how can we access elements of master page in content page using jquery

THANK YOU FOR YOUr ANSWER,

yes jquery is client side framework,,, u r right
i am trying to access li elements using jquery selector like
$('[id$=limnuDashboard]').click(function(){
alert("this is wokrin....");
});
this is not working...
this code is in default.aspx page...
and actually the li element with id limnuDashboard is in master page and master page is attached with....default.aspx...
we can access any elements from simple page one wich is without master page easily but its having problem to access elements of master page in content page....

hope i could explained actual situation correctly,,,




thanks,
IN ADVANCE...
