jQuery ancestors using jQuery objects

Question

I\'d like to check ancestry using two jQuery objects. They don\'t have IDs, and are only going to be available as jQuery objects (or DOM nodes if you called get()

Answer 1

One way would be to use the filter function

$('a').click(function() {
    $(this).parents().filter(function() {
       return this == someDiv[0];
    }).each(function() {
       alert('foo');
    })
}

I think you may also be able to get away with using jQuery.inArray

if ($.inArray( someDiv, $(this).parents() ) ) {
        alert('boo');
}
