HTML DOM Navigation
The DOM provides a hierarchical representation of the HTML document, where each element is considered a node in the tree. DOM Navigation allows you to move between these nodes, targeting specific elements or collections of elements based on their relationships within the tree.
1. Traverse between parent and child elements:
parentNode & Element
Access the direct parent of an element.
childNodes & children
Access the child nodes or elements of an element.
firstChild & lastChild
Access the first and last child nodes of an element.
2.Traverse between sibling elements:
Next & Previous Sibling
Access the next and previous sibling nodes.
Next & Previous ElementSibling
Access the next and previous sibling elements.
3. Search for specific elements:
querySelector() & SelectorAll()
Retrieve elements using CSS selectors.
getElementById(), ClassName(), & TagName()
Retrieve elements based on their ID, class name, or tag name.
By utilizing these navigation methods and properties, you can dynamically locate and manipulate elements within the DOM tree, enabling dynamic content updates, event handling, and interaction with the HTML document structure.
