Setting multiple choices using jquery chosen plugin

I'm using chosen's plugin to select multiple items from data loaded from a database. This is saved, and then I might want to load those choices again (the entire form, really) to edit it, and save changes.

I can successfully read the various choices from the select component like so:

$("#meet_participants").chosen().val();

However If I want to set the multiple choices I'm trying this test case:

HTML code:

<div class="row">
  <div class="form-group">
    <label class="control-label">Participantes</label><br>
    <b>
    <select data-placeholder="Ingrese los nombres" class="chosen-select form-control" style="width:60%" multiple id="meet_participants">
    <!--Filled with all db users.-->
    <option>hola</option>
    <option>mundo</option>
    <option>cruel</option>
    <option>como</option>
    <option>estas</option>
    </select>
    </b>
    <button class="btn btn-primary"><b>Tareas pendientes</b></button>
  </div> <!--formgroup-->
</div> <!--row-->

The after that I do (as per the example)

<!-- Bootstrap core JavaScript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="js/plugins/jquery-1.11.1.min.js"></script>
<script src="js/plugins/bootstrap.min.js"></script>  
<script src="js/plugins/chosen.jquery.js" type="text/javascript"></script>
<script type="text/javascript">
  var config = {
'.chosen-select'           : {},
'.chosen-select-deselect'  : {allow_single_deselect:true},
'.chosen-select-no-single' : {disable_search_threshold:10},
  }
  for (var selector in config) {
$(selector).chosen(config[selector]);
  }
</script>


<script>
  fillMemoForm();
  $("#meet_participants").chosen().val(["hola", "mundo", "cruel"]);
</script>

Only the last line is important, however I pasted everything just in case. As I understand this should have set the selected values to these three items, but it didn't. What am I doing wrong?

If you are getting comma separated value to be updated in chosen multiple select, first convert it into an array then trigger the update for that array.

var meet_participants = "hola,mundo,cruel";  
var array = meet_participants.split(',');
$('#meet_participants').val(array).trigger('chosen:updated');

Voilà !

A better solution for this instead of destroying and re-creating dom element would be 

$('#meet_participants').val(["hola","mundo","cruel"]).trigger('chosen:updated');

Val in chosen plugin does not refresh the control. Call destroy, like this instead

$('#meet_participants').chosen('destroy').val(["hola","mundo","cruel"]).chosen();


$('#meet_participants').chosen();

$('#btn1').click(function() {
  $('#meet_participants').chosen('destroy').val(["hola", "mundo", "cruel"]).chosen();
});

$('#btn2').click(function() {
  $('#meet_participants').chosen('destroy').val(["estas", "como"]).chosen();
});
body {
  padding: .5rem;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://harvesthq.github.io/chosen/chosen.jquery.js"></script>

<link href="http://harvesthq.github.io/chosen/chosen.css" rel="stylesheet" />

<form role="form">
  <div class="form-group">
    <select data-placeholder="Ingrese los nombres" class="chosen-select form-control" multiple id="meet_participants" style="width:50%">
      <option>hola</option>
      <option>mundo</option>
      <option>cruel</option>
      <option>como</option>
      <option>estas</option>
    </select>
  </div>

  <div class="form-group">
    <button id="btn1" class="btn">set ["hola", "mundo", "cruel"]</button>
  </div>
  <div class="form-group">
    <button id="btn2" class="btn">set ["estas", "como"]</button>
  </div>

</form>
