jQuery | Traversing Ancestors

It is used to find ancestors of an element in the DOM tree. There are different Methods for traversing up the DOM tree :

parent(): It is used to return the direct parent element of the given selected element.
parents(): It is used to return all ancestor elements of the given selected element upto root element.
parentsUntil(): It is used to return all the ancestor elements between two given arguments.

Syntax:

$(document).ready(function(){
  $("span").parent().css({"color": " ", "border": " "});
});

Example-1: Showing parent() method.
