jquery traversing to find a parent's parent

Answer 1

.parent() by itself just refers to the immediate ancestor of a node, but you can also do:

var li = $('a.del').parents('li.comment');

to have JQuery go back up the DOM tree until it finds a matching ancestor node. In this case, li will point at the a's li ancestor.

edit: forgot that .parent() only goes up one level, while .parents() goes up the entire tree. Both accept a selector argument, however.
