angular.module('myApp',[],function ($filterProvider,$provide,$controllerProvider) {
    $provide.service('Data',function () {
        return [
            {
                name:'张三',age:20,city:'上海'
            },{
                name:'李四',age:30,city:'北京'
            }
        ]
    });
    //创建过滤器第一种方法
    $filterProvider.register('filterAge',function () {
        return function (obj) {
            var newObj = [];
            angular.forEach(obj,function (o) {
                if(o.age > 20){
                    newObj.push(o)
                }
            })
            return newObj;
        }
    });
    
    $controllerProvider.register('firstController',function ($scope,Data) {
        $scope.data = Data;
    })
    //创建过滤器第二种方法
}).filter('filterCity',function () {
    return function (obj) {
        var newObj = [];
        angular.forEach(obj,function (o) {
            if(o.city === '上海'){
                newObj.push(o)
            }
        })
        return newObj;
    }
})
