extjs6 基础组件扩展和自定义组件封装--03全局方法、变量介绍

最先讲解全局方法，因为在后续的讲解中会常用。

Config.js  ：  全局变量 cfg  ,系统的基础配置变量  systemname（系统名称） 、sub（登录人员信息）、language(语言)、theme（主题风格）、crossdomain（是否跨域）。

CommonUtils.js   ： 全局变量 CU，js中辅组类，主要方法有getUUID 、 getBoolean、getRandomColor、getDate、getBeforeDateString 。

Loader.js  ：全局变量 Loader，JS、CSS加载器 ，使用 Loader.request(url); 即可加载需要的js或css。

localStorage.js ：全局变量 local，项目永久存储信息服务类。 因为 localStorage只能存储字符串。此类把对象转字符串存储和根据key取数据为对象。

sessionStorage.js ：  全局变量 session，项目临时存储信息,浏览器关闭自动清除。使用方式，session.get(key); session.set(key,object);

ExtUtils.js ：  全局变量 EU ，ext服务类，主要方法：redirectTo（全局路由） 、toastInfo（系统提醒）、RS(数据交互ajax、jsonp)、RSView（试图读取，包含缓存机制）

ProjectUtils.js ：全局变量 PU ，框架服务类，主要方法：openTabModule(在框架中tabPanel增加tab页签)、openModule（系统弹出窗口）、openAttachWindow（附件上传/下载组件）  download（文件下载）

全局变量

Ext.Panel                    主窗口ViewController对象

Ext.Viewport                    主窗口ViewporExt.FramePanel              

Ext.FramePanel            业务Panel面板

Ext.lockPanel                 锁屏Panel面板

Ext.SystemTabPanel           当前业务Panel面板中TabPanel对象

Ext.SystemTabPanelAutoOpens  当前业务Panel面板中TabPanel对象自动打开菜单窗口Map对象{menuid:obj}  //系统菜单加载时候提取数据

Ext.SystemFavorites          我的收藏菜单Map对象{menuid:obj}   //系统菜单加载时候提取数据

Ext.SystemLimits        我的界面权限Map对象  //执行PU.openTabModule时候创建新的tab，判断当前界面modelurl在SystemLimits是否存在，如果没有且加载并且保存在SystemLimits中
