07..前后台交互,设计模式

1.前后台交互

2.设计模式

----------------------------------------------------

node server-run.js

前后端分离

本地存储

接口文档要会看

----------------------------------------------------

.on("click",function(){}) //可以绑定未来元素虚拟DOM

----------------------------------------------------

设计模式

1.工厂模式重复的产生N个实例
