示例1: updateFocusCandidateIfCloser
static void updateFocusCandidateIfCloser(Node* focusedNode, const FocusCandidate& candidate, FocusCandidate& closest)
{
// First, check the common case: neither candidate nor closest are
// inside scrollable content, then no need to care about enclosingScrollableBox
// heuristics or parent{Distance,Alignment}, but only distance and alignment.
if (!candidate.inScrollableContainer() && !closest.inScrollableContainer()) {
updateFocusCandidateInSameContainer(candidate, closest);
return;
}
bool sameContainer = candidate.document() == closest.document() && candidate.enclosingScrollableBox == closest.enclosingScrollableBox;
// Second, if candidate and closest are in the same "container" (i.e. {i}frame or any
// scrollable block element), we can handle them as common case.
if (sameContainer) {
updateFocusCandidateInSameContainer(candidate, closest);
return;
}
// Last, we are considering moving to a candidate located in a different enclosing
// scrollable box than closest.
bool isInInnerDocument = !isInRootDocument(focusedNode);
