通過原生JS，點擊事件，鼠標按下、鼠標抬起和鼠標移動事件，實現3d立方體的拖動旋轉，并將旋轉角度實時的反應至界面上顯示。
實現原理：通過獲取鼠標點擊屏幕時的坐標和鼠標移動時的坐標，來獲得鼠標在X軸、Y軸移動的距離，將距離實時賦值給transform屬性
從而通過改變transform：rotate屬性值來達到3d立方體旋轉的效果
HTML代碼塊：
<body><input type="button" class="open" value="點擊散開"/><input type="text" class="xNum" value=""/>//X軸旋轉角度<input type="text" class="yNum" value=""/>//Y軸旋轉角度<input type="text" class="zNum"/><div class="big_box"><div class="box"><span></span><span></span><span></span><span></span><span></span><span></span></div></div></body>
