Question

我具有以下代码，可以在单击按钮时打开模式。如何从组件ts文件中的函数打开模态？我的html是这样的：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
  <div>
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open The Modal Box</button>

  <!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">        
        <h4 class="modal-title">Sample Modal</h4>
        <button type="button" class="close" data-dismiss="modal">&times;</button>
      </div>
      <div class="modal-body">
        <p>Click OK to close.</p>
        <input [(ngModel)]="name"><br>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Ok</button>
      </div>
    </div>

  </div>
</div>
</div>

弹出窗口应来自组件中的以下组件：

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  

  OpenModalFun() {
      //Code to open modal pop-up
  }
  
  closeModalFun() {
      //Code to close modal pop-up
  }
 
}

我不知道如何从TS文件打开弹出窗口。请帮忙。预先感谢。

您可以像下面这样隐藏按钮[hidden]="true"：

<button id="openModalButton" type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" [hidden]="true">Open The Modal Box</button>

并显示功能的模态（模拟按钮单击）：

import { Component } from '@angular/core';

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


  OpenModalFun() {
      document.getElementById("openModalButton").click();
  }

  closeModalFun() {
      //Code to close modal pop-up
  }

}

ElementRef

<button #btn id="openModalButton" type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" [hidden]="true">Open The Modal Box</button>

并显示功能的模态（模拟按钮单击）：

import { Component } from '@angular/core';

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

  @ViewChild('btn') fileInput:ElementRef;
  OpenModalFun() {
      this.btn.nativeElement.click();
  }

  closeModalFun() {
      //Code to close modal pop-up
  }

}

如果您使用的是ngbootstrap，则可以从TS文件轻松完成

ngbootstrap模态弹出示例

Angular 5中来自组件Typescript文件的ngbootstrap模态弹出窗口
