javascript - 我的 angularjs 应用程序中的错误

Question

当我尝试导航到我的 angularjs 应用程序时，我收到以下错误消息:

我点击了链接，但看不到问题所在。

这是我的 Controller :

var gameApp = angular.module("gameApp", ['ngRoute','ngSanitize']);

gameApp.directive('mapActivity', function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            scope.$watch('tabledata', function() {

             angular.element('.click#1').addClass('dotted').html($("<img src='images/dot.png'>"));          
                var j = null;
                for(var i = 1; i <= 4; i++)
                {
                    $.ajax({
                        type: 'GET',
                        url: 'lib/terrain.php',
                        dataType: 'html',
                        data: {i: i},
                        success: function(data) {
                            var randomRuta = Math.floor((Math.random() * 100) + 1);
                            angular.element('.click#'+randomRuta).addClass('monster').html($("<img src='images/blackdot.png' title='"+data+"'>"));                  
                        },
                        error: function(xhr, ajaxOptions, thrownError) { alert(thrownError); }
                    });
                    j=i;
                }  
                angular.element('.click').click(function() {
                    if(angular.element(this).hasClass('monster'))
                    {
                        if(confirm('Vill du anfalla monster?'))
                        {
                            alert("Du vann");
                            angular.element('.click.monster'+j).empty();
                            angular.element('.click.monster').removeClass('monster'+j);

                            angular.element('.click.dotted').empty();
                            angular.element('.click.dotted').removeClass('dotted');
                            angular.element(this).addClass('dotted');
                            angular.element('.click.dotted').html($('<img src="images/dot.png">'));
                        }
                    }
                    else
                    {
                        angular.element('.click.dotted').empty();
                        angular.element('.click.dotted').removeClass('dotted');

                        if(!angular.element(this).hasClass('dotted'))
                        {
                            angular.element(this).addClass('dotted');
                            angular.element(this).html($('<img src="images/dot.png">'));
                        }
                    }
                });
            });                     
        }
    };
});

function makeTableFrom(str) {
    var k = 1;
    result = "";

    for(var i = 1; i <= 8; i++) {
        result += '<tr>';

        for(var j = 1; j <= 20; j++) {
            if(str[k] == '#') {
                result += '<td id=' + k + '">#</td>';
            }
            else if(str[k] == '&') {
                result += '<td class="click" val="water" id="' + k + '">&</td>';
            }
            else {
                result += '<td class="click" id="' + k + '"></td>';
            }

            k++;
        }
        result += '</tr>';
    }
    return result;
}

gameApp.controller("gameCtrl", function($scope,$http,link,$location,$sce,$rootScope) {
    $scope.resultLoaded = false;
    $scope.getMonsters = "1";
    var tabledata = ""; //Variable to store pattern for html table

    $http.post("../lib/action.php", {monsters: $scope.getMonsters}).success(function(data) {    
        //tabledata = data; //Assign the pattern
        $scope.result = makeTableFrom(data); //Call the function to build the table based on the pattern
        $scope.resultLoaded = true;
    }).error(function(data) { console.log("error"); });
    console.log(tabledata);

    $scope.safeHtml = function() {
        return $sce.trustAsHtml($scope.result);
    };
    if(link.user) {
        /*$scope.message = "fisk";
        console.log(link.user);*/
    } else {
        /*$scope.message = "Ledsen fisk";
        console.log("Är inte satt");*/
    }
});

这是我的 HTML:

<!DOCTYPE html>
<html ng-app="gameApp">
<head>
<meta content="text/html;charset=UTF-8" http-equiv="content-type" />
</head>
<body ng-controller="gameCtrl">
<div ng-if='resultLoaded'>
    <table ng-bind-html="safeHtml()" map-Activity>
    </table>
</div>
</body>
</tml>
<script src="https://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<script src="https://code.angularjs.org/1.2.22/angular-route.js"></script>
<script src="https://code.angularjs.org/1.2.22/angular-sanitize.js"></script>
<script src="../js/gamecontroller.js"></script>

正如我所说，我点击链接查看错误是由什么引起的，但我不明白它是什么。谁能帮助我？

我用你的代码做了一个笨拙的例子......

我稍微更改了应用程序只是为了制作更好的架构，我不知道您是否按照您在此处发布代码的方式来执行您的应用程序，但如果是，我强烈建议您更改此设置，因为在短时间内您维护你的代码会很头疼......

不管怎样，看看我的笨蛋... link to plunker gameApp example

注意细节，例如 Controller 上的DI(依赖注入(inject)):

controllers.js 文件

angular.module('gameApp_controllers')
    .controller('gameCtrl', ['$scope', '$http', '$location', '$sce', '$rootScope', 'link',
         function($scope, $http, $location, $sce, $rootScope, link){
             // controller content
}]);

此外，app.js 文件更干净，您只需声明您的应用程序和您需要的模块

app.js

var gameApp = angular.module("gameApp", [
  'ngRoute',
  'ngSanitize',
  'gameApp_controllers',
  'gameApp_directives',
  'gameApp_services'
]);

angular.module('gameApp_controllers', []);
angular.module('gameApp_directives', []);
angular.module('gameApp_services', []);

之后，您可以为每个事物( Controller 、服务、指令、路由等)创建一个文件，或者您可以为多个事物(usersController.js、fooController.js 等)创建多个文件

您将如何组织您的应用程序取决于您，但通过这种方式，应用程序将获得更清晰的结构并且更易于理解......

还有一件事:

The code is failing because the controller's injector can't find a way to fulfill the request for a service called "link". Are you trying to reference the link function in the directive as a service?

是的，这是真的，你没有一个“链接”服务，你也没有在你的 Controller 中创建 DI ......
