DOM Traversal Methods

DOM Traversal Methods
.parents()
Gets the ancestors of each element in the current set of matched elements,
optionally filtered by a selector.
.parents([selector])
Parameters
•
selector (optional): A string containing a selector expression to match
elements against
Return Value
The new jQuery object.
Description
Given a jQuery object that represents a set of DOM elements, the .parents method
allows us to search through the ancestors of these elements in the DOM tree and
construct a new jQuery object from the matching elements. The .parents() and
.parent() methods are similar, except that the latter only travels a single level up
the DOM tree.
The method optionally accepts a selector expression of the same type that we can
pass to the $() function. If the selector is supplied, the elements will be filtered by
testing whether they match the selector.
Consider a page with a basic nested list on it:
I
II
A
B
1
2
3
C
III
