javascript的namespace声明

function namespace(ns){
         var parent = window;
         var arNs = ns.split('.');
         do {
          var nowNs = arNs.shift();
          if (typeof parent[nowNs] != 'object') {
              parent[nowNs] = {};
          }
           parent = parent[nowNs];
         } while (arNs.length > 0)
       return eval("(" + ns + ")");
}
//example
namespace("ibm.app.user");
user.User = function(){}
user.Relation = {
}
