jquery - find first previous node with certain properties

Question

regardless of parent/child-relations etc, how do I find the node closest above $(this) node with a certain property, for example class="field"?

Answer 1

This should do the trick (assuming .field is a parent of this):

$(this).closest(".field");

Answer 2

$(this).closest(".field");

Documentation: http://api.jquery.com/closest/

Answer 3

$(this).parents(".field:first")
