*		  _$m.moveDivDown('DivId', event);  运行点下鼠标事件，并传入此事件。DivId为类变量赋值，值为你要拖动的 div 层的 id 名也可传入对象。
*		  e.g _$m.moveDivDown(this, event);
*		  注：position:absolute;图层绝对定位
*	二、图层拖动类各属性方法说明：
*		属性：
*		moveDivId                          要拖动的图层 id。默认空
*		moveDivLeft                        图层原始居左距离。默认0
*		moveDivTop                         图层原始居上距离。默认0
*		onMouseDownState                   鼠标是否按下，按下为 true ，抬起为 false。默认 false
*		方法：
*		void moveDivInit()                 初始化属性值
*		void moveDivDown(event ev)         鼠标按下后的初始化
*		void moveDivUp()                   鼠标抬起后还原变量
*		void moveDiv(event ev)             鼠标移动控制图层位置
