This project was generated with Angular CLI version 1.0.6.

最近业余学习 Angular，加入了两个 QQ 技术群。有位兄弟在群里最近一直吵吵着 省市区三级联动 的开发问题。我看他吵吵了差不多一个礼拜，还在吵吵。我就想，这个究竟有多难？刚好，我准备尝试下使用 github 看看，就花了半天时间，创建了这个项目。十几年的 C 开发经历之后，第一个开源项目居然是 TypeScript 项目，想想也是挺有意思的。

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|module.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.

Run ng test to execute the unit tests via Karma.

Run ng e2e to execute the end-to-end tests via Protractor. Before running the tests make sure you are serving the app via ng serve.

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
