jQuery - How to select the first parent of an element and add a new class "testclass"

Question

First Name

Given element 'element_1', how to select its first parent with tag name as li?

Thank you

Answer 1

$('#element_1').closest('li').addClass('testclass');

assuming you're using jQuery 1.3+ and element_1 is an ID.

jQuery < 1.3 should look like

$('#element_1').parents('li').addClass('testclass');

Reference: .closest(), .parents()

Answer 2

$('#element_1').closest('li').addClass('testclass');
