如何调用来自外部的Angularjs工厂函数 [英] How to call an Angularjs factory function from outside

问题描述

我有一个角模块/工厂是这样的：

I have an angular module / factory like this:

var app = angular.module('webportal', ['vr.directives.slider', 'angular-flexslider', 'LocalStorageModule', 'multi-select']);

    app.factory('portal', ['uri', function (uri) {
        portal = {};
        portal.getURLParameter = function (name) {
            var hash;
            var vars = [];

            var indexOfQuestion = window.location.href.indexOf('?');

            if (indexOfQuestion != -1) {

                var hashes = window.location.href.slice(indexOfQuestion + 1).split('&');
                for (var i = 0; i < hashes.length; i++) {

                    if (typeof name == 'undefined')
                        vars.push(hashes[i]);

                    else {
                        hash = hashes[i].split('=');
                        if (hash[0] = name)
                            return hash[1];
                    }
                }
            }
        };
        return portal;
    }]);

现在我试图调用 getURLParameter 从外部的角度，像这样的：

Now i am trying to call the getURLParameter from outside angular, like this:

angular.injector(['webportal']).get('portal').getURLParameter('blah');

当然，这并不工作，无法与

Of course that does not work and fails with:

错误：[$喷油器：modulerr]未能实例由于模块门户网站
  到：[$喷油器：modulerr]无法实例模块
  vr.directives.slider由于：未能：[$注射器modulerr]
  实例化模块ngTouch由于：[$喷油器：unpr]未知提供商：

因此​​，谁能告诉我什么是调用正确的方法？

So can anyone tell me what is the proper way to call this?

推荐答案

找到了答案周围多一点戳后：

found the answer after poking around a bit more:

angular.element(document.body).injector().get('portal').getURLParameter('blaha')
