AngularJS Typescript 路由

Question

我正在使用 following template 配置 AngularJS/Typescript Web 应用程序并收到以下错误。

The following error is appearing when I run the application:
0x800a139e - JavaScript runtime error: [$injector:modulerr] Failed to instantiate module app due to:

Error: [$injector:nomod] Module 'app' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

我检查了this thread 并确保我确实引用了 angular-route.js

app.ts - Easier version to view + index.html

  /// <reference path="./typings/angularjs/angular.d.ts" />
'use strict';

// Create and register modules
var modules = ['app.controllers','app.directives', 'app.filters', 'app.services'];
modules.forEach((module) => angular.module(module, []));
angular.module('app', modules);

// Url routing
angular.module('app').config(['$routeProvider',
    function routes($routeProvider: ng.IRouteProvider) {
        $routeProvider
            .when('/', {
                templateUrl: 'views/MyView.html',
                controller: 'app.controllers.MyController'
            })
            .otherwise({
                redirectTo: '/'
            });
    }
]);

module app {
    export module controllers {}
    export module directives {}
    export module filters {}
    export module services {}

    export interface IController {}
    export interface IDirective {
        restrict: string;
        link($scope: ng.IScope, element: JQuery, attrs: ng.IAttributes): any;
    }
    export interface IFilter {
        filter (input: any, ...args: any[]): any;
    }
    export interface IService {}

    /**
     * Register new controller.
     *
     * @param className
     * @param services
     */
    export function registerController (className: string, services = []) {
        var controller = 'app.controllers.' + className;
        services.push(app.controllers[className]);
        angular.module('app.controllers').controller(controller, services);
    }

    /**
     * Register new filter.
     *
     * @param className
     * @param services
     */
    export function registerFilter (className: string, services = []) {
        var filter = className.toLowerCase();
        services.push(() => (new app.filters[className]()).filter);
        angular.module('app.filters').filter(filter, services);
    }

    /**
     * Register new directive.
     *
     * @param className
     * @param services
     */
    export function registerDirective (className: string, services = []) {
        var directive = className[0].toLowerCase() + className.slice(1);
        services.push(() => new app.directives[className]());
        angular.module('app.directives').directive(directive, services);
    }

    /**
     * Register new service.
     *
     * @param className
     * @param services
     */
    export function registerService (className: string, services = []) {
        var service = className[0].toLowerCase() + className.slice(1);
        services.push(() => new app.services[className]());
        angular.module('app.services').factory(service, services);
    }
}

我是一个 TS/Angular 新手，因此我们将不胜感激。

潜在重复：AngularJS + TypeScript: cannot inject $routeProvider

Answer 1

您需要对该模板进行一些更改才能使其正常工作。

Full source here

首先确保您有正确的参考。包括对angular-route.d.ts的引用

/// <reference path="./typings/angularjs/angular.d.ts" />
/// <reference path="./typings/angularjs/angular-route.d.ts" />

'use strict';

// Create and register modules
var modules = ['app.controllers','app.directives', 'app.filters', 'app.services'];
modules.forEach((module) => angular.module(module, []));

要使用$routeProvider，你必须在你的模块中包含ngRoute模块，但是因为我们不想用angular注册它，因为它已经存在，我们需要像这样推送模块：

// *** Push ngRoute or $routeProvider won't work ***
modules.push("ngRoute");

angular.module('app', modules);

那么你需要将$routeProvider的类型从ng.IRouteProvider改成ng.route.IRouteProvider，因为那个定义是错误的。

// Url routing
angular.module('app').config(['$routeProvider',
    function routes($routeProvider: ng.route.IRouteProvider) { // *** $routeProvider is typed with ng.route.IRouteProvider ***
        $routeProvider
            .when('/', {
                templateUrl: 'views/MyView.html',
                controller: 'app.controllers.MyController'
            })
            .otherwise({
                redirectTo: '/'
            });
    }
]);

Next TypeScript 不接受空模块。所以拥有export module controllers {} 等是没有意义的，因为 TSC 不会包含它们，并且它们将是未定义的给出错误。除非您要在应用程序中定义至少一个控制器、指令、过滤器和服务。但这可以通过简单地包含 null;

来解决

module app {
    export module controllers { null; }
    export module directives { null; }
    export module filters { null; }
    export module services { null; }

    export interface IController {}
    export interface IDirective {
        restrict: string;
        link($scope: ng.IScope, element: JQuery, attrs: ng.IAttributes): any;
    }
    export interface IFilter {
        filter (input: any, ...args: any[]): any;
    }
    export interface IService {}

    /**
     * Register new controller.
     *
     * @param className
     * @param services
     */
    export function registerController (className: string, services = []) {
        var controller = 'app.controllers.' + className;
        services.push(app.controllers[className]);
        angular.module('app.controllers').controller(controller, services);
    }

    /**
     * Register new filter.
     *
     * @param className
     * @param services
     */
    export function registerFilter (className: string, services = []) {
        var filter = className.toLowerCase();
        services.push(() => (new app.filters[className]()).filter);
        angular.module('app.filters').filter(filter, services);
    }

    /**
     * Register new directive.
     *
     * @param className
     * @param services
     */
    export function registerDirective (className: string, services = []) {
        var directive = className[0].toLowerCase() + className.slice(1);
        services.push(() => new app.directives[className]());
        angular.module('app.directives').directive(directive, services);
    }

    /**
     * Register new service.
     *
     * @param className
     * @param services
     */
    export function registerService (className: string, services = []) {
        var service = className[0].toLowerCase() + className.slice(1);
        services.push(() => new app.services[className]());
        angular.module('app.services').factory(service, services);
    }
}

现在应该可以了，您可以注册控制器、过滤器、服务和指令。如：

module app.controllers
{
    export class testCtrl implements IController
    {
        constructor()
        {
            console.log("Test Controller");
        }
    }
}

app.registerController('testCtrl');

当引用一个控制器，或服务时使用全名。即：

<div ng-controller="app.controllers.testCtrl"></div>

请记住在您的 html 中在 angular.js 之后引用 angular-route.js。即：

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.12/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.12/angular-route.js"></script>

我在这里找到了我的解决方案a link:

当我试图包含一个不存在的模块依赖项时会发生这种情况。发生这种情况的原因有很多，例如删除模块的 index.html 脚本但留下模块依赖关系，甚至拼写错误的模块依赖关系。 （原来我的问题是前者。）所以一旦你知道这一点就很容易解决。
