Challenge - 5 Problems

What happens when you click this RouterLink?

Consider this Vue RouterLink component:

<RouterLink to="/about">About</RouterLink>

What will the user see after clicking this link?

Vue

<RouterLink to="/about">About</RouterLink>

A An error is shown because 'to' must be an object, not a string.

B Nothing happens because RouterLink requires a click handler.

C The browser navigates to the '/about' route without reloading the page.

D The browser reloads the entire page and navigates to '/about'.

💡 Hint

RouterLink is designed to navigate inside the app without full page reload.

RouterLink uses Vue Router to change routes smoothly without reloading the page, improving user experience.

📝 Syntax

Which RouterLink syntax correctly navigates to a dynamic user profile with id 42?

You want to create a RouterLink to '/user/42'. Which syntax is correct?

A <RouterLink :to="{ path: '/user/42' }">Profile</RouterLink>

B <RouterLink to="/user/42">Profile</RouterLink>

C <RouterLink to="{ path: '/user/42' }">Profile</RouterLink>

D <RouterLink :to="'/user/' + 42">Profile</RouterLink>

💡 Hint

Use binding with an object for dynamic routes.

Using :to with an object allows Vue Router to handle the route properly. Option A is invalid because it lacks binding.

What is the active class applied to this RouterLink when on '/home' route?

Given this RouterLink:

<RouterLink to="/home" active-class="active-link">Home</RouterLink>

If the current route is '/home', what class will the rendered anchor tag have?

Vue

<RouterLink to="/home" active-class="active-link">Home</RouterLink>

A The anchor tag will have the class 'router-link-active'.

B The anchor tag will have the class 'active-link'.

C The anchor tag will have no class applied.

D The anchor tag will have the class 'active'.

💡 Hint

Check the active-class prop usage.

The active-class prop overrides the default 'router-link-active' class with 'active-link' when the link is active.

Why does this RouterLink cause a navigation error?

Look at this RouterLink code:

<RouterLink :to="{ name: 'profile', params: { userId: 5 } }">User</RouterLink>

The route named 'profile' expects a param called 'id', not 'userId'. What error will happen?

Vue

<RouterLink :to="{ name: 'profile', params: { userId: 5 } }">User</RouterLink>

A Navigation fails because the required 'id' param is missing.

B Navigation succeeds and goes to '/profile/5'.

C A syntax error occurs due to incorrect param naming.

D The link renders but clicking it does nothing.

💡 Hint

Route params must match the route definition exactly.

The route expects 'id' param, but 'userId' is given, so navigation fails due to missing required param.

How does RouterLink improve accessibility compared to a plain anchor tag?

Which of the following best explains how Vue's RouterLink component helps with accessibility?

A RouterLink requires manual ARIA labels to be accessible.

B RouterLink disables keyboard navigation to prevent accidental route changes.

C RouterLink replaces anchor tags with buttons which are more accessible.

D RouterLink automatically manages keyboard focus and ARIA attributes for SPA navigation.

💡 Hint

Think about SPA navigation and keyboard users.

RouterLink renders anchor tags with proper roles and manages focus to ensure keyboard users can navigate routes smoothly.
