参数：id 弹出窗口id；

title：弹出窗口标题名称；

width：弹出窗口宽度

height：弹出窗口高度

content：弹出窗口显示内容

2、接口说明： closeDivWindow(id) 关闭窗口

参数： id 弹出窗口id

3、接口说明：setPopupTopTitleFontColor(PopupTopTitleFontColor) 设置弹出窗口标题字体颜色

参数：

4、接口说明：setPopupTopBgColor(tBgColor) 设置弹出窗口标题背景颜色

5、接口说明：

setPopupColor(borderColor,bgColor,tFontColor,cBgColor,fColor) 设置弹出窗口风格,包括标题栏的背景，弹出窗口边框颜色，内容窗体背景颜色，内容窗体字体颜色
