In Vue.js, emit
is used to send custom events between components. Here is how you can use emit
in Vue.js:
1
|
this.$emit('event-name', eventData); |
Here, event-name
is the name of the event you want to emit, and eventData
is any data you want to pass along with the event.
1
|
<child-component v-on:event-name="handleEvent"></child-component> |
Here, event-name
should match the event name emitted in the child component, and handleEvent
is the method in the parent component that will be called when the event is emitted.
1 2 3 4 5 |
methods: { handleEvent(eventData) { // Handle the event here } } |
Here, eventData
is the data passed along with the event. You can access and use this data within the handleEvent
method.
By using emit
and custom events, you can establish communication between parent and child components, allowing them to exchange data and trigger actions based on user interactions or other events.
