Topic: Calling modal in component from another component

worksonline pro asked 6 years ago

Hi, We are trying to open a modal in a component(navbar) from within another component(Inbox) When clicking link in navbar (click)="inbox.show() inbox modal in Inbox component should show. Instead we get TypeError: "_co.inbox is undefined"

Dear worksonline, You need to use service to communicate between components. I prepared an example for you: app.component.html:

<mdb-navbar SideClass="navbar navbar-expand-lg navbar-dark indigo">

<!-- Navbar brand -->

<logo><aclass="navbar-brand"href="#">Navbar</a></logo>

<!-- Collapsible content -->

<links>

<!-- Links -->

<ulclass="navbar-nav mr-auto">

<liclass="nav-item">

<a (click)="openModal()"class="nav-link waves-light"mdbWavesEffect>Inbox show</a>

</li>

</ul>

<!-- Links -->

<!-- Search form -->

<formclass="form-inline waves-light"mdbWavesEffect>

<divclass="md-form mt-0">

<inputclass="form-control mr-sm-2"type="text"placeholder="Search">

</div>

</form>

</links>

<!-- Collapsible content -->

</mdb-navbar>

<!--/.Navbar-->

<app-inbox></app-inbox>

app.components.ts:

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

import { ModalService } from './modal.service';

@Component({

selector:'app-root',

templateUrl:'./app.component.html',

styleUrls: ['./app.component.scss']

})

export class AppComponent implements OnInit {

constructor(privatemodalService:ModalService) {}

openModal() {

this.modalService.showModal();

}

ngOnInit() {

}

}

inbox.component.ts:

import { Component, OnInit, ViewChild, AfterViewInit } from '@angular/core';

import { ModalDirective } from 'ng-uikit-pro-standard';

import { ModalService } from '../modal.service';

@Component({

selector:'app-inbox',

templateUrl:'./inbox.component.html',

styleUrls: ['./inbox.component.scss']

})

export class InboxComponent implements OnInit {

@ViewChild('basicModal') basicModal: ModalDirective;

constructor(privatemodalService:ModalService) { }

ngOnInit() {

this.modalService.setModal(this.basicModal);

}

}

modal.service.ts

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

import { ModalDirective } from 'ng-uikit-pro-standard';

@Injectable({

providedIn:'root'

})

export class ModalService {

yourModal:ModalDirective;

constructor() { }

setModal(modal:ModalDirective) {

this.yourModal=modal;

}

showModal() {

this.yourModal.show();

}

}

Best, Arek

is it possible to call multiple modals with this scenario ? I tried to call a another modal from a different component but it just calls the the first modal.

newtongamajr pro commented 6 years ago

Using this same approach, how can I create an array of modals. Because sometimes, we need to have many modals inside the same component. I've tried to create an array of 'ModalDirective' but didn't work at all.

Hi!

I want to do the same thing as him but I get the error: ERROR TypeError: Cannot read property 'show' of undefined at ModalService.push../src/app/modal.service.ts.ModalService.showModal

Can you please help me to solve it? I think i understand now how you can communicate between 2 components but I think that there is maybe a problem with my modal html. Do I need to define it as a modal somewhere?

The thing is: i have a component login-form (that's my modal). And I want it to open when i click on a link in an other component and when i click on an item from navbar.

Thank you in advance!

I have the same problem and I have already done everything it says

Arkadiusz Idzikowski staff commented 5 years ago

The solution from my answer is outdated, please take a look at dynamic modal documentation. This modal can be opened from any component: https://mdbootstrap.com/docs/angular/modals/basic/#dynamic

hudjoubert commented 5 years ago

      mdbWavesEffect

      Close
    </button>
    <button

      mdbWavesEffect

      Save changes
    </button>
  </div>
</div>   </div> </div>

Only show "mimimi" string

The solution from this thread may be outdated, it is now possible to create dynamic modal with ModalService. Did you follow the instructions from 'Dynamic modal' section?

https://mdbootstrap.com/docs/angular/modals/basic/#dynamic

In case of any further problems please create new thread and provide more details (full html/ts code that you use and module configuration).

Johnny Moran commented 5 years ago

But I can only use the MDBModalService from ng-uikit-pro-standard, correct? Therefore I'll have to pay to go pro, so its a clever way for you to get paid right

Arkadiusz Idzikowski staff commented 5 years ago

Dynamic modal is a free component and you can import the ModalService from 'angular-bootstrap-md' package as well. We will add this info to the documentation to avoid confusion.

I recreated that solution but I got this:

TypeError: Cannot read property 'show' of undefined at ModalService.showModalModificarEmpresa (modals.service.ts:18) at ModalModifyEmpresaComponent.showModal (modal-modify-empresa.component.ts:21) at ModalModifyEmpresaComponent_Template_button_click_2_listener (modal-modify-empresa.component.html:3) at

Arkadiusz Idzikowski staff commented 4 years ago

@Lucas Gomez
Which version of MDB Angular do you use? The workaround from this thread should no longer be needed because we added dynamic modals implementation to the library. Please take a look at the documentation: https://mdbootstrap.com/docs/angular/modals/basic/#dynamic
