Example
Use The Evaluator (Chapter 13 in the JavaScript Bible) to see the results of the
toString() method. Enter the following sequence of statements into the top
text box:
a = document.createRange()
a.selectNode(document.getElementById(“myP”))
a.toString()
If you type only a into the top text box, you see the text contents of the range,
but don’t be fooled. Internal workings of The Evaluator attempt to evaluate any
expression entered into that text field. Assigning a range object to a text box forces
an internal application of the toString() method (just as the Date object does
when you create a new object instance in The Evaluator).

Example
Listing 19-7 contains a page that demonstrates several features of the selection
object. When you make a selection with the Deselect radio button selected, you see
the value of the selection.type property (in the statusbar) before and after the
selection is deselected. After the selection goes away, the type property returns
None.
