Question

无法让Bootstrap 4.0 modal在Angular 4项目中工作。

模态在简单的静态HTML页面中运行良好：https://jsfiddle.net/Lq73nfkx/1/

<!-- MODAL -->
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

你可以在下面的屏幕截图中看到，按下显示模态导致html在几个地方被更改，不仅在模型HTML本身内，而且文档的<body>元素被操作为好。

执行HTML操作的Bootstrap JavaScript似乎没有在Angular 4项目中触发，当我在项目中使用完全相同的代码时，HTML根本没有改变。

我是否应该使用带有Angular 4的Bootstrap？或者我应该使用另一个不是Bootstrap的Angular 4的Modal解决方案吗？

Answer 1

您可以使用ngx-bootstrap库来执行此操作。安装库后，请按照以下步骤操作。

第1步：将以下代码添加到app.module.ts文件中。

import { ModalModule, BsModalRef } from 'ngx-bootstrap';

@NgModule({
 imports: [ModalModule.forRoot(),...],
 providers: [BsModalRef]
})

第2步：复制以下代码并粘贴到app.commponent.html。

    <button type="button" class="btn btn-primary" (click)="openModal(template)">Create template modal</button>

<ng-template #template>
    <div class="modal-header">
        <h4 class="modal-title pull-left">Modal</h4>
        <button type="button" class="close pull-right" aria-label="Close" (click)="modalRef.hide()">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    <div class="modal-body">
        This is a modal.
    </div>
</ng-template>

Step3：最后将以下代码复制到app.component.ts。

import { Component, TemplateRef } from '@angular/core';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/bs-modal-ref.service';

export class AppComponent {
    modalRef: BsModalRef;
    constructor(private modalService: BsModalService) {}

    openModal(template: TemplateRef<any>) {
        this.modalRef = this.modalService.show(template,{ backdrop: 'static', keyboard: false });
    }
}

你可以尝试在导入bootstrap cdn

之后在jQuery之后添加TetherJS

Bootstrap 4.0＆＃34; Modal＆＃34;不使用Angular 4
