title: How to use placeholder as default value in select2 framework
body: <p>To get the chosen value of a <code>select2</code> I'm using:</p>
  
  <pre><code>var x = $("#select").select2('data');
  var select_choice = x.text
  </code></pre>
  
  <p>The problem is this throws an error if not value has been selected and I was wondering if there was any way to make it return the placeholder if no option is selected</p>
