将 Underscore.js 注入 Angular 控制器

Question

我尝试了两种解决方案 here 无济于事。

这是我的错误：

angular.js:68 Uncaught Error: [$injector:modulerr] Failed to instantiate module flavorApplication due to: Error: [$injector:unpr] Unknown provider: underscore

这是我的模块代码：

var underscore = angular.module('underscore', []);
underscore.factory('_', ['$window', function() {
  return $window._;
}]);

这是我的应用程序配置：

(function(){
  angular.module("flavorApplication",
    ['ui.bootstrap',
        'ui.router',
        'angular-loading-bar',
        'angular-confirm',
        ]);
        angular.module("flavorApplication").config(['$stateProvider', '$urlRouterProvider', '$locationProvider', 
        'underscore', function ($stateProvider, $urlRouterProvider, $locationProvider, underscore){

我在这里尝试将其注入控制器（可能是我出错的地方）

(function () {
    'use strict';

    angular
        .module('flavorApplication')
        .controller('UsedSearchesController', UsedSearchesController);

    UsedSearchesController.$inject = ['$stateParams', '$state', 'DataService', '_'];
    function UsedSearchesController($stateParams, $state, DataService, _) {
        var vm = this;
        vm.currentSearches = $stateParams.search.split("|")


        activate(vm);

        ////////////////

        function activate(vm, _) {
            vm.removeSearch = function (searchTerm) {
              $stateParams.search =  _.filter(vm.currentSearches, 
              function(search){return search !== searchterm}).join("|")
                $state.go('home');
            }
        }
    }
})();

你错过了 $window 依赖注入你的工厂

underscore.factory('_', ['$window', function($window) {

您无法在 angular 的配置阶段获得 factory/service 单例对象的其他事情，您无法在那里获得该对象。

//remove 'underscore' dependency from config phase like below.
angular.module("flavorApplication").config(['$stateProvider', '$urlRouterProvider', '$locationProvider',
   function ($stateProvider, $urlRouterProvider, $locationProvider){

此外，您不需要在 activate 函数中添加 _ 作为参数，

function activate(vm) { //<-- remove _ from here

Don't forget to inject underscore module to flavorApplication module so that would make available _ object throughout application modules & components.

angular.module("flavorApplication",
['ui.bootstrap',
    'ui.router',
    'angular-loading-bar',
    'angular-confirm',
    'underscore' //<-- added underscore module here
]);
