How to use bootstrap popover in angular 7 using jquery?

Question

I am trying to implement bootstrap4 popover using jquery in angular7. I have included "popper.js" in index.html and included using npm too. but it's not working.

Uncaught TypeError: jquery__WEBPACK_IMPORTED_MODULE_2__(...).popover is not a function

this error only appears in the console.

HTML:(sample.component.html)

<button id="option2" autocomplete="off" data-toggle="popover"> Public</button>

Jquery: (sample.component.ts)

import { Component, OnInit } from '@angular/core';
import * as $ from 'jquery';

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

  constructor() { }   
  ngOnInit() {   
    $(document).ready(function(){   
      $('[data-toggle="popover"]').popover();     
      $('#option2').popover({
         html: true,
        content: function() {
          return $("#div").html();
        },
         placement: 'bottom'
      });            
    });
  }

How to achieve bootstrap popover in angular 7?

Answer 1

Change your component file to that way:

import { Component, OnInit } from '@angular/core';
declare var $: any; // ADD THIS
import * as $ from 'jquery';

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

  constructor() { }   
  ngOnInit() {   
    $('[data-toggle="popover"]').popover();
  }

You don't need use $(document).ready() because the NgOnInit() do the same thing. And the $('[data-toggle="popover"]').popover(); will start all Popover you have in your component.

You can use title, data-placement and data-content attributes for make the Popover like:

<button id="option2" autocomplete="off" data-toggle="popover" data-placement="bottom" title="popover's title" data-content="popover's text"> Public</button>

Or you can initialize the popover with the function that you used in NgOnInit() :

$('#option2').popover({
         html: true,
        content: function() {
          return $("#div").html();
        },
         placement: 'bottom'
      }); 

Hope this helps.
