Question

我正在尝试将轮播用作新网站的入门模板，但是该功能根本没有显示。我认为我正在努力使js方面正常工作。请查看下面的代码，看看可以做什么。

以下是超大型机的Carousel HTML：

    <div id="myCarousel" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class=""></li>
    <li data-target="#myCarousel" data-slide-to="1" class=""></li>
    <li data-target="#myCarousel" data-slide-to="2" class="active"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item">
      <img class="first-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="First slide">
      <div class="container">
        <div class="carousel-caption text-left">
          <h1>Example headline.</h1>
          <p>Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
          <p><a class="btn btn-lg btn-primary" href="#" role="button">Sign up today</a></p>
        </div>
      </div>
    </div>
    <div class="carousel-item">
      <img class="second-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="Second slide">
      <div class="container">
        <div class="carousel-caption">
          <h1>Another example headline.</h1>
          <p>Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
          <p><a class="btn btn-lg btn-primary" href="#" role="button">Learn more</a></p>
        </div>
      </div>
    </div>
    <div class="carousel-item active">
      <img class="third-slide" src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="Third slide">
      <div class="container">
        <div class="carousel-caption text-right">
          <h1>One more for good measure.</h1>
          <p>Cras justo odio, dapibus ac facilisis in, egestas eget quam. Donec id elit non mi porta gravida at eget metus. Nullam id dolor id nibh ultricies vehicula ut id elit.</p>
          <p><a class="btn btn-lg btn-primary" href="#" role="button">Browse gallery</a></p>
        </div>
      </div>
    </div>
  </div>
  <a class="carousel-control-prev" href="#myCarousel" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#myCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

此处是相应的component.ts：

import { Component, OnInit } from '@angular/core';
import 'popper.js';
import 'bootstrap';
import * as $ from 'jquery';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {

  constructor() { }

    ngOnInit() {
    }

    ngAfterViewInit() {
      $('.carousel').carousel();
    }

  }

和angular.json：

    ..."styles": [
      "node_modules/bootstrap/dist/css/bootstrap.min.css",
      "src/styles.css"
    ],
    "scripts": [
      "node_modules/jquery/dist/jquery.min.js",
      "node_modules/bootstrap/dist/js/bootstrap.min.js"
    ]...

可能缺少明显的东西。无论如何，请尽可能提供帮助。
