权限系统设计与开发
什么是权限系统？
权限系统是一种设定用户与可操作模块之间关系的系统。
通过设定用户与可操作的模块之间的关系,控制用户在可指定范围内进行业务执行
基于用户的权限控制(UBAC:User-BasedAccessControl)
基于角色的权限控制(RBAC:role-BasedAccessControl)
角色的权限控制RBAC
树形控件结构分析（1）
树形结构如下图所示：
对应的实现技术有：
dTree
tdTree
zTree
我们主要来看关于zTree的相关操作.
我们主要是针对里面的Checkbox 勾选操作进行学习，我们自己来编写一个测试页面test.html来完成一个树形结构，操作步骤：
- 1.观察整体的页面结构
- 2.去除无效的基础信息
- 3.去除页面无效的基础信息
- 4.分析页面js内容
- 5.分页结构所使用的数据
- 6.简化页面内容书写

树形控件结构分析（2）
分析页面js
- 1.观察整体的页面结构
- 2.去除无效的基础信息
- 3.去除页面无效的基础信息
- 4.分析页面js内容
- 5.分页结构所使用的数据
- 6.简化页面内容书写
