AngularJS -利用服务/控制器模型为所有客户端创建全局计时器

angular.module('myApp', [])
  .service('timerService', function() {
    var timer;

    this.startTimer = function() {
      timer = setInterval(function() {
        // 计时器逻辑
      }, 1000);
    };

    this.stopTimer = function() {
      clearInterval(timer);
    };

    this.resetTimer = function() {
      // 重置计时器
    };
  })
  .controller('myController', function($scope, timerService) {
    $scope.start = function() {
      timerService.startTimer();
    };

    $scope.stop = function() {
      timerService.stopTimer();
    };

    $scope.reset = function() {
      timerService.resetTimer();
    };
  });
