title: question about jQuery inline form validation
body: <p>Here is a link on   jQuery inline form validation that I'm trying to use
  <a href="http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/" rel="nofollow">http://www.position-absolute.com/articles/jquery-form-validator-because-form-validation-is-a-mess/</a></p>
  
  <p>Everything looks good but I have a small problem</p>
  
  <p>I have an input where I use this kind of validation</p>
  
  <pre><code>'validate[length[6,15]]'
  </code></pre>
  
  <p>It checks if number of length of input value and if it is less then 6 or grater then 15 gives and error.</p>
  
  <p>Now what I want is to add there chance for input to have value length=0 , so the validation won't fire any error message.</p>
  
  <p>Is that possible ?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>This is submit blocking function</p>
  
  <pre><code>&lt;script type='text/javascript'&gt;
    $(document).ready(function() {
  $('#standart_form').validationEngine();
   $('#standart_form').submit(function() {
    return false;
   });
   });
    &lt;/script&gt;
  </code></pre>
  
  <p>Now when I was using this <code>'validate[length[6,15]]'</code> everything was working good. But If I try using new custom functions the whole forms submits itself ruining my ajax based application. </p>
