js获取cookie的值

[molizuqiuba]

Response.Cookies["login"]["UserName"] = UName;
Response.Cookies["login"]["deptID"] = deptID;
Response.Cookies["login"]["deptName"] =Server.UrlEncode(deptName);
Response.Cookies["login"]["SessionID"] = SessionID;
Response.Cookies["login"]["UserRank"] = UserRank;

用js获取cookie中["UserName"]的值，求解

 function getCookie(objName){//获取指定名称的cookie的值
    var arrStr = document.cookie.split("; ");
    for(var i = 0;i < arrStr.length;i ++){
     var temp = arrStr[i].split("=");
     if(temp[0] == objName) return unescape(temp[1]);
    }
   }
