この記事の例では、jQuery が段階的な表示効果を持つ文字のマルチレベル関係図を実装する方法を説明します。皆さんの参考に共有してください。詳細は以下の通りです。

これは、jQuery がフェードアウト効果を持つキャラクターのマルチレベル関係図を実装する方法のデモンストレーションです。 setQuestPose:function の n はオブジェクトの総数を表し、r は周囲を表し、i はオブジェクトの数を表します。、w は外側のオブジェクトの広帯域を表し、h は外側のオブジェクトを表します。テストの際は注意してください。右下隅にエラーがある場合は、ページを更新してください。

実行中のエフェクトのスクリーンショットは次のとおりです:

オンラインデモのアドレスは次のとおりです:

具体的なコードは次のとおりです:
