title: CodeIgniter dropdown (Javascript?)
body: <p>Is there any way I can make a dropdown submit a form without clicking a button to to submit it.  I want to be able to change languages on the fly in my site.  I have the languages all set up.  Here's my dropdown:</p>
  
  <pre><code>&lt;?php echo form_open('languages'); 
      $language = array(
                          'select' =&gt; 'Select Language',
                          'english' =&gt; 'English',
                          'spanish' =&gt; 'Espa&amp;ntilde;ol',
                          'german' =&gt; 'Deutsch',
                          'french' =&gt; 'Fran&amp;ccedil;ais'
                      );
  
      echo form_dropdown('language', $language);
      echo form_hidden('current_page', uri_string());
      echo form_submit('submit', $this-&gt;lang-&gt;line('header6'));
      echo form_close();
  ?&gt;
  </code></pre>
  
  <p>How do I get the form to work without the submit button?</p>
