I'm trying to write a form validation and I'm stuck with writing a selector for this select-option element without any other attribute.

<select multiple="multiple" name="formCountries[]">
How can I do this?
                possible duplicate of How do I get the selected element by name and then get the selected value from a dropdown using jQuery?

Try like this. See Attribute Selector
$('select[multiple = multiple][name="formCountries[]"]').change(function() {
You can use attribute selector to select by name. You have to escape the square brackets which could be done by wrapping the name in quotes.
Live Demo
var sel = $('[name="formCountries[]"]');
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
  <script>
   $(document).ready(function(){
     $('#btn').click(function(){
       alert('ding '+$('select').val());
  </script>
 </head>
  <input type="button" id="btn"/>
  <select multiple="multiple" name="formCountries[]">
   <option value="volvo">Volvo</option>
   <option value="saab">Saab</option>
   <option value="mercedes">Mercedes</option>
   <option value="audi">Audi</option>
  </select>
 </body>
</html>
