title: Get value of a selected class vuejs
body: <p>I'm having a hard time trying to pass the value of a div with an active class. The user can select any tag and it toggleclass active. Only one tag can be active at a time.</p>
  
  <pre><code>&lt;div class="tag-box"&gt;
       &lt;div class="tag"&gt;Tag 1&lt;/div&gt;
       &lt;div class="tag active"&gt;Tag 2&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I would like to get the value who has the active class and return this value with axios like this</p>
  
  <pre><code>axios.post('http://localhost:4000/articles', {
     title: this.title,
     description: this.description
     tag: ????
   })
  </code></pre>
  
  <p>Since it is a not a HTML select tag, it is a bit more difficult to do it. 
  Is it possible to use an if statement inside a post request?</p>
  
  <p>Hope you can help me, thank you for your time! </p>
