title: access data property vuejs2
body: <p>here is a piece of my code:</p>
  
  <pre><code>$(function () {
  
      var vm = new Vue({
          el: '#app',
          data: {
  
              myObject : {
                  id: "",
                  _class : "",
                  contentType : "TEXT",
                  textValue : "",
              },
              selected_language : "ENGLISH",
  
          }
  </code></pre>
  
  <p>I want to find a way to fill the <code>textValue</code> property with what is in <code>selected_language</code>.
  which mean that my object will look like:</p>
  
  <pre><code>myObject : {
                  id: "",
                  _class : "",
                  contentType : "TEXT",
                  textValue : "ENGLISH",
              }
  </code></pre>
  
  <p>Thanks for your help in advance, I am quite stuck</p>
