1.改变this指针:call apply bind

2.响应式布局和屏幕自适应的区别:响应式会改变样式,自适应不会

3.什么是mvc?

　　组织代码结构的方式.本质是降低代码的耦合度

4.什么是什么?代码构建工具

参考网站:http://www.ydcss.com/archives/18

5.app开发有几种:混合开发,原生开发,webapp

6.ionic&reactN环境搭建:

　　1.AndroidDevTools Android SDK下载:http://www.androiddevtools.cn/

　　2.开源镜像站:http://mirrors.neusoft.edu.cn/

　　3.配置android环境变量

　　4.全局下载打包工具cordova和框架ionic

     5.创建ionic start 项目名

　　6.添加项目平台:ionic platform adb android 

　　7.直接运行在手机:ionic run android

 报错:no platforms added to this project.....

　　解决方案:进入项目文件夹,在命令行输入

1. cordova/ionic platform add android/ios,然后再执行上面第7条.
