What are some in-depth examples of using emit in Vue?

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

Sure! In Vue, the emit method is used to send events from a child component to its parent. For example, if you have a button in a child component, you can emit an event when it's clicked.

Can you show me a specific code example?

Absolutely! Here's a simple example:

In the child component:

this.$emit('myEvent', data);

In the parent component:

<ChildComponent @myEvent="handleMyEvent" />

And in the methods of the parent:

methods: {
  handleMyEvent(data) {
    console.log(data);
  }
}

What if I want to pass multiple parameters?

You can pass multiple parameters by including them in an object. For example:

this.$emit('myEvent', { param1: value1, param2: value2 });

Then in the parent, you can access them like this:

handleMyEvent({ param1, param2 }) {
  console.log(param1, param2);
}
