removeAllRanges method
void
removeAllRanges()
The Selection.removeAllRanges() method removes all ranges from the
selection, leaving the Selection.anchorNode and Selection.focusNode
properties equal to null and nothing selected. When this method is
called, a Document/selectionchange_event event is fired at the document.
Note: This method is an alias for the Selection.empty method.
Implementation
