Using window.getSelection to get a string

Question

I'm trying to use window.getSelection to get a string but it's returning an object.

var text = '';
text = document.getSelection();
alert(typeof(text)); //object

Answer 1

.getSelection() returns a DOMSelection object. The DOMSelection class contains a .toString() method to turn it into a string.

So

var str = window.getSelection().toString();
alert(typeof(str));  // string.

Answer 2

getSelection returns a Selection object. You can get the selected text by calling its toString method.
