关于webbrowser的问题，请高手帮忙啊！

我用webbrowser打开了一个网页，怎么能够读取javascript里面相关的变量。
具体点说，网页上有两个frame，其中一个存放的是flash，一个是点击flash后显示的相关值

这个flash有49个格，每个格子都是有一些数据信息的，每次点击1个，就显示其中一个的数据信息

我找到了网页上相关的一段代码，附上，请高手帮忙解决，谢谢。

可能说的不是很清楚，不知道能否明白我说的意思，我主要想得到
obj.CAnsGetWorldMap.astGrid[24].iGridID 这个值，呵呵！

function ShowMaps(str)
{var obj=eval("("+str+")");
if(typeof(obj.CResult)!="undefined")
{msgbox("\u663e\u793a\u5730\u56fe\u5931\u8d25\uff1a"+errMsg(obj.CResult.iResultID)+"!");
return false}
tempMapstr="";

for(i=0;i<49;i++)

doShowGrid(obj.CAnsGetWorldMap.astGrid[dearr[i]],dearr[i],x)}
z=0;
for(b=0;b<49;b++)
{try{if(typeof($("map_bgmask"+b).height)=="number")z=b}
catch(x){}}
