Tips for updating parameters that are defined in a controller within a promise

Currently, I am developing a single page application using Angular and TypeScript. I am facing an issue with updating the parameter value (_isShowFirst) of the controller inside a promise function. It seems like nothing is recognized within the promise block. The service function returns a Promise as well. Below is my controller code:

module CreditCardActivation {
    'usestrict';

export class CreditCardActivationController {

    public _isShowFirstStep: boolean;
    public _isShowSecondStep: boolean;
    public _errorMessage: string;


    constructor() {
        this._isShowFirstStep = true;
        this._isShowSecondStep = false;
    }



    activate = () => {

        this.ActivationService.activate(somedata).then((result) => {
          //-------Problem is here ----------//
    this._isShowFirst = true
        });


    }
}
angular.module('Activation').controller('ActivationController', ActivationController)

}

This is the activation function in my service:

activate = (data:ActivationRequest): ng.IPromise<ActivationResponse> =>{
  var response = this.httpService.get("someurl").then({
  return JSON.parse(JSON.stringify(response.data));
});
return (response);
}

Do you have any idea on how to solve this issue? Any help is appreciated. Thank you!

Answer №1

please.activateService.actuate(data)

I cannot find any mention of activateService being injected into the main component. It is likely that you are receiving an error due to it being undefined.
