extern class js.html.DOMSelectionAvailable in js

Selection is the class of the object returned by window.getSelection() and other methods. It represents the text selection in the greater page, possibly spanning multiple elements, when the user drags over static text and other parts of the page. For information about text selection in an individual text editing element, see Input , TextArea and document.activeElement which typically return the parent object returned from window.getSelection() .

A selection object represents the ranges that the user has selected. Typically, it holds only one range, accessed as follows:

var selObj = window.getSelection();
var range  = selObj.getRangeAt(0);
  • selObj is a Selection object
  • range is a Range object

Calling the Selection/toString() method returns the text contained in the selection, e.g

var selObj = window.getSelection();

Note that using a selection object as the argument to window.alert will call the object's toString method.

Documentation for this class was provided by MDN.
