I have the following jQuery code:

$('.show-additional-link').click(function(){
    $(this).parent().next().slideDown();
    $(this).hide();
    return false;
});

HTML:

<div class="row">
    <label for="native_language">Select</label>
    <select name="native_language" id="native_language">
      <option value="">Any</option>
      <option value="1">English</option>
    </select>

    <a class="show-additional-link" href="#">Select Additional Languages</a>
</div>

<div id="additional-languages" style="display: none;">
    <a class="hide-additional-link" href="#">[hide]</a>

    <div class="row">
        <!-- additional language checkboxes -->
    </div>
</div>

I would like to move the contents of my jQuery code (within the 'click' function) in to a separate function, as I will need to call it again on page load (after the form is submitted, so that the DIV is shown again automatically).

I'm having trouble with this - can anyone help?
