Can I get a Javascript event from the selection of text outside of text or textarea?

Sure, an example exists here: http://www.codetoad.com/javascript_get_selected_text.asp

Using what you see here, you could bind events to the click/release events of the document body, and check to see if there is a selection, and how long the selection is to determine if they've selected any text.

StackOverflow Archive:

  1. What's the event fired when a user selects text on a page?
  2. Javascript to get Paragraph of Selected Text in WebPage

You could capture the mouseUp event, and check if some text is selected using window.getSelection().

This method may however not be cross-browser compatible (the window.getSelection()).

EDIT: here is a pretty complete example with mouseUp binding : http://mark.koli.ch/2009/09/use-javascript-and-jquery-to-get-user-selected-text.html

This is not easy to do in a cross-browser way. In IE only the select event applies to body text as well as form inputs so would do what you want, but to detect when the user has made a selection in a cross-browser way you will need to handle both keyup and mouseup events. Even then you won't be detecting selection events such as the user using the "Select all" menu option (usually found in the Edit and right click context menus). So you're down to polling at regular intervals and checking properties of the selection object (obtained via window.getSelection() or document.selection in IE).
