Question

我正在将一个服务注入一个指令中，对于某些实例，这个服务返回undefined可以解释我做错了吗？

以下是代码的一部分内容。 https://plnkr.co/edit/H2x2z8ZW083NndFhiBvF?p=preview

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

app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.players = ["A","B","C"];
});

app.factory('PlayerListS', [function() {
    var playerList = [];

    function getList() {
        return playerList;
    }
    function addToList(name) {
        playerList.push(name);
    }

    return {
        addToList :addToList,
        getList: getList
    }

}]);
app.directive("player",['PlayerListS', function (PlayerListS) {
return {
    restrict: 'E',
    scope: {
        person:'@person',
        add:'&add'
    },
    replace: false,
    templateUrl: "player.html",
    controller: function($scope, $element, $compile) {
          $scope.add = function(name) {
              PlayerListS.addToList(name);
              console.log(PlayListS.getList());
          }
    }
};
}]);

您的控制台中有一个拼写错误，因为代码会导致错误。以下列方式更改指令
