To read the last event in Vue.js, you can use the $emit method to emit the event whenever it occurs, and then create a listener for that event in the component where you want to read the last event.


Here is a simple example:


In the component where the event occurs:

1
2
3
4
5
6
methods: {
  doSomething() {
    // do something
    this.$emit('myEvent', 'data');
  }
}


In the component where you want to read the last event:

1
2
3
4
5
6
created() {
  this.$root.$on('myEvent', eventData => {
    // eventData contains the data passed from the event
    console.log('Last event data:', eventData);
  });
}


By emitting the event with the $emit method and listening for it using $on, you can read the last event data in Vue.js.
