javascript: how to reverse a range.execCommand method

Question

If I use the execCommand method to highlight the selected text:

document.execCommand("HiliteColor", false, colour);

as it is suggested in this page, and then I want to come back and cancel the highlight format (that is, to return to the situation as it was before I highlighted some text), what could I do?

Answer 1

The following will remove formatting:

document.execCommand("RemoveFormat", false, null);
