Get the highlighted text within an iframe with Firefox 3.5

[DL]

I thought document.getElementById
('frameID').contentWindow.document.selection.createRange().text
should do it. However, it no longer works. What's the correct
syntax?

Thanks.

I thought document.getElementById
('frameID').contentWindow.document.selection.createRange().text
should do it.

This could be shortened to the more standards-compliant

document.getElementById('frameID').contentDocument.selection.createRange().text

For it to work in Gecko-based browsers, though, it always needed to be

document.getElementById('frameID').contentDocument.getSelection()

which returns the selected text (for highlighted images: the alternative
text) as a string value, or

document.getElementById('frameID').contentWindow.getSelection()

or the more standards-compliant

document.getElementById('frameID').contentDocument.defaultView.getSelection()

which both return a proprietary Selection object.

Recently also supported is the following feature specified in W3C DOM Level
2 Range:

document.getElementById('frameID').contentDocument.createRange().toString()

However, it no longer works.

Your approach has never worked in Firefox as neither the Gecko DOM nor the
W3C DOM support a `selection' property on Document objects; it is MSHTML-
proprietary.

Do not forget to put your question in the message body next time.

Beautiful (it works). Thank you.
