* $scope
  * $scope.$watch
    * 监听程序变化
  * $scope.$apply
    * 监听数据变化，数据变化，会影响视图。
* angular.module
  * controller
  * run
* angularJs的过滤器
  * currency
  * number
  * lowercase/uppercase
  * json
  * limitTo
  * date
  * orderBy
  * filter

```javascript
//过滤器组合使用
m1.controller('Aaa',['$scope','$filter',function($scope,$filter){

    //$scope.name = '723894734.7489545';
    //$scope.name = 'hello';
    //$scope.name = {"name":"hello","age":"20"};
    //$scope.name = ['a','b','c'];
    $scope.name = '3748935795';

    /*$scope.name = [
        {color:"red",age:"20"},
        {color:"yellow",age:"30"},
        {color:"blue",age:"40"},
        {color:"green",age:"10"}
    ];*/

    //$scope.name = $filter('uppercase')('hello');
    //$scope.name = $filter('number')('236478234.3647348',1);
    //$scope.name = $filter('date')('236478234','hh');

    //$scope.name = 'hello';

    $scope.name = $filter('firstUpper')('hello');


}]);


//自定义过滤器
//

m1.filter('firstUpper',function(){
    return function(str,num){
        //console.log(num);
        return str.charAt(0).toUpperCase() + str.substring(1);
    }
});
```
