Utilizing AngularJS to invoke an ng-controller within a nested controller structure

Take a look at this sample code from the cshtml file:

<div>
    <button type="button" ng-click="recalcButton()">Recalc Button</button>
</div>
<div ng-controller="appealPartialController">
    <div ng-include="'/Partials/appealsPartial.html'"></div>
</div>

I am trying to figure out how to refresh the data in the appealPartialController when the recalcButton is clicked. If anyone has any recommendations, documentation, or JavaScript examples to share, I would really appreciate it!

Answer №1

After conducting extensive research and receiving inspiration from a sudden stroke of genius, I was able to discover a resolution by making use of the inherent $scope feature in angularJS and triggering the load function from the main component.

$scope.$$childHead.$$nextSibling.loadAppealModel($scope.claimID);

Answer №2

To implement shared parameters, begin by creating a service as shown below:

import { Injectable, EventEmitter } from '@angular/core';
import { Subscription } from 'rxjs/internal/Subscription';

@Injectable({
  providedIn: 'root'
})
export class SharedParamsService {

  invokeFirstComponentFunction = new EventEmitter();
  subsVar: Subscription;

  constructor() { }

  onUpdateEnv(key, val) {
    var toEmit = [key, val]
    this.invokeFirstComponentFunction.emit(toEmit);
  }
}

Once the service is set up, you can trigger an event when a button is clicked in your component:

recalcButton(){
    this.sharedParams.onUpdateEnv("btn", this.jobObj.name);
}

Next, in the component where you want to update based on the button click, subscribe to the emitter in the shared service:

 this.sharedParams.subsVar = this.sharedParams.
     invokeFirstComponentFunction.subscribe((emitted) => {
        if (emitted[0] == "btn") {
            this.ngOnInit();
        }
      });

While using key-value pairs is optional, it allows for flexibility in handling multiple events or variables.
