<style>div{width:100px; height: 100px; position: relative; background: yellow;}span{width: 100px; height: 100px;position: absolute;top:-100px;left: 0;background: red;}</style><script></script><div> <span></span> </div>怎樣寫jQuery能讓鼠標(biāo)進(jìn)入div時(shí)，span勻速從上往下完全覆蓋，移開時(shí)能從當(dāng)前所到達(dá)的位置勻速從下往上
鼠標(biāo)進(jìn)入和離開
