Angular ng引导预输入示例未加载-角度

我已经建立了一个基本的Angular站点，纯粹是为了测试ng引导位，我正在努力让第一个Typeahead示例正常工作。 我目前正在使用Angular 2.4

这是我的应用程序模块

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';
import { UniversalModule } from 'angular2-universal';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { JsonpModule } from '@angular/http';

import { AppComponent } from './components/app/app.component'
import { NavMenuComponent } from './components/navmenu/navmenu.component';
import { HomeComponent } from './components/home/home.component';
import { FetchDataComponent } from './components/fetchdata/fetchdata.component';
import { CounterComponent } from './components/counter/counter.component';

import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
import { NgbdTypeaheadBasic } from './components/typeahead/typeahead-basic';

@NgModule({
    bootstrap: [ AppComponent ],
    declarations: [
        AppComponent,
        NavMenuComponent,
        CounterComponent,
        FetchDataComponent,
        HomeComponent,
        NgbdTypeaheadBasic
    ],
    imports: [
        UniversalModule, // Must be first import. This automatically imports BrowserModule, HttpModule, and JsonpModule too.
        FormsModule,
        ReactiveFormsModule,
        RouterModule.forRoot([
            { path: '', redirectTo: 'home', pathMatch: 'full' },
            { path: 'home', component: HomeComponent },
            { path: 'counter', component: CounterComponent },
            { path: 'fetch-data', component: FetchDataComponent },
            { path: 'type-ahead', component: NgbdTypeaheadBasic },
            { path: '**', redirectTo: 'home' }
        ]),
        NgbModule.forRoot()
    ]
})
export class AppModule {
}

这是我的typeahead基本类型脚本文件

import { Component } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/debounceTime';
import 'rxjs/add/operator/distinctUntilChanged';

const states = ['Alabama', 'Alaska', 'American Samoa', 'Arizona', 'Arkansas', 'California', 'Colorado',
    'Connecticut', 'Delaware', 'District Of Columbia', 'Federated States Of Micronesia', 'Florida', 'Georgia',
    'Guam', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine',
    'Marshall Islands', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana',
    'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Carolina', 'North Dakota',
    'Northern Mariana Islands', 'Ohio', 'Oklahoma', 'Oregon', 'Palau', 'Pennsylvania', 'Puerto Rico', 'Rhode Island',
    'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virgin Islands', 'Virginia',
    'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'];

@Component({
    selector: 'ngbd-typeahead-basic',
    templateUrl: './typeahead-basic.html',
    styles: [`.form-control { width: 300px; }`]
})
export class NgbdTypeaheadBasic {
    public model: any;

    search = (text$: Observable<string>) =>
        text$
            .debounceTime(200)
            .distinctUntilChanged()
            .map(term => term.length < 2 ? []
                : states.filter(v => new RegExp(term, 'gi').test(v)).splice(0, 10));
}

我使用的是优秀的，问题似乎围绕着服务器端预渲染。我从Views/Home/Index.cshtml中的元素中删除了asp prerender模块属性。

我使用的是优秀的，问题似乎与服务器端预渲染有关。我从Views/Home/Index.cshtml中的元素中删除了asp prerender模块属性。

这里也有同样的问题，问题是什么（同样的问题，什么问题？：(
