var company = {};
company.name= '华为';
company.address = '北京';
company.produce = function(message)
{
 alert(message);
}

company= new Object();
company.name= '淘宝';
company.address = '杭州';
company.produce= function(message)
{
 alert(message);
}

company = function()
{
  this.name = '新浪';
  this.address = '北京';
  this.produce = function(message)
  {
  alert(message);
  }

window.name = '腾讯';
window.address = '北京';
window.produce = function(message)
{
  alert(message);
}

emptyObject = new Object();
company.apply = function(o, c,)
{
  if(o && c && typeof c == 'object')
  {
  for(var p in c)
  {
  o[p] = c[p];
  }
  }
  return o;
};
emptyObject = Ext.apply(emptyObject,company);

var copyOO = new Function();
copyOO.prototype = company;
var newcopyOO = new copyOO();
