Example
Use The Evaluator (Chapter 13 in the JavaScript Bible) to see how the duplicate()
method works. Begin by creating a new TextRange object that contains the text of the
myP paragraph element.
a = document.body.createTextRange()
a.moveToElementText(myP)
Next, clone the original range and preserve the copy in variable b:
b = a.duplicate()
The method returns no value, so don’t be alarmed by the “undefined” that appears
in the Results box. Move the original range so that it is an insertion point at the end
of the body by first expanding it to encompass the entire body, and then collapse it
to the end:
a.expand(“textedit”)
a.collapse(false)
