[Ctrl A 全部选择提示：你可先修改部分代码，再按运行]

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)

}else

}
}
}
}
function recover()
{
clearselect();
