vue + change router link active class

To change the router link active class in Vue.js, you can follow these steps:

1. In your Vue component, locate the router-link element that you want to modify.

2. Add the attribute ":class" to the router-link element to bind the class dynamically.

3. Inside the ":class" attribute, use an object to define the classes that should be applied based on certain conditions. Use the "active" class as a key and set it to true to apply the class when the link is active.

4. Use the "$route" object to check if the current route matches the link's path. Use the "name" property if the link is named, or use the "path" property if the link has a path.

5. Apply the "active" class conditionally based on whether the current route matches the link's path.

By following these steps, you can dynamically change the router link active class in your Vue.js application.
