What are some advanced examples of using emit in Vue 3?

Can you explain how to use emit in Vue 3 with some advanced examples?

Sure! In Vue 3, the emit function is used to create custom events. For example, you can emit an event from a child component to notify the parent about a specific action.

Can you give me a specific example of emitting an event with parameters?

Absolutely! Let's say you have a button in a child component. You can emit an event like this: this.$emit('button-clicked', { id: 1, name: 'Sample' }); This sends an object with parameters to the parent.

How can I handle that emitted event in the parent component?

In the parent component, you can listen for the event using the v-on directive: <ChildComponent @button-clicked='handleButtonClick' />. Then, define the handleButtonClick method to process the received data.

What if I want to emit multiple events from the child?

You can emit multiple events by calling this.$emit multiple times for different actions. Just ensure each event has a unique name.
