue.js?

To store the previous page URL in a database in Vue.js, you can create a method in your Vue component that captures the previous page URL and then sends it to a backend API to store it in a database. Here's an example of how you can achieve this:

1. Create a method in your Vue component to capture the previous page URL:

 1

 3
 4
 5
 6
 7
 8
 9
10
11
12

methods: {
  capturePreviousPageUrl() {
    const previousPageUrl = document.referrer; // Get the previous page URL from the browser
    this.storePreviousPageUrl(previousPageUrl);
  },

  async storePreviousPageUrl(url) {
    try {
      // Send a POST request to your backend API to store the previous page URL in a database
      await axios.post('/api/storePreviousPageUrl', { url });
      console.log('Previous page URL stored successfully');
    } catch (error) {
      console.error('Error storing previous page URL:', error);
    }
  }
}

1. Use the capturePreviousPageUrl method in a lifecycle hook to capture the previous page URL when the component is loaded:

1
2
3

mounted() {
  this.capturePreviousPageUrl();
}

1. Set up a backend API route to receive the previous page URL and store it in a database. This will depend on your backend technology (e.g. Node.js/Express, PHP, Ruby on Rails, etc.)
2. Handle the POST request to store the previous page URL in your backend API:

1
2
3
4
5
6

app.post('/api/storePreviousPageUrl', (req, res) => {
  const { url } = req.body;
  // Store the previous page URL in your database
  // Example: MongoClient.connect({ connection URL }, (err, db) => { db.collection('previousPageUrls').insertOne({ url }) });
  res.sendStatus(200);
});

Make sure to secure your backend route and database access to prevent unauthorized access to this sensitive information.

What is the correct syntax for saving previous page URL in vue.js?

In Vue.js, you can save the previous page URL by using the window.history object. Here is an example of how you can save the previous page URL:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

// Save previous page URL in data property
data() {
  return {
    previousPageUrl: ''
  }
},

created() {
  // Save previous page URL
  this.previousPageUrl = document.referrer;
}

In the above example, we declare a data property called previousPageUrl to store the previous page URL. We then use the document.referrer property to get the URL of the previous page and save it in the data property. This code should be placed in the created hook of the component so that it runs when the component is created.

What is the recommended practice for retaining previous page URL in vue.js applications?

In a Vue.js application, the recommended practice for retaining the previous page URL is to use the router navigation guards provided by Vue Router. One way to achieve this is by using the beforeRouteLeave guard to store the current route's URL in a variable before navigating away from the page, and then using the beforeRouteEnter guard on the next page to access and use the stored URL.

Here is an example implementation:

 1

 3

 5
 6

// In the current page component
beforeRouteLeave (to, from, next) {
  // Store the previous route's URL in a variable
  this.$store.commit('setPreviousRoute', from.path)
  next()
}

// In the next page component
beforeRouteEnter (to, from, next) {
  // Access the stored previous route's URL from the Vuex store
  const previousRoute = this.$store.state.previousRoute
  if (previousRoute) {
    // Do something with the previous route's URL
  }
  next()
}

This approach ensures that the previous page URL is retained and can be accessed whenever needed in the application. Additionally, using Vuex to store the previous route's URL allows for centralized state management and easy access across different components.

What is the best way to store previous page URL in vue.js?

One common way to store the previous page URL in Vue.js is by using Vue Router's navigation guards. You can use the beforeRouteLeave guard to store the previous page URL before navigating away from the current page.

Here is an example of how you can store the previous page URL in a Vue component:

1
2
3
4
5
6

export default {
  beforeRouteLeave (to, from, next) {
    this.$store.dispatch('storePreviousPage', from.path)
    next()
  }
}

In this example, we are using Vuex to store the previous page URL in the store. You can also store it in a local component property if you prefer.

Another way to store the previous page URL is by using the vue-router-back-button package, which provides a simple way to implement a back button that navigates to the previous page URL.

Overall, the best way to store the previous page URL in Vue.js depends on your specific requirements and use case. Choose an approach that fits your project structure and design.

How to keep track of previous page URL in vue.js?

In Vue.js, you can keep track of the previous page URL by using the beforeRouteEnter navigation guard along with the $router object.

Here's an example of how you can do this:

1. Add the beforeRouteEnter navigation guard to the component where you want to keep track of the previous page URL:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

export default {
  beforeRouteEnter (to, from, next) {
    next(vm => {
      vm.previousPageUrl = from.fullPath;
    });
  },
  data() {
    return {
      previousPageUrl: ''
    }
  },
  // Other component options
}

1. Now, you can access the previous page URL in your component methods or computed properties using this.previousPageUrl.

For example, you can log the previous page URL in a method like this:

1
2
3
4
5

methods: {
  logPreviousPageUrl() {
    console.log('Previous page URL:', this.previousPageUrl);
  }
}

This way, you can keep track of the previous page URL in Vue.js using the beforeRouteEnter navigation guard and access it in your component.
