WordPress Menu apply Classes and Page Transition

Is it possible to apply a class to the anchor tag of a wordpress menu item and not to the list tags that surround the anchor tags?

because i am wanting to link the wordpress menu to this bit of code in order to create a page transition.

$(document).ready(function() {
$('body').css('display', 'none');
$('body').fadeIn(1000);

$('.trans').click(function() {
event.preventDefault();
newLocation = this.href;
$('body').fadeOut(500, newpage);
});
function newpage() {
window.location = newLocation;
}
});
