children是Element的属性，childNodes是Node的属性

Node是Element的父类。

https://developer.mozilla.org/en-US/docs/Web/API/Element

Element的children[0]仍为Element，是Node和Element的实例，Node的childNdoes[0]为Node，只是Node的实例，不是Element的实例。

只要清楚操作对象是什么类型的实例就可以了，用什么都可以。参考博客：http://www.cnblogs.com/jscode/archive/2012/09/04/2670819.html
