jquery event - getting the context

if I have :

$('.someClass', $('#context1,#context1')).bind('click',
    function(e){
    /开发者_如何学编程/ XXX
    }
);

how can I know in point XXX , which context (context1 or context2) is the one that the .someClass element was clicked ?

Thanks, greetings

This should work

$(this).parents().filter("#context1,#context2")

Edit: My previous example had find instead of filter, I've fixed it
