    [基础] angular 过滤器介绍

    用法

    HTML

    {{ name | uppercase }}
    

    javascript

    app.controller('DemoController', ['$scope', '$filter',
        function($scope, $filter) {
            $scope.name = $filter('lowercase')('Ari');
        }
    ]);
    

    过滤器介绍:
    currency - 数值格式化为货币格式
    date - 将日期格式化成需要的格式
