Selection API

The Selection API enables developers to access and manipulate the portion of a document selected by the user.

The Window.getSelection() and Document.getSelection() methods return a Selection object representing the portion of the document selected by the user. A Selection object provides methods to:

• access the currently selected nodes
• modify the current selection, expanding or collapsing it or selecting an entirely different part of the document
• delete parts of the current selection from the DOM.

The Selection API also provides two events, both firing on Document:

• the selectstart event is fired when the user starts to make a new selection
• the selectionchange event is fired when the current selection changes.
