Question

我正在使用Angular 1.5.7和Typescript的现有应用程序添加功能，我之前没有使用过这些技术，而且已经遇到了死胡同。

我收到以下错误 TypeError：无法读取未定义的属性'InviteUser'

这是我的代码。

AddEditContactController.ts

import CT = require('../../models/commontypes');
import E = require('../../models/Employers');
import * as Common from "../../../common/commonapp";
import EmployerService = require('../services/EmployerService');

class AddEditContactController {
    static controllerId = 'addEditContact';
    static $inject = ['$uibModalInstance', '$routeParams', '$http', Common.LookupService.serviceId, 'Item' ];

    public InviteSent: boolean = false;
    public OrganisationID: number;

    constructor(protected $modalInstance: ng.ui.bootstrap.IModalServiceInstance,
        private $routeParams: E.Employed.IViewEmployerProfesionalBodyRouteParams,
        protected $http: ng.IHttpService,
        private LookupService: Common.LookupService,
        public Item: E.Employed.Contact,
        private EmployerService: EmployerService)
        {
            this.OrganisationID = +$routeParams.EmployerID; 
        }

    public Cancel() {
        this.$modalInstance.dismiss('cancel');
    }

    public Save(form) {
        if (form.$valid) {
            //don't need to pass anything back because the same instance we passed in will have been manipulated
            this.$modalInstance.close(this.Item);
        }
    }

    public SendContactInvite(form) {
        if (form.$valid) {
            this.EmployerService.InviteUser(this.Item.ID, this.OrganisationID).then(() => {  // The Error is pointing to this line 
                this.InviteSent = true;
            });
        }
    } 

}

    export = AddEditContactController;

错误指向SendContactInvite函数中的行，但ItemID和OrganisationID都包含一个值，我错过了什么吗？

这是其余的

EmployerService.ts

  InviteUser(ContactID: number, OrganisationID: number): ng.IHttpPromise<{}> {
        return this.$http({
            url: '/employer/InviteUser',
            method: 'POST',
            data: {
                ContactID: ContactID,
                OrganisationID: OrganisationID 
            }
        });
    }

AddEditContact.html

<div class="form-group">
  <div class="pull-right  ng-scope">
    <button type="button" class="btn btn-employed" ng-click="modal.SendContactInvite(form)" ng-disabled="form.$invalid"><span class="glyphicon glyphicon-send" aria-hidden="true" uib-tooltip="Invite contact to become a member" tooltip-append-to-body="true"></span> Send Invite</button>
  </div>

任何帮助/建议将不胜感激，提前谢谢

当您指定应该在类上注入的内容时，未指定EmployerService

static $inject = [
  '$uibModalInstance', 
  '$routeParams', 
  '$http', 
  Common.LookupService.serviceId, 
  'Item'
];

您需要将其添加到注入项目列表中：

static $inject = [
  '$uibModalInstance', 
  '$routeParams', 
  '$http', 
  Common.LookupService.serviceId, 
  'Item',
  'EmployerService' // <---- NEW!!!
];

获得以下错误 - TypeError：无法读取未定义的属性“InviteUser”
