Binding Data with Router-Link in Vue.js

When working with Vue.js, one of the most common tasks is to dynamically bind data to your components. This can be a bit tricky, especially when you are trying to use data values with Vue Router's router-link. In this guide, we will address a specific issue related to data binding in Vue Router and provide a clear solution to ensure that your application behaves as expected.

The Problem

Imagine you have a component with a select box that allows users to select their work profile, and you want to redirect them to a specific route based on their selection. You have declared a data variable called page, which is tied to the selected value, but when you try to use this variable in the router-link, it doesn’t seem to work as intended.

Let’s take a look at the initial implementation and identify where things can go wrong.

Initial Example Code

Here’s a snippet of the code that defines the component:

In the code above, the router-link is set with the :to property binding, which is where the error occurs.

The Solution

Replace Your Router-Link Syntax

To fix this issue, you need to modify the way you bind the to property in the router-link. The correct syntax should not include brackets ([]) when you are using string concatenation. Here’s how to do it:
