今天的代码让我再次发疯,尤其是 Angular 服务中带有显示模块模式的 Angular。当我开始时,我发现它没有任何问题......现在除了不工作......我不知道。任何方式都知道我想知道它是有角度的还是我在做一些愚蠢的事情。这是代码:

angular.module('homeAdmin.services', [])
.factory('dataService', function ($http, $q) {
    'use strict';
    function _contentTypes(){
        var intialized = false;
        var _models = [];
        function _isReady() {
            return intialized;
        };
        return {
            isReady: _isReady
        };
    };

    return {
        contentTypes: _contentTypes
    };
});

这就是它的名字:

var contentTypeCtrl = ['$scope','$http','$window','dataService', function ($scope, $http, $window, dataService) {
'use strict';
$scope.isBusy = false;
$scope.data = dataService;
$scope.contentType = {};

$scope.name = 'Content Type';
$scope.init = function () {
    console.log('contentTypeCtrl initialized');
};

if (dataService.contentTypes.isReady() == false) {
    console.log("Hello let's load some data!"); 
}}]

这是 Firefox 给我手指的方式:

帮助?任何人??

这是一个如何使用 isready 函数的示例:

    if (dataService.contentTypes.isReady() == false) {
    $scope.isBusy = true;
    dataService.contentTypes.get()
        .then(function () {
        }, function () {
            alert('contentTypes retrieval failed');
        })
        .then(function () {
            $scope.isBusy = false;
        });
}

并像这样使用数据:

<tr data-ng-repeat="model in data.contentTypes.models">

我不精通 Angular,所以如果我离开这里,请原谅(-!

看起来 isReady() 是通过调用 contentTypes() 返回的 - 但我没有看到对 contentTypes 的调用 - 只有一个引用,它指向closure-fn _contentTypes。

是否有可能改为如下所示?

dataService.contentTypes().isReady()

*添加 '()' 以实际调用 contentTypes 函数,该函数又将返回 isReady() 函数

您不能将 Module Revealing Pattern 与工厂一起使用,它只会在实例化时返回属性的默认值。如果要使用模块显示模式,则需要使用服务。
