💡 Hint

Common Mistakes

Using .stop instead of .prevent stops event propagation but not default action.

Using .once does not prevent default behavior.

The .prevent modifier stops the default action, like submitting a form.

2fill in blank

medium

Complete the code to stop the click event from bubbling up.

Vue

<button @click[1]="handleClick">Click me</button>

Drag options to blanks, or click blank then click option'

A.stop

B.once

C.prevent

D.self

💡 Hint

Common Mistakes

Using .prevent only stops default action but not propagation.

Using .once only makes the event fire once, it does not stop bubbling.

The .stop modifier stops the event from bubbling up to parent elements.

3fill in blank

hard

Fix the error in the code to make the click event fire only once.

Vue

<button @click[1]="submit">Submit</button>

Drag options to blanks, or click blank then click option'

A.stop

B.prevent

C.once

D.capture

Attempts:

3 left

💡 Hint

Common Mistakes

Using .stop or .prevent does not limit the event to one time.

Forgetting to add any modifier causes the event to fire multiple times.

The .once modifier makes the event listener run only once and then remove itself.

4fill in blank

hard

Fill both blanks to prevent default and stop propagation on a link click.

Vue

<a href="#" @click[1][2]="handleClick">Link</a>

Drag options to blanks, or click blank then click option'

A.prevent

B.stop

C.once

D.capture

Attempts:

3 left

💡 Hint

Common Mistakes

Using only one modifier does not fully control the event.

Using .once does not prevent default or stop propagation.

Using .prevent stops the default link navigation, and .stop stops the event from bubbling up.

5fill in blank

hard

Fill all three blanks to create a button that fires once, prevents default, and stops propagation.

Vue

<button @click[1][2][3]="doAction">Action</button>

Drag options to blanks, or click blank then click option'

A.once

B.prevent

C.stop

D.capture

Attempts:

3 left

💡 Hint

Common Mistakes

Missing one or more modifiers causes incomplete event control.

Using .capture is unrelated to these behaviors.

The modifiers .once, .prevent, and .stop together make the event fire once, prevent default behavior, and stop bubbling.
