Join Joe Marini for an in-depth discussion in this video Traversing documents with jQuery, part of jQuery Essential Training.
- If you've done any serious web development,…you're probably familiar by now with the concept…that HTML pages are organized as a tree structure.…The relationships between elements in the page…within this tree structure…can be described using family-like terms.…For example, the HTML tag…is said to be at the root of the document tree,…and is the parent of the head and body tags.…In turn, the head and body tags…are also said to be children of the HTML tag…and siblings of each other.…This tree structure…and the relationships between the elements…are described using a standard API…called the Document Object Model, or DOM,…which is a W3C standard.…
