在sb.append中怎么编写dtree.add语句

Btree bt=new Btree();
Iterator<TreeBean> treeIt=bt.getNodeInfo().iterator();
StringBuffer sb=new StringBuffer();
sb.append("dtree=new dTree(\"dtree\");");
while(treeIt.hasNext()){
TreeBean tr=treeIt.next();
sb.append("dtree.add("+tr.getID()+","+tr.getPid()+",\""+tr.getCname()+"\");");
}
sb.append("document.write(dtree);");
%>
</body>
<script type="text/javascript">
eval('<%=sb.toString()%>');
</script>
<script type="text/javascript">
a.TreeNodeOnClick = function(node) {
alert(node.id);
}
</script>
</html>
如果想在上面dtree.add方法添加一个url属性并传节点ID的话，整条语句应该怎么写？
