jQuery Traversing

This lesson is part of jQuery · All levels

Summary

Traversing is a technique of moving from one element to another element in a DOM tree structure, for example to a parent, descendant, or sibling. jQuery provides special methods such as parent(), children(), and next() so you don't need to write manual repetitions. With traversing, the selection can be expanded or narrowed from the element you're holding.

Key points

Main relationships: parent, descendant, and sibling
The traversing method returns the jQuery object so that it can be chained
The initial selection can be expanded as to parents() or narrowed as to first()
Traversing saves long and fragile selector writing
