title: how to use liveValidation to validate a form on submit?
body: <p>I have the following code to validate the form on submit:</p>
  
  <pre><code>&lt;form enctype='multipart/form-data' 
     action='ad_posting_process.php' 
     method='post'&gt;
     Price: &lt;input type=text name=price 
                    id="price" style=width:90px;&gt;
  &lt;script type="text/javascript"&gt; 
    var f3 = new LiveValidation('price');
    f3.add( Validate.Numericality );
  &lt;/script&gt;
  Email: &lt;input type=text name=email 
                    id="email" style=width:240px;&gt;
  &lt;script type="text/javascript"&gt; 
    var f20 = new LiveValidation('email');
    f20.add( Validate.Email );
  &lt;/script&gt;
  &lt;script type="text/javascript"&gt;
    var title = new LiveValidation( 'title', {onlyOnSubmit: true } );
    title.add( Validate.Email );
    var field2 = new LiveValidation( 'price', {onlyOnSubmit: true } );
    field2.add( Validate.Acceptance );
    var field3 = new LiveValidation( 'email', {onlyOnSubmit: true } );
    field3.add( Validate.Presence );
  &lt;/script&gt;
  &lt;input type=submit name=action value=Post&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>the email validation is working, but how to validate the whole form on submit?</p>
  
  <p>Regards:</p>
