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


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

交互例子 看看

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

 

设计模式

1.工厂模式 重复的产生N个实例
