Expansion of hitareas for links

gistfile1.js

$('.hitarea-container').each(function(){
    $(this).click(function(){
      $target = $(this).find('a.hitarea-source').first().attr('href');
      if ($target) window.location.href = $target;     
    });
});

// Relies on container to become 'clickable' having a class 
// of 'hitarea-container' and the link that should be the 
// target needs to be the href of the first link within that 
// element with the class 'hitarea-source'.
