插入元素的方法&＃xff0c;注意的是&＃xff1a;
list为child的时候才能够插入到元素中
var newChild &＃61; document.createElement(&＃39;A&＃39;);
newChild.appendChild(document.createTextNode(&＃39;chorme&＃39;));
newChild.setAttribute(&＃39;href&＃39;, &＃39;http://www.baidu.com&＃39;);
var list &＃61;document.getElementById(&＃39;msie&＃39;);
list.insertBefore(newChild, list.lastChild);
var brChild &＃61; document.createElement(&＃39;BR&＃39;);
list.insertBefore(brChild, list.lastChild);This is my HTML page. <br>
