title: Creating one element on after();
body: <p>I'm using jquery. Is there any other way to limit of creating elements?</p>
  
  <p>here's my code..</p>
  
  <pre><code>if($(this).val() == "") {
     $(this).addClass('error').after('&lt;span class="jquery_form_error_message"&gt;' + 'This field is required' + "&lt;/span&gt;");
     validated = false;
     return false;
  </code></pre>
  
  <p>this is actually a validation .. you can't skip unless you field out every field data. 
  my problem is . when I click the submit . button.. it create a multiple span class on on the top of div.. which it's quite a mess.</p>
