d3 forceレイアウトリンクの更新中に問題が発生しています。私はその関数の目的は、ノードの周りのすべてのリンクを強調表示することであるisChildofQuery(root.children, false);と呼ばれる機能を持って、このコードでD3 force layout：リンクの色を更新するには？

</html>：これは私のコードです。これは、グラフが最初に作成されたとき（選択されたノードの色がyelloで、周囲のすべてのリンクが赤色である場合）、完全に機能しています。しかし、選択されたノードが変更されているとき（上のオプション選択で）、新しいノードの色は正しく変更されますが、選択した周辺のリンクは正しくありません。誰かが私に何が喜んでいるかを知ってもらえるか？
