vue.jsHow can I emit an event to a grandparent component in Vue.js?

To emit an event to a grandparent component in Vue.js, you can use the $emit method. The $emit method allows you to trigger an event from a child component and pass data to the grandparent component. Here's an example:

<template>
  <div>
    <grandparent-component>
      <parent-component>
        <child-component @emit-data="handleEmitData"/>
      </parent-component>
    </grandparent-component>
  </div>
</template>

<script>
export default {
  methods: {
    handleEmitData(data) {
      this.$emit('data-emitted', data);
    }
  }
}
</script>

The handleEmitData method in the example above is triggered when the emit-data event is emitted from the child component. The handleEmitData method then emits the data-emitted event with the data passed to it from the child component.

Code explanation

1. <grandparent-component> - This is the grandparent component.
2. <parent-component> - This is the parent component, which is nested inside the grandparent component.
3. <child-component @emit-data="handleEmitData"/> - This is the child component, which is nested inside the parent component. The @emit-data attribute is used to bind the emit-data event to the handleEmitData method.
4. handleEmitData(data) {...} - This is the handleEmitData method, which is triggered when the emit-data event is emitted from the child component.
5. this.$emit('data-emitted', data); - This is the $emit method, which is used to emit the data-emitted event with the data passed to it from the child component.
