jQuery實(shí)現(xiàn)鼠標(biāo)拖動(dòng)div改變位置、大小的操作

發(fā)布時(shí)間:2021-04-09 15:37:19 來源:億速云 閱讀:237 作者:啵贊 欄目:開發(fā)技術(shù)

本篇內(nèi)容主要講解“jQuery實(shí)現(xiàn)鼠標(biāo)拖動(dòng)div改變位置、大小的操作”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實(shí)用性強(qiáng)。下面就讓小編來帶大家學(xué)習(xí)“jQuery實(shí)現(xiàn)鼠標(biāo)拖動(dòng)div改變位置、大小的操作”吧!

       實(shí)現(xiàn)類似windows窗體的效果,在中間拖動(dòng)改變div位置,在邊緣拖動(dòng)改變div大小,鼠標(biāo)在相應(yīng)的位置改變成相應(yīng)的形狀
效果如圖: (截圖沒顯示鼠標(biāo))
