/*
  关于 getElementsByTagName('*') 和 all、 childNodes 和 children、 parentNode 和 parentElement、body 和 documentElement
  功能一样，但
  W3C的DOM模型中没有all对象，所以在Netscape 6.0 中放弃了对all的支持，因此必须用getElementsByTagName('*')来代替
  IE中坚持向前兼容，所以仍然支持，但getElementsByTagName('*')只有在ie 5.0以后支持
  同样W3C的DOM模型中也没有children、 parentElement对象，一些支持W3C的浏览器(firefox)，就不支持该对象，而支持parentNode、childNodes
