1. MVC mode:

Model: Data, in fact, is the angular variable ($scope. XX, $rootScope. xx);

View: Data rendering, html+directive (instruction);

Controller: Operation data, is function, data deletion and modification;

2, two-way binding:

Direction one: Model--->view

{model Data}} or <xxx ng-xxx= "model data" > Model change view to change;

Direction two: View--->model

< form control Ng-model= "model data Name" > View change model followed by change;

3. Dependency Injection:

Dependency Injection (Dependency injection, short di) is a design pattern, meaning that an object relies on other objects without manual creation, only need to "Roar a voice", when this object is created, its dependent objects are automatically created by the framework and injected into, in fact, is the least knowledge rule; All service and Provider objects in the module can implement DI based on the parameter name.

4. Modular Design:

Cohesion the principle of low coupling,

1) officially supplied modules Ng, Ngroute, Nganimate, Ngtouch

2) User-definable module angular.module (' Module name ', [])
