/*
*表示必须,非必须项的第一个选项选项为默认选项
url(*)						Flash地址
id(*)						对联的ID，保持唯一，建议用nad+合同号+位置的形式，如：nad5694HomeLeft
width:90/任意数字			宽度
height:450/任意数字			高度
x:left/right				水平位置
xPx:0/任意数字				水平方向上Logo左边(右边)到浏览窗口左边（右边）的像素值
yPx:110/任意数字			垂直方向上Logo顶边(底边)到浏览窗口顶边（底边）的像素值
operaShow:true/false		因为Opera目前不支持as和js通信，可以Opera下对联无法关闭，可以通过false来设置Opera下对联不显示
