function request(paras){

var url = locationhref;

var paraString = urlsubstring(urlindexOf("?")+urllength)split("&");

var paraObj = {}

for (i=; j=paraString[i]; i++){

paraObj[jsubstring(jindexOf("="))toLowerCase()] = jsubstring(jindexOf("=")+jlength);

}

var returnValue = paraObj[parastoLowerCase()];

if(typeof(returnValue)=="undefined"){

return "";

}else{

return returnValue;

//如你给出的地址可以这样

var classid = request("classid");
