angular - 如何将 Bootstrap Accordion 添加到 Angular 应用程序

Question

我正在尝试在下面的 Angular 应用程序中添加一个 Bootstrap Accordion:

<div class="accordion" id="accordionExample">
    <div class="card">
        <div class="card-header" id="headingOne">
            <h5 class="mb-0">
                <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
                    Collapsible Group Item #1
                </button>
            </h5>
        </div>

        <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordionExample">
            <div class="card-body">
                Anim
            </div>
        </div>
    </div>

    <div class="card">
        <div class="card-header" id="headingTwo">
            <h5 class="mb-0">
                <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
                    Collapsible Group Item #2
                </button>
            </h5>
        </div>
        <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionExample">
            <div class="card-body">
            Anim
            </div>
        </div>
    </div>

    <div class="card">
        <div class="card-header" id="headingThree">
            <h5 class="mb-0">
                <button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
                    Collapsible Group Item #
                </button>
            </h5>
        </div>
        <div id="collapseThree" class="collapse" aria-labelledby="headingThree" data-parent="#accordionExample">
            <div class="card-body">
                Anim
            </div>
        </div>
    </div>
</div>

我在构建之前运行了以下 NPM 安装:

npm i bootstrap

npm i ngx-bootstrap

但是当我点击其中一个 Accordion Titles 时，什么也没有发生。
有人可以告诉我我缺少什么设置吗？非常感谢!

您正在使用 Bootstrap 的“普通”版本。

确保您已将 Bootstrap 样式添加到全局 styles.css 中的应用程序中。或 style.scss文件:

CSS 版本
@import '~bootstrap/dist/css/bootstrap.min.css';
SCSS版本
@import "~bootstrap/scss/bootstrap";

导入AccordionModule来自 ngx-bootstrap给您的AppModule .

import { AccordionModule } from 'ngx-bootstrap/accordion';

@NgModule({
  imports: [AccordionModule.forRoot(),...]
})
export class AppModule{}

使用 ngx-bootstrap 中提供的组件不是“普通”的 html 版本:

<accordion>
  <accordion-group heading="Static Header">
    This content is straight in the template.
  </accordion-group>
  <accordion-group heading="Another group">
    <p>Some content</p>
  </accordion-group>
  <accordion-group heading="Another group">
    <p>Some content</p>
  </accordion-group>
  <accordion-group heading="Another group">
    <p>Some content</p>
  </accordion-group>
</accordion>

Install instructions for ngx-bootstrap

Accordion Component of ngx-bootstrap

添加动画

要添加动画，您需要添加属性 isAnimated到父组件 accordion :

<accordion [isAnimated]="true">
<!-- ... -->
</accordion>

只打开一架 Accordion

要只打开一个 Accordion ，您需要添加属性 closeOthers到父组件 accordion :

<accordion [isAnimated]="true" [closeOthers]="true">
<!-- ... -->
</accordion>
