Angular 静态类对象属性在运行时未定义
我有一个奇怪的问题 我有这门课Angular 静态类对象属性在运行时未定义,angular,typescript,webpack,Angular,Typescript,Webpack,我有一个奇怪的问题 我有这门课 export class PageList { static readonly About: IPageInfo = Object.seal({ menuTitle: 'About', url: 'about', trainingType: undefined, trainingName: undefined }); static readonly PrivacyFull: IPageInfo = Object.se
export class PageList {
static readonly About: IPageInfo = Object.seal({
menuTitle: 'About',
url: 'about',
trainingType: undefined,
trainingName: undefined
});
static readonly PrivacyFull: IPageInfo = Object.seal({
menuTitle: 'FullPrivacyDetails',
url: 'privacy-full',
trainingType: undefined,
trainingName: undefined
});
}
import { PageList } from 'src/app/models/classes/page-list.model';
@Component({
selector: 'app-privacy',
templateUrl: './privacy.page.html',
styleUrls: ['./privacy.page.scss']
})
export class PrivacyPage implements OnInit {
onSeeAll() {
this.navService.push(PageList.PrivacyFull)
}
}
this.navService.pushPrivacyFullmenutile未定义的
在Chrome开发工具中查看它时，会发现它是未定义的
，但如果我看到该文件（DevTools喜欢），它就是我编写的文件
我做错什么了？我真的看不出来
或者Typescript/Webpack是否以错误的方式编译
编辑：当我看到生成的webpack模块时，它也是未定义的
根据需要进行编辑，这里是我的package.json

我记得看到过那种行为，但我无法重现。你使用什么版本的Typescript？我的package.json
有~3.1.6
，但我在package lock.json
中看到一些角度依赖项使用3.2.4
，因为我在过去看到过这一点，在这种情况下，我倾向于使用带有readonly
成员属性的单例服务。@ConnorsFan我可以尝试一下，尽管我很确定我会在某些地方得到一些循环依赖，但我不明白为什么使用服务会导致循环依赖。看见
