Check if option is selected with jQuery, if not select a default

by

While I’m not sure about exactly what you want to accomplish, this bit of code worked for me.

<select id="mySelect" multiple="multiple">
  <option value="1">First</option>
  <option value="2">Second</option>
  <option value="3">Third</option>
  <option value="4">Fourth</option>
</select>

<script type="text/javascript"> 
$(document).ready(function() {
  if (!$("#mySelect option:selected").length) {
    $("#mySelect option[value="3"]").attr('selected', 'selected');
  }
});
</script>
