【转】jquery获取页面跳转的传值

function request(paras){  
    var url = location.href;   
    var paraString = url.substring(url.indexOf("?")+1,url.length).split("&");   
    var paraObj = {}   
    for (i=0; j=paraString[i]; i++){   
        paraObj[j.substring(0,j.indexOf("=")).toLowerCase()] = j.substring(j.indexOf("=")+1,j.length);   
    }   
    var returnValue = paraObj[paras.toLowerCase()];   
        if(typeof(returnValue)=="undefined"){   
        return "";   
    }else{   
        return returnValue;  
    }
}
//如你给出的地址可以这样
var classid = request("classid");
var id = request("id");
