已经封装成 js 文件的代码：
// javascript Document function preset() { document.getElementById("itemlist").childNodes[selectindex].firstChild.firstChild.className="style1"; document.getElementById("itemlist").childNodes[selectindex+1].childNodes[0].childNodes[0].className="style2"; innersubclass(); } function focusthis(obj) { clearselect(); obj.className = "style1"; obj.parentNode.parentNode.nextSibling.firstChild.firstChild.className="style2"; innersubclass(obj); } function innersubclass(obj) { if (obj==null) { document.getElementById("subclass").innerHTML = subclass[selectindex]; }else { for(i=0; i { if(obj == document.getElementById("itemlist").childNodes[i].firstChild.firstChild) { document.getElementById("subclass").innerHTML = subclass[i]; } } } } function recover() { clearselect(); preset(); innersubclass(); } function clearselect() { for (i=0; i { document.getElementById("itemlist").childNodes[i].firstChild.firstChild.className="style0"; } }
在代码编写过程中，发现 Firefox 对 DOM 解释和 IE 对 DOM 的解释差别较大。虽然上面的代码也兼容ff，但实现的方法不太标准，近期需要补习一下 FF 下的DOM。
目前此效果仅能应用于网站导航条，如果要做成斜体的选项卡效果，还需要调整一下代码，但估计不用重写了，呵呵
