If the browser supports a Selection object or TextRange objects, you may then be able to access the selected text using JavaScript. Of course in a form object, the text of the whole object can also be accessed, but this may not be what was selected because the user may select all or part of a page and that selection may span several form elements or only part of a form element.

Unless you call this method, the bounded area of the TextRange object will not be visible to the user.
