示例1: selectMisspellingAsync
static String selectMisspellingAsync(Frame* selectedFrame, DocumentMarker& marker)
{
VisibleSelection selection = selectedFrame->selection()->selection();
if (!selection.isCaretOrRange())
return String();
// Caret and range selections always return valid normalized ranges.
RefPtr<Range> selectionRange = selection.toNormalizedRange();
Vector<DocumentMarker*> markers = selectedFrame->document()->markers()->markersInRange(selectionRange.get(), DocumentMarker::Spelling | DocumentMarker::Grammar);
if (markers.size() != 1)
return String();

// Cloning a range fails only for invalid ranges.
