如我在左侧创建一个树形菜单：可以有如下几种方式：
1、利用<ul>和<li>创建静态的树：
在上篇文档创建的后台页面基础上添上：
<
ul
class
=
"easyui-tree"
>
<
li
>
<
span
>
Folder
</
span
>
<
ul
>
<
li
>
<
span
>
Sub Folder 1
</
span
>
<
ul
>
<
li
><
span
>
File 11
</
span
></
li
>
<
li
><
span
>
File 12
</
span
></
li
>
<
li
><
span
>
File 13
</
span
></
li
>
</
ul
>
</
li
>
<
li
><
span
>
File 2
</
span
></
li
>
<
li
><
span
>
File 3
</
span
></
li
>
</
ul
>
</
li
>
<
li
><
span
>
File21
</
span
></
li
>
</
ul
>
即homePage.jsp变为：
<%@
page
language
=
"java"
contentType
=
"text/html; charset=UTF-8"
pageEncoding
=
"UTF-8"
%>
<%@
include
file
=
"/common/head.jsp"
%>
<
html
>
<
head
>
<
title
>
