DOM insertBefore() & DOM parentNode property
這兩個常一起搭配使用,
所以一起看,
insertBefore()定義:
inserts a node as a child, right before an existing child, which you specify.
另外, 很常用的一招: 當你希望在list中新增含有text node的node時,
code的做法流程為-->
If you want to create a new list item, with text, remember to create the text as a Text node which you append to the <li> element, then insert <li> to the list.
