Vue 3, $emit never firing - vue.js

Question

The documentation is not enough to be able to do the emit. I have seen many tutorials and nothing works, now I am testing this
Child component
<div #click="$emit('sendjob', Job )"></div>
With the Vue DevTools plugin I can see that the data is sent in the PayLoad, but I can't find a way to receive this emit from the other component.
Many people do this
Any other component
<template>
<div #sendjob="doSomething"></div>
</template>
<script>
export default {
methods:{
doSomething(){
console.log('It works')
}
}
}
</script>
In my case it doesn't work

Answer 1

You should import the child component in the parent component and use it instead of the regular div tag.
I'm sharing examples for your reference to achieve emits in Vue 3 using <script setup> and Composition API. I strongly suggest going with <script setup if you are going to use Composition API in Single File Component. However, the choice is yours.
Example with <script setup>: https://v3.vuejs.org/api/sfc-script-setup.html
<!-- App.vue -->
<template>
<UserDetail #user-detail-submitted="userDetailSubmitted"/>
</template>
<script setup>
import UserDetail from './components/UserDetail';
function userDetailSubmitted(name) {
console.log({ name })
}
</script>
<!-- UserDetail.vue -->
<template>
<input type="text" v-model="name" #keyup.enter="$emit('user-detail-submitted', name)" />
</template>
<script setup>
import { ref } from 'vue';
const name = ref('');
</script>
Example using Composition API: https://v3.vuejs.org/api/composition-api.html
<!-- App.vue -->
<template>
<UserDetail #user-detail-submitted="userDetailSubmitted"/>
</template>
<script>
import UserDetail from "./components/UserDetail";
export default {
components: {
UserDetail,
},
setup() {
function userDetailSubmitted(name) {
console.log({ name });
}
return {
userDetailSubmitted
}
},
};
</script>
<!-- UserDetail.vue -->
<template>
<input type="text" v-model="name" #keyup.enter="$emit('user-detail-submitted', name)" />
</template>
<script>
import { ref } from 'vue';
export default {
setup() {
const name = ref('');
return {
name,
}
}
}
</script>

You should import this child-component in the parent. And don't rename it to the html's original tag.vue3. You'd better use the Composition API.
