title: Setting content into multiple TinyMCE textarea?
body: <p>I have 3 tinymce textarea, in my page. And I want to populate these text areas from ajax.</p>
  
  <p>I know the name of the original <code>textarea</code> field, but </p>
  
  <pre><code>tinyMCE.activeEditor.setContent(value);
  </code></pre>
  
  <p>does not work, since I dont have any active editor.</p>
  
  <p>Here is a basic example of my code</p>
  
  <pre><code>.
  .
  .
  function(data) {
  $.each(data, function(key,value)) {
      $("#"+key).val(value); //"#"+key is the id of tinymce editors in my form
  },
  "json"
  .
  .
  .
  .
  </code></pre>
