Usually we use data-target="#myModal"
in the <button>
to open a modal. Right now I need use codes to control when to open the modal.
If I use [hidden]
or *ngIf
to show it, I need remove class="modal fade"
, otherwise, the modal will never show. Like this:
<div [hidden]="hideModal" id="myModal">
However, in this case, after removing class="modal fade"
, the modal won't fade in and has no shade in the background. And what's worse, it will show at the screen bottom instead of screen center.
Is there a way to keep class="modal fade"
and use code to open it?
<button type="button" data-toggle="modal" data-target="#myModal">Open Modal</button>
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
</div>
</div>
</div>

Let me explain the solution. Bit tricky ....... Parent HTML File ........
<!-- parent component html -->
your code....
<div class="d-flex align-items-center flex-nowrap justify-content-end">
<button (click)="openCancelStandingOrder(line)" class="btn btn-primary mx-1" type="button">Delete</button>
</div>
<div *ngIf="isCancelStandingOrderOpen">
<child-component [data]="data" (onCloseModel)="onCloseModal($event)"></child-component>
</div>
Parent TS File
export class ParentComponent {
isCancelStandingOrderOpen: boolean = false;
data: any;
// ....
fetchData() {
// API Call
}
openCancelStandingOrder(line) {
this.isCancelStandingOrderOpen = true;
this.data = line;
}
onCloseModal(reload) {
// prevent unnessecery api calls
if (reload) {
// fetch list data again
this.fetchData();
}
// Do needful
}
}
Child HTML File
<ng-template #cancelStandingOrderModal let-modal>
<div class="modal-header">
<h4 class="modal-title" id="modal-basic-title">Title</h4>
<button type="button" class="btn-close" aria-label="Close" (click)="onDismiss(modal)"></button>
</div>
<div class="modal-body">
<!-- your content here -->
</div>
<div class="modal-footer">
<button type="button" class="btn btn-outline-success" (click)="onSubmit(modal)">Save</button>
<button type="button" class="btn btn-outline-dark" (click)="onExit(modal)">Cancel</button>
</div>
</ng-template>
Child TS File
export class ChildComponent {
// ...
@Input() data: any; // Get data from parent
@Output() public onCloseModal: EventEmitter<boolean> = new EventEmitter();
@ViewChild('cancelStandingOrderModal', { static: false }) public formModal: TemplateRef<any>; // Note: Target html
instance
// Using bootstrap modals: https://ng-bootstrap.github.io/#/components/modal/examples
constructor(private modalService: NgbModal) { }
ngOnInit() {
// Any data manipulation
}
ngAfterViewInit() {
this.openModal();
}
openModal() {
this.modalService.open(this.formModal, {
backdrop: false,
centered: true,
size: 'lg',
keyboard: false, // disable ESC key to close
});
}
onSubmit(modal) {
// Do needful.. api calls etc....
// ...
this.closeModel(modal, true)
}
onExit(modal) {
// Execute any mathod befor closing modal
// like unsaved data alert etc.
this.closeModel(modal, false)
}
onDismiss(modal) {
this.closeModel(modal, false)
}
closeModel(modal: any, reload: boolean = false) {
this.onCloseModal.emit(reload)
modal.close('close');
}
}

Simply, npm install --save @types/bootstrap
try to match typing version with your bootstrap version. E.g. you have Bootstrap 4.3.1 then npm install --save @types/[email protected]

<span (click)="openModal(modalRef)" class="form-control input-underline pl-3 ">Open Abc Modal
</span>
Modal template
<ng-template class="custom-modal" #modalRef let-c="close" let-d="dismiss">

I do not feel there is anything wrong with using JQuery with angular and bootstrap, since it is included when adding bootstrap.
import {.......
declare var $: any;
@component.....
<div id="errorModal" class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" ..............
showErrorModal() {
$("#errorModal").modal('show');
}

