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.
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);
}
})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));
}
})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')
}
})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
}
}
