Here is the complete working steps and please do it very carefully:

1. Here are the basics commands to install angular 8 on your system:

npm install -g @angular/cli 

ng new angularpopup //Create new Angular Project

$ cd angularpopup // Go inside the Angular Project Folder

ng serve --open // Run and Open the Angular Project

http://localhost:4200/ // Working Angular Project Url


2. After done with above, you need to run below commands to set bootstrap environment into your angular 8 application:

npm install --save bootstrap


3. Now you need to add below code into your angular.json file:

"styles": [
            "scripts": ["node_modules/bootstrap/dist/js/bootstrap.min.js"]


4. Now you need to add below code into your src/app/app.component.ts file:

import { Component } from '@angular/core';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  title = 'angulartoastr';
  showModal: boolean;
    this.showModal = true; // Show-Hide Modal Check
  //Bootstrap Modal Close event
    this.showModal = false;



5. Now you need to add below code into src/app/app.component.html file:

<a href="#" (click) = "show()">
  <img id="imageresource" src="https://therichpost.com/wp-content/uploads/2019/09/Angular-8-custom-accordion-working-example-364x225.png" style="width: 125px; height: 125px;">

<!-- Creates the bootstrap modal where the image will appear -->
<div [style.display]="showModal ? 'block' : 'none'" class="modal" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <h4 class="modal-title" id="myModalLabel">Image preview</h4>
    <div class="modal-body">

Hi, it’s very good, thanks you

I have a problem, I try to use the modal on a ngfor
in “mydata” I have 2 images, but it always displays my image 2 in the modal when I click on image 1 and 2.

Have you got an idea please ?


Image {{mydata.id}}

Hi, for this you can use jquery trick $(this) onclick function. First you can get the image src ans paste same image src inside model image src with you can get the same image inside modal.
