javascript和jsp结合的问题

Question

就用<%%>啦，jsp就是干这个事的，二重循环也可以啊，

Answer 1

var leaf1 = new leaf("前言","#"); 
var leaf2 = new leaf("绪论","#"); 
branch1.add(leaf1); 
branch1.add(leaf2); 
myTree.add(branch1); 
var branch2 = new branch("branch2","第一章"); 
branch2.add(new leaf("第一节","#")); 
branch2.add(new leaf("第二节","#")); 
branch2.add(new leaf("第三节","#")); 
branch1.add(branch2); 
var branch3 = new branch("branch2","第二章"); 
branch3.add(new leaf("第一节","#")); 
branch3.add(new leaf("第二节","#")); 
branch3.add(new leaf("第三节","#")); 
branch1.add(branch3); 
myTree.add(new leaf("联系我们","#")); 
这部分从数据库读出
直接写

Answer 3

branch2.add(new leaf("第三节","#"));  branch2.add(new leaf("<%=rs.getString("ddd")%>","#")); 看了这个sample应该知道了八
