var id;
function getid()
{
var url=location.search;
var Request = new Object();
if(url.indexOf("?")!=-1)
{
var str = url.substr(1) //去掉?号
strs = str.split("&");
for(var i=0;i<strs.length;i++)
{
Request[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
id=Request["id"];
document.getElementById(td_fa).innerHTML=id + "页面信息";
}
