title: VueJS: Multiple components listening same event
body: <p>I have multiple components listening for the same event: Tabs are listening for events of its content.</p>
  
  <p>So in every Tab I have a <code>bus.$on('content::event', () =&gt; {})</code>.</p>
  
  <p>But my question is how to know which <code>Tab</code> component should act because of the event.</p>
  
  <p>An option would be pass the <code>tab_id</code> in the event and then in the Tab check if tab_id is equal to its id but I don't like this approach, it seems to be an unnecessary check.</p>
  
  <p>Any suggestion?</p>
