Question

By default the parent element is not visible. However, depending on what is clicked a child element may contain a class named “selected”. How do i test for this class and then if it exists make the whole list visible?

    <ul style="display: none;">
       <li class="selected">a</li>
       <li>b</li>
       <li>c</li>
    </ul>

if( $('li').hasClass('selected')){
    $('li.selected').parent().show();
}​
