이 기사의 예에서는 Tokyo Mall 메뉴 모방, Win 마우스 오른쪽 버튼 클릭 메뉴 모방 및 JS에서 구현한 Taobao TAB 특수 효과 모방에 대해 설명합니다. 참고할 수 있도록 모든 사람과 공유하세요. 세부 내용은 다음과 같습니다.
실용적인 메뉴 통합 효과가 매우 좋습니다. 다단계 드롭다운 메뉴, 도쿄 몰을 모방한 풀아웃 메뉴, Windows를 모방한 마우스 오른쪽 버튼 클릭 메뉴, 타오바오를 모방한 탭 메뉴가 각각 있습니다. 코드는 연구와 수정을 용이하게 하는 풍부한 주석과 함께 제공됩니다.
런닝 효과 스크린샷은 다음과 같습니다.
온라인 데모 주소는 다음과 같습니다.
