좋은 사진 검색 효과_이미지 특수 효과 추천-JS 튜토리얼-php.cn

WPSXXX의 IMG에서 영감을 받은 것이 DIV보다 큽니다.
부족한 부분이 있으면 수정하거나 제안해 주시면 감사하겠습니다.

[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]

(不会封装代码有待更一步优化...)
关于层拖动第一次写参考了一些别人的方法直接在mousedown里加mousemove事件在mouseup里取消move事件写不来只能手动加在div上面加3个事件...

PS:貌似这素自从加入51js后第2个原创(也不知道别人写过没应该写过吧...) 记的没错的话和第一次写相隔了4年多了...-_-|||...看着代码能运行感觉真好早知道应该考计算机系的...
