jsp彈出自定義對(duì)話(huà)框 js彈出選擇對(duì)話(huà)框

文章插圖
分析1.點(diǎn)擊彈出框，狀態(tài)框和遮擋層（背景變灰）就會(huì)顯示出來(lái) display：block；
2.點(diǎn)擊關(guān)閉按鈕，模態(tài)框和遮擋層就會(huì)隱藏起來(lái) display：none;
3.在頁(yè)面中拖拽的原理：鼠標(biāo)按下并且移動(dòng)，之后松開(kāi)鼠標(biāo)
4.觸發(fā)事件是鼠標(biāo)按下mousedown，鼠標(biāo)移動(dòng)mousemove，鼠標(biāo)松開(kāi)mouseup
5.推拽過(guò)程：鼠標(biāo)移動(dòng)過(guò)程中，獲得最新的值賦給模態(tài)框的left和top值，這樣模態(tài)框就可以跟著鼠標(biāo)走了
6.鼠標(biāo)按下出發(fā)的事件源是最上面一行，就是id為title
7.鼠標(biāo)的坐標(biāo)減去鼠標(biāo)在盒子內(nèi)的坐標(biāo)，才是真正模態(tài)框的位置
8.鼠標(biāo)按下，我們要得到鼠標(biāo)在盒子的坐標(biāo)
9.鼠標(biāo)移動(dòng)，就讓模態(tài)框的坐標(biāo)設(shè)置為：鼠標(biāo)坐標(biāo)減去盒子坐標(biāo)即可，注意移動(dòng)事件寫(xiě)到按下事件里面
10.鼠標(biāo)松開(kāi)，就是停止拖拽，就是可以讓鼠標(biāo)移動(dòng)事件解除
