Usage
The $events
prototype object.
This plugin extends Vue.prototype
to include a new $events
object, which is a just a plain vm
that will serve as your global event bus. The $events
vm
has a couple aliases for the standard
event methods.
Firing an event
There are 3 methods that fire events.
Note: $events.fire
& $events.emit
are aliases for $events.$emit
new Vue({
data() {
return {
eventData: {
foo: 'baz'
}
}
},
mounted() {
this.$events.fire('testEvent', this.eventData);
this.$events.emit('testEvent', this.eventData);
this.$events.$emit('testEvent', this.eventData);
}
})
Listening for an event
There are 3 methods that register event listeners.
Note: $events.listen
& $events.on
are aliases for $events.$on
.
new Vue({
mounted() {
this.$events.listen('testEvent', eventData => console.log(eventData));
this.$events.on('testEvent', eventData => console.log(eventData));
this.$events.$on('testEvent', eventData => console.log(eventData));
}
})
Removing an event listener
There are 3 methods that remove event listeners.
Note: $events.off
& $events.remove
are aliases for $events.$off
.
new Vue({
mounted() {
this.$events.on('testEvent', eventData => console.log(eventData));
},
beforeDestroy() {
this.$events.$off('testEvent')
this.$events.off('testEvent')
this.$events.remove('testEvent')
}
})
The events
component options.
Provide an events
map as part of your component options and vue-events will automatically call $on when the component is mounted and $off when the component is destroyed.
new Vue({
events: {
testEvent(eventData){
console.log(eventData)
}
}
})
Inside the event handlers, this
is bound to the component instance. This way you can access your component's data, props, computed, methods, etc. For example:
new Vue({
events: {
onShowAlert(message){
this.modalVisible = true
this.message = message
}
}
})
