如何在 Angular 的同一页面上使用多个 ngx-slick-carousel？

Question

我在我的页面上使用了光滑的轮播，但它给了我一个错误并且不显示第二个轮播。 滑块.component.ts

<div *ngIf="mainSlider">
    <div class="main__slider">
        <ngx-slick-carousel class="carousel" #slickModal="slick-carousel" [config]="slideConfig">

                                        </div>
                                    </div>
                                </div>
                                <div class="events__item-title">
                                    ${{banner.title}}
                                </div>
                                <div class="events__item-text">
                                    ${{banner.description}}
                                </div>
                            </a>
                        </div>
                    </div>
                </div>
            </div>
        </ngx-slick-carousel>
    </div>
</div>

如您所见，我有mainSlider和eventsSlider ，我还尝试为每个圆滑的轮播提供个人#slickModal名称（@ViewChild 也正在观看自己的模式）。
滑块.components.ts

import { Component, OnInit, ViewChild, Input } from '@angular/core';
import { SlickCarouselComponent } from 'ngx-slick-carousel';

import { eventsBanners } from './banners';

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

  @Input() mainSlider: boolean;
  @Input() eventsSlider: boolean;

  @ViewChild('slickModal') slickModal: SlickCarouselComponent;
  @ViewChild('eventsModal') eventsModal: SlickCarouselComponent;
...

我在主页上导入 app-slider
主页.component.html

<section class="main">
    <div class="container">
        <div class="main__inner">
            <app-slider mainSlider="true"></app-slider>
        </div>
    </div>
</section>
<section class="events">
    <div class="container">
        <app-slider eventsSlider="true"></app-slider>
    </div>
</section>

在第一个横幅上，我正在更改进度条的宽度，然后使 next() 函数slider.component.ts

  next() {
    console.log(this.slickModal) // gives first modal
    console.log(this.eventsModal) // gives undefined
    this.slickModal.slickNext();
  }

这是一个错误

类型错误：无法读取未定义的属性“slickNext”

有人可以帮忙解决这个问题吗？ 我应该如何在同一页面/文件上使用 2 <ngx-slick-carousel> ？

Answer 1

问题是我的第二个滑块的 html 不正确，两个滑块可以工作。 据我了解在ngx-slick-carousel孩子应该有ngxSlickItem

<div *ngIf="eventsSlider">
<div class="events-slider">
    <div class="events-slider__arrows news-arrows active-arrows"></div>
    <div class="events-slider__arrows activity-arrows"></div>
    <div class="events__tabs">
        <div class="title tab news-tab active">
            news
        </div>
        <div class="switch first-on">
            <span></span>
        </div>
        <div class="title tab activity-tab">
            events
        </div>
    </div>
    <div class="events__tab-content">
        <div class="news-item tab-item active-tab">
            <div class="news-slider">
                <ngx-slick-carousel class="carousel" #eventsModal="slick-carousel" [config]="slideConfig">
                    <a ngxSlickItem *ngFor="let banner of eventsBanners" href="#" class="events__item">
                        <div class="events__item-image">
                            <img src="assets/img/{{ banner.img }}.png" alt="">
                        </div>
                        <div class="events__item-wrapper">
                            <div class="date-view">
                                <div class="date-view__date">
                                    <img src="images/icons/calendar.svg" alt="">{{banner.date}}
                                </div>
                                <div class="date-view__view">
                                    <img src="images/icons/eye.svg" alt="">{{banner.views}}
                                </div>
                            </div>
                        </div>
                        <div class="events__item-title">
                            {{banner.title}}
                        </div>
                        <div class="events__item-text">
                            {{banner.description}}
                        </div>
                    </a>
                </ngx-slick-carousel>
            </div>
        </div>
    </div>
</div>

更新 1

但我仍然无法处理 next() 函数。 函数改变了我的第一个 slick，但也给出了一个错误，它不能 slickNext() of undefined 。 他仍然认为他应该对两个 modals 都使用 slickNext() ，即使我在开始时将它们分开。

next() {
    this.mainBanner.slickNext(); 
 }

  @ViewChild('slickModal') mainBanner: SlickCarouselComponent;
  @ViewChild('eventsModal') eventsModal: SlickCarouselComponent;

类型错误：无法读取未定义的属性“slickNext”
