What is the best way to set parameters in a modal window?

Here is how I utilize the ng2-bootstrap modal in my code snippet:

import {Component} from '@angular/core';
import {NgbModal} from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'add-customer-modal',
  template: `
    <template #test let-c="close" let-d="dismiss">
      <div class="modal-header">
        <button type="button" class="close" aria-label="Close" (click)="d('Cross click')">
          <span aria-hidden="true">&times;</span>
        </button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" (click)="c('Close click')">Close</button>
      </div>
    </template>
    <button type="button" class="btn btn-primary btn-sm" (click)="open(test)"><i class="fa fa-plus"></i> <i class="fa fa-user-o"></i></button>
  `
})
export class AddCustomerModal {

  constructor(private modalService: NgbModal) {}

  open(content) {
    this.modalService.open(content, { size: 'lg' }).result.then((result) => {
      console.log(result);
    }, (reason) => {
      console.log(reason);
    });
  }
}

I am a bit perplexed because I initially thought that the content parameter is for passing parameters to the modal. However, it seems like it's just the name the open method requires to locate the correct template.

So, how can I actually pass parameters to the modal?

If you happen to come across this information, you might find it useful. Just remember to define specific fields within your ModalComponent:

 modalTitle: string;
 client: Client;

When launching a modal, make sure to assign values to these fields as shown below.

clientModalShow() {
    const activeModal = this.modalService.open(ClientModal, { size: 'lg' });
    activeModal.componentInstance.modalTitle = 'Client Information';
    activeModal.componentInstance.client = this.selectedClient;
}

These fields can then be accessed in your template like so:

value={{client.id}}

Hopefully, this guide proves helpful.

In order to send parameters or data to the modal, a potential solution could involve utilizing the componentInstance property:

launchModal(content) {
    const modal: NgbModalRef = this.modalService.open(content, { size: 'lg' });

    (<MyComponent>model.componentInstance).info = 'hello';

    modal.result.then((result) => {
      console.log(result);
    }, (reason) => {
      console.log(reason);
    });
}

This method assumes that the componentInstance corresponds to the MyComponent type and contains a public attribute named info

If you find yourself in need of immediate data after constructing a modal, there is a more efficient approach you can take. Utilize the Angular injector technique.

Create a model for your data.

class CustomModalOptions {
  stringProp: string; 
  numberProp: number;
}

Instantiate your modal within your component:

this.modal.open(MyModal, {
  injector: Injector.create([{
    provide: CustomModalOptions, useValue: { stringProp: "foo bar", numberProp: 17 }
  }], this.injector)
});

Retrieve and handle the data in your Modal Component

@Component({ ... })
class MyModal {
  constructor(private options: CustomModalOptions) {
    console.log(this.options.stringProp);
    console.log(this.options.numberProp);
  }
}

If you're looking for guidance on incorporating Child Modal functionality, take a peek at the example provided in ng2-bootstrap's modal documentation. Simply introduce public variables to the parent component and utilize them within your modal through conventional binding methods.

For instance, in the demo template:

      <div class="modal-body">
          {{parentMessage}}
      </div>

adapt the component as shown below:

export class DemoModalChildComponent {
  @ViewChild('childModal') public childModal:ModalDirective;
  parentMessage = 'I am a child modal, opened from parent component!'; //Include this

By incorporating data from the parent component, you can reciprocate by passing data back using standard procedures.
