How pass data from ModalService into component

Question

I'm trying to use ngx-bootstrap-modal to pass data from a modal service into a modal component. The examples show this:

this.modalService.show(ModalContentComponent, {initialState});

But it doesn't show how the ModalContentComponent actually consumes that state. I've played around in a debugger and I never see my component getting that data.

How do I access it from the component?

Solution 1

Here, in parentComponent where initialState data is being sent using config param in modalService.show:

const initialState = {
      data: "Test Data"
    };
    this.modalService.show(ModalContentComponent, {initialState});

Access the data in ModalContentComponent by simply defining exact same named variable, i.e., data: string; You will be able to access value of data in ModalContentComponent.html and ModalContentComponent.ts.

Solution 2

You can also use the BsModalRef content Like

my-modal.component.ts

export class MyModalComponent {
  public myContent;
  constructor(){}
}

calling your modal from some other component

import { BsModalService, BsModalRef } from 'ngx-bootstrap/modal';
...
    public modalRef: BsModalRef;

    constructor(public modalService: BsModalService){}

    public openModal() {
       this.modalRef = this.modalService.show(MyModalComponent);
       this.modalRef.content.myContent= 'My Modal Content';
    }
...

Solution 3

At the stage of creating a modal, every property from initialState is copied to the component that you pass as a modal content.

For example, if your initialState looks like this:

const initialState = {
   list: [
     'Open a modal with component',
     'Pass your data',
     'Do something else',
     '...',
     'PROFIT!!!'
   ],
   title: 'Modal with component',
   closeBtnName: 'Close'
 };

Then all these properties are copied to your modal content component and they're accessible there and you can use them in your template or ngOnInit as usual. In general, these properties are like @Input.

Since I can't yet comment on IlyaSurmay's answer...his solution works in 2.0.2 (but not in 2.0.0).

how to pass the id? i'm getting undefined this.modalRef = this.modalService.show(ConfirmationModalComponent, { initialState }); this.modalRef.content.itemId = '2'; ngOnInit(): void { console.log(this.itemId); }

Properties of a modal component that were set after modalService.show() won't be available in ngOnInit. If you want to get access to this data in ngOnInit, use initialState as I shown above

i had version 1.9.3 and did not work. after upgrading ngx-bootstrap to version 2.0.5 it started working

Just to add something that I struggled with. After showing the modal using the service modalService.show(MyModalComponent, initialState) then the initialState can be injected in MyModalComponent's constructor like this constructor(modal: BsModalRef, options: ModalOptions)
