Get this method in the binding event after vue binding event

Passing parameters using $event (event itself)

<input v-model="checknames" @change="changecheckbox(item,$event)" style="float: right" type="checkbox" :value="index" >

changecheckbox(val,element) {
 ( );
 if( ){
  .....
 }
}

The method of obtaining this binding event after the above vue binding event is all the content I share with you. I hope you can give you a reference and I hope you support me more.
