title: Jquery check multiple Selects have value set
body: <p>I have a form with multiple select fields allowing you to select multiple entries per select.</p>
  
  <p>Each select is named <code>id1[]</code>, <code>id2[]</code>, <code>id3[]</code> etc.</p>
  
  <p>With Jquery when trying to submit the form can I check if any of the selects haven't had anything selected ?</p>
  
  <p>I've tried this, but the form still submits.</p>
  
  <pre><code>$("#submit").click(function() {
          $("select[name^='id']:visible").each(function(index, element) {
              if ($(this).val() == "") return false; 
          });
  });
  </code></pre>
  
  <p>I don't need to know which specific 'id' select hasn't had an option selected, but it would be nice if I did..</p>
  
  <p>Thanks</p>
