jsp 和 html 怎么实现树型目录结构

%@ page language=”java” import=”java.util.*” pageEncoding=”UTF-8″%

String path = request.getContextPath();

String basePath = request.getScheme()+”://”+request.getServerName()+”:”+request.getServerPort()+path+”/”;

link rel=”stylesheet” type=”text/css” href=”styles.css”

body{font-size:13px;

line-height:20px;

}

a{font-size: 13px;

text-decoration: none;

}

a:hover{font-size:13px;

}

.no_circle{list-style-type:none; /*设置列表项标志的类型为无*/

display:none;

}

/style

script type=”text/javascript”

function show(){

if(document.getElementById(“a”).style.display==’block’){

document.getElementById(“a”).style.display=’none’; //触动的ul如果处于显示状态，即隐藏

}

else{

document.getElementById(“a”).style.display=’block’; //触动的ul如果处于隐藏状态，即显示

}

}

/script

/head

jsp目录树

不大明白你什么意思，是在Tomcat中显示网站目录结构？那么就在Tomcat的conf文件夹下找到web.xml文件，然后找到

servlet

servlet-namedefault/servlet-name

servlet-classorg.apache.catalina.servlets.DefaultServlet/servlet-class

init-param

param-namedebug/param-name

param-value0/param-value

/init-param

init-param

param-namelistings/param-name

param-valuefalse/param-value

/init-param

load-on-startup1/load-on-startup

/servlet

把 param-namelistings/param-name的下一行改为

param-valuetrue/param-value就可以了

用jsp 怎么设计 树形目录啊

const

maxn=50;

maxm=1024;

var

block: array[1..maxn]of longint;

sumblock: array[0..maxm]of longint;

box: array[1..maxn]of longint;

sumbox: array[0..maxn]of longint;

use: array[1..maxm+1]of boolean;

n ,m ,mid ,sum ,ans: longint;

ok: boolean;

procedure qs(l ,r: longint);

var

i ,j ,x ,t: longint;

begin

i:=l;j:=r;x:=block[(l+r) shr 1];

repeat

while block[i]x do inc(i);

while block[j]x do dec(j);

if i=j then begin

t:=block[i];block[i]:=block[j];block[j]:=t;

inc(i);dec(j);

end;

until ij;

if ir then qs(i,r);

if lj then qs(l,j);

end;

procedure init;

var

i: longint;

begin

readln(n);

fillchar(box,sizeof(box),0);

fillchar(sumbox,sizeof(sumbox),0);

for i:= 1 to n do begin

readln(box[i]);

sumbox[i]:=sumbox[i-1]+box[i];

end;

readln(m);

fillchar(block,sizeof(block),0);

fillchar(sumblock,sizeof(sumblock),0);

for i:= 1 to m do

readln(block[i]);

qs(1,m);

for i:= 1 to m do

sumblock[i]:=sumblock[i-1]+block[i];

end;

procedure find(now ,num ,V: longint);

var

j: longint;

begin

if now=mid+1 then begin

ok:=true;

exit;

end;

if sumbox[n]-sumbox[num]+Vsum then

exit;

for j:= mid downto 1 do begin

if use[j] then begin

if (use[j+1])and(block[j]=block[j+1]) then

continue;

if V=block[j] then begin

dec(sum,block[j]);

use[j]:=false;

find(now+1,num,V-block[j]);

if ok then exit;

inc(sum,block[j]);

use[j]:=true;

end;

end;

end;

if numn then

find(now,num+1,box[num+1]);

end;

procedure main;

var

find(1,1,box[1]);

if ok then begin

l:=mid+1;

ans:=mid;

end

else

r:=mid;

until (lr)or(l=mid);

end;

procedure ou;

begin

writeln(ans);

end;

end.

JSP网页中中那种目录树是怎么实现的？

用dtree很方便，我最近也是做这种目录树

JS创建

var tree = new dTree(‘tree’);

tree.add(10,0,’空间信息管理’,’goto(10)’,”,’_c’);

tree.add(11,10,’翠苑1区’,’goto(2)’,’单击查看该群组的信息’,’k’);

tree.add(12,10,’翠苑2区’,’goto(2)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(13,12,’第1栋’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(19,13,’第1单元’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(14,19,’第1层’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(15,14,’1号房’,’goto(1)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(17,11,’第1栋’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(18,11,’第2栋’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(20,17,’第1单元’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(21,17,’第2单元’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(22,18,’第1单元’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(23,18,’第2单元’,’goto(3)’,’单击查看该群组的信息’,’FRAME_LIST’);

tree.add(16,10,’嘉绿名苑’,’goto(2)’,’单击查看该群组的信息’,’FRAME_LIST’);

然后在需要的位置这样调用script type=”text/javascript”document.write(tree);/script

用jsp做树形目录怎么做

我刚刚做了这样一个东西，支持不定级的树。首先读取数据，之后在内存中生成树的结构，再用HTML形式(如果要实现用点击展开或收回的效果，加点JavaScript)表示出来，即可。
