Help with my simple javascript/jquery

Question

I have an id #navigation li a and a class .menu-description . I want to change class from .menu-description to .menu-descriptionnew whenever user hovers on #navigation li a

My jquery so far:

<script>
$(document).ready(function() {
  $('#navigation li a').onmouseover(function() {

  //Check if element with class exists, if so change it to new
           if ($('div.menu-description').length != 0)
                $('div.menu-description').removeClass('menu-description').addClass('menu-descriptionnew');
           //Check if element with class 'menu-descriptionnew' exists, if so change it to 'menu-description'
           else if ($('div.menu-descriptionnew').length != 0)
                $('div.menu-descriptionnew').removeClass('menu-descriptionnew').addClass('menu-description');
                });
});
</script>

But it's not working. Any suggestions? Thanks!
