I am working with Vue.js 2.0 and attempting to send an event from a `child component`

I've been working with Vue.js 2.0 and I'm facing an issue trying to emit an event from a child component to the parent component, but unfortunately, it's not functioning as expected.

Here is a glimpse of my code:

child component:

<template>
  <button @click="confirmSendMessage">Send</button>
</template>

<script>
  export default {
    methods: {
      confirmSendMessage () {
        this.$emit('confirmed')
      }
    }
</script>

parent component:

<template>
    <ConfirmMessage/>
</template>

<script>
    import ConfirmMessage from './ConfirmMessage'
    export default {
        events: {
           confirmed() {
              console.log('confirmed')
           }
        },
        components: {
            ConfirmMessage
        }
   }
</script>

Upon clicking the button, no message appears in the Chrome console for me. I am perplexed by this situation and would greatly appreciate any assistance or guidance. As a beginner in Vue JS, I am seeking help to resolve this dilemma.

Answer №1

Make sure you are listening for the emitted event. Utilize v-on to catch the event:

<!--                               vv -> call method -->
<ConfirmMessage v-on:confirmed="confirmed" />
<!--                  ^^ -> emitted event -->

Answer №2

It is important to pay attention to the events being emitted. According to the Emit Documentation, the first argument expected is the name of the event as a string, followed by any values you wish to pass to the listener.

Therefore, the syntax should be as follows:

<confirm-message :nameOfEvent="functionToExecuteWhenTheEventIsEmitted" />

The corresponding method would look like this:

functionToExecuteWhenTeEventIsEmitted(someValue) { //do whatever with someValue}

And in the child component:

this.$emit('nameOfEvent', someValue)

In your specific case

Since you are not passing any values, using this.$emit('confirmed') and

<ConfirmMessage :confirmed="confirmed">
will suffice.
