How to find a parent with a known class in jQuery?

Assuming that this is .d, you can write

$(this).closest('.a');

The closest method returns the innermost parent of your element that matches the selector.

javascript jquery html dom parent

Pass a selector to the jQuery parents function:

d.parents('.a').attr('id')

EDIT Hmm, actually Slaks's answer is superior if you only want the closest ancestor that matches your selector.

javascript jquery html dom parent

You can use parents() to get all parents with the given selector.

Description: Get the ancestors of each element in the current set of matched elements, optionally filtered by a selector.

But parent() will get just the first parent of the element.

Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.

And there is .parentsUntil() which I think will be the best.

Description: Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector.