I'm currently using Bootstrap 4.3 in Angular 8 and want to open modal window programmatically (without actually clicking on some button as the official demo shows).
Following method works for me:
The general idea is to create a button associated to a modal window.
First make sure after you click this button, it can open the modal.
Then give this button tag an id using hashtag, for example #hiddenBtn
.
In component ts file, import ViewChild from @angular/core
and write below code:
@ViewChild('hiddenBtn', {static: false}) myHiddenBtn;
After that, whenever you want to open this modal window in your component ts code, write following code to simulate click operation
this.myHiddenBtn.nativeElement.click();

We can use jquery to open bootstrap modal.
ngAfterViewInit() {
$('#scanModal').modal('show');
}

I am using a variable to control show and hide and rely on the button the open the modal
ts code:
showModel(){
this.showModal = true;
}
html:
<button type="button" data-toggle="modal" data-target="#myModal" (click)="showModel()>Open Modal</button>
<div *ngIf="showModal" >
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
</div>
</div>
</div>

For me I had to settimeout in addition to @arjun-sk solution's (link), as I was getting the error
setTimeout(() => {
this.modalService.open(this.loginModal, { centered: true })
}, 100);

Think I found the correct way to do it using ngx-bootstrap. First import following classes:
import { ViewChild } from '@angular/core';
import { BsModalService, ModalDirective } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/bs-modal-ref.service';
Inside the class implementation of your component add a @ViewCild property, a function to open the modal and do not forget to setup modalService as a private property inside the components class constructor:
@ViewChild('editSomething') editSomethingModal : TemplateRef<any>;
...
modalRef: BsModalRef;
openModal(template: TemplateRef<any>) {
this.modalRef = this.modalService.show(template);
}
...
constructor(
private modalService: BsModalService) { }
The 'editSomething' part of the @ViewChild declaration refers to the component template file and its modal template implementation (#editSomething):
...
<ng-template #editSomething>
<div class="modal-header">
<h4 class="modal-title pull-left">Edit ...</h4>
<button type="button" class="close pull-right" aria-label="Close"
(click)="modalRef.hide()">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default"
(click)="modalRef.hide()"
>Close</button>
</div>
</ng-template>
And finaly call the method to open the modal wherever you want like so:
console.log(this.editSomethingModal);
this.openModal( this.editSomethingModal );
this.editSomethingModal is a TemplateRef that could be shown by the ModalService.
Et voila! The modal defined in your component template file is shown by a call from inside your component class implementation. In my case I used this to show a modal from inside an event handler.

Best way I have found. Put #lgModal
or some other variable name in your modal.
In your view:
<div bsModal #lgModal="bs-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" (click)="lgModal.hide()" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title">Large modal</h4>
</div>
<div class="modal-body">
...
</div>
</div>
</div>
</div>
In your component
import {Component, ViewChild, AfterViewInit} from '@angular/core';
import {CORE_DIRECTIVES} from '@angular/common';
// todo: change to ng2-bootstrap
import {MODAL_DIRECTIVES, BS_VIEW_PROVIDERS} from 'ng2-bootstrap/ng2-bootstrap';
import {ModalDirective} from 'ng2-bootstrap/ng2-bootstrap';
@Component({
selector: 'modal-demo',
directives: [MODAL_DIRECTIVES, CORE_DIRECTIVES],
viewProviders:[BS_VIEW_PROVIDERS],
templateUrl: '/app/components/modals/modalDemo.component.html'
})
export class ModalDemoComponent implements AfterViewInit{
@ViewChild('childModal') public childModal: ModalDirective;
@ViewChild('lgModal') public lgModal: ModalDirective;
public showChildModal():void {
this.childModal.show();
}
public hideChildModal():void {
this.childModal.hide();
}
ngAfterViewInit() {
this.lgModal.show();
}
}

The Way i used to do it without lots of coding is..
I have the hidden button with the id="employeeRegistered"
On my .ts
file I import ElementRef from '@angular/core'
Then after I process everything on my (click)
method do as follow:
this.el.nativeElement.querySelector('#employeeRegistered').click();
then the modal displays as expected..

