thanks help.

you need add handler on li, after remove attribute class li , add new class 

$('.menu-primary li').click(function(){        $('.menu-primary li').removeattr("class");        if($(this).attr("id")=="1"){           $(this).addclass("one");        }        if($(this).attr("id")=="2"){           $(this).addclass("two");        }        if($(this).attr("id")=="3"){           $(this).addclass("three");        }     });
