JS对象的深度克隆方法示例

function deepClone(obj)
{
  var o,i,j,k;
  if(typeof(obj)!="object" || obj===null)return obj;
  if(obj instanceof(Array))
  {
    o=[];
    i=0;j=obj.length;
    for(;i<j;i++)
    {
      if(typeof(obj[i])=="object" && obj[i]!=null)
      {
        o[i]=arguments.callee(obj[i]);
      }
      else
      {
        o[i]=obj[i];
      }
    }
  }
  else
  {
    o={};
    for(i in obj)
    {
      if(typeof(obj[i])=="object" && obj[i]!=null)
      {
        o[i]=arguments.callee(obj[i]);
      }
      else
      {
        o[i]=obj[i];
      }
    }
  }
  return o;
}
