Angularjs演示Service功能

var demoApp = angular.module('demoApp', []);

demoApp.service('calcService', function () {
    this.Addition = function (num1, num2) {
        return num1 + num2;
    }

    this.Substruction = function (num1, num2)
    {
        return num1 - num2;
    }

    this.Multiplication = function(num1, num2)
    {
        return num1 * num2;
    }

    this.Division = function (num1,num2)
    {
        return num1 / num2;
    }
});

demoApp.controller('demoController', function ($scope, calcService) {
    $scope.result1 = calcService.Addition(12, 4);
    $scope.result2 = calcService.Substruction(14, 3);
    $scope.result3 = calcService.Multiplication(7, 9);
    $scope.result4 = calcService.Division(15, 3);
});
