dTree对象本身没有定义这样的方法，不过应该可以用DOM方法来做：
//把下面两行代码加到document.write(d);这一行后面试试
var obj = document.getElementsByTagName('div')[0].getElementsByTagName('a');
for (var i = 0; i < obj.length; i ++) if (obj[i].className == 'node') obj[i].href = 'demo.html';
或者给这段代码每个叶子节点加链接，怎样实现？求高人指点啊！！<html><head><META http-equiv="Content-Type" content="text/html; charset=GB2312"><title>文档管理</title><SCRIPT LANGUAGE="JavaScript">