This is one way I found. You can add a hidden button:
<button id="openModalButton" [hidden]="true" data-toggle="modal" data-target="#myModal">Open Modal</button>
Then use the code to "click" the button to open the modal:
document.getElementById("openModalButton").click();
This way can keep the bootstrap style of the modal and the fade in animation.

Easy way to achieve this in angular 2 or 4 (Assuming that you are using bootstrap 4)
Component.html
<button type="button" (click)="openModel()">Open Modal</button>
<div #myModel class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title ">Title</h5>
<button type="button" class="close" (click)="closeModel()">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
</div>
</div>
</div>
Component.ts
import {Component, OnInit, ViewChild} from '@angular/core';
@ViewChild('myModal') myModal;
openModel() {
this.myModal.nativeElement.className = 'modal fade show';
}
closeModel() {
this.myModal.nativeElement.className = 'modal hide';
}

Include jQuery as usual inside script tags in index.html.
After all the imports but before declaring @Component, add:
declare var $: any;
Now you are free to use jQuery anywhere in your Angular 2 TypeScript code:
$("#myModal").modal('show');

Here is my full implementation of modal bootstrap angular2 component:
I assume that in your main index.html file (with <html>
and <body>
tags) at the bottom of <body>
tag you have:
<script src="assets/js/jquery-2.1.1.js"></script>
<script src="assets/js/bootstrap.min.js"></script>
modal.component.ts:
import { Component, Input, Output, ElementRef, EventEmitter, AfterViewInit } from '@angular/core';
declare var $: any;// this is very importnant (to work this line: this.modalEl.modal('show')) - don't do this (becouse this owerride jQuery which was changed by bootstrap, included in main html-body template): let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');
@Component({
selector: 'modal',
templateUrl: './modal.html',
})
export class Modal implements AfterViewInit {
@Input() title:string;
@Input() showClose:boolean = true;
@Output() onClose: EventEmitter<any> = new EventEmitter();
modalEl = null;
id: string = uniqueId('modal_');
constructor(private _rootNode: ElementRef) {}
open() {
this.modalEl.modal('show');
}
close() {
this.modalEl.modal('hide');
}
closeInternal() { // close modal when click on times button in up-right corner
this.onClose.next(null); // emit event
this.close();
}
ngAfterViewInit() {
this.modalEl = $(this._rootNode.nativeElement).find('div.modal');
}
has(selector) {
return $(this._rootNode.nativeElement).find(selector).length;
}
}
let modal_id: number = 0;
export function uniqueId(prefix: string): string {
return prefix + ++modal_id;
}
modal.html:
<div class="modal inmodal fade" id="{{modal_id}}" tabindex="-1" role="dialog" aria-hidden="true" #thisModal>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header" [ngClass]="{'hide': !(has('mhead') || title) }">
<button *ngIf="showClose" type="button" class="close" (click)="closeInternal()"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<ng-content select="mhead"></ng-content>
<h4 *ngIf='title' class="modal-title">{{ title }}</h4>
</div>
<div class="modal-body">
<ng-content></ng-content>
</div>
<div class="modal-footer" [ngClass]="{'hide': !has('mfoot') }" >
<ng-content select="mfoot"></ng-content>
</div>
</div>
</div>
</div>
And example of usage in client Editor component: client-edit-component.ts:
import { Component } from '@angular/core';
import { ClientService } from './client.service';
import { Modal } from '../common';
@Component({
selector: 'client-edit',
directives: [ Modal ],
templateUrl: './client-edit.html',
providers: [ ClientService ]
})
export class ClientEdit {
_modal = null;
constructor(private _ClientService: ClientService) {}
bindModal(modal) {this._modal=modal;}
open(client) {
this._modal.open();
console.log({client});
}
close() {
this._modal.close();
}
}
client-edit.html:
<modal [title]='"Some standard title"' [showClose]='true' (onClose)="close()" #editModal>{{ bindModal(editModal) }}
<mhead>Som non-standart title</mhead>
Some contents
<mfoot><button calss='btn' (click)="close()">Close</button></mfoot>
</modal>
Ofcourse title, showClose, mhead and mfoot ar optional parameters.
