An error message pops up in Angular form, stating that "_co.service is not defined."

Having trouble sending data to a firebase project from an angular form and encountering a specific error.

This snippet shows the HTML part of the component containing the form:

<form #form="ngForm" autocomplete="off"> 

              <div class="form-row">
                <div class="input-group form-group-no-border col-lg-6">
                  <input type="text" name=FirstName #FirstName="ngModel" [(ngModel)]="sevice.formData.FirstName" class="form-control" placeholder="First Name..." required />
                </div>
                <div class="input-group form-group-no-border input-lg col-lg-6">
                  <input type="text" name=LastName #LastName="ngModel" [(ngModel)]="sevice.formData.LastName" class="form-control" placeholder="Last Name..." required />
                </div>
              </div>

              <div class="input-group form-group-no-border input-lg">
                <input type="text" name=Email #Email="ngModel" [(ngModel)]="sevice.formData.Email" class="form-control" placeholder="Email Address..." required />
              </div>
              <div class="input-group form-group-no-border input-lg">
                  <input type="password" name=Password #Password="ngModel" [(ngModel)]="sevice.formData.Password" placeholder="Password..." class="form-control" required />
              </div>
              <div class="input-group form-group-no-border input-lg">
                <input type="password" placeholder="Re-Enter Password..." class="form-control" required />
              </div>

              <div class="footer text-center">
                  <button type="submit" class="btn btn-block btn-round btn-lg btn-info"> Get Started</button>
              </div>  

            </form>

This is the TypeScript file for that component:

import { Component, OnInit } from '@angular/core';
import { AuthenticationService } from '../Shared/authentication.service';
import { NgForm } from '@angular/forms';

@Component({
  selector: 'app-signup',
  templateUrl: './signup.component.html',
  styleUrls: ['./signup.component.scss']
})
export class SignupComponent implements OnInit {

  constructor(private service : AuthenticationService) { }

  ngOnInit() {
    this.resetForm();
  }

  resetForm(form? : NgForm){
    if(form!=null){
      form.resetForm();
      this.service.formData={
        FirstName : '',
        LastName : '', 
        Email : '',
        Password : '',
      }
    }
  }

}

Below is the code for the service:

import { Injectable } from '@angular/core';
import { Authentication } from './authentication.model'; 

@Injectable({
  providedIn: 'root'
})
export class AuthenticationService {
  formData :  Authentication;

  constructor() { }
}

Finally, here is the model class for the service:

export class Authentication {
    FirstName : string ;
    LastName : String ;
    Email : string ;
    Password : string ;
}

If there's any confusion, I would appreciate it if someone could assist in resolving this issue.

Answer №1

Upon examining the constructor of your component, it appears that you have set the service as a private variable. As a result, accessing it from the template may not be possible unless it is changed to public. This is the first issue to address. Furthermore, upon reviewing the error message, it becomes evident that there is a typographical error in the template where "service" is spelled as "sevice". Correcting these two aspects should resolve the problem.

In addition to the above points, it has been mentioned in the comments that exposing the service in such a manner is not considered good practice. It is recommended to gather the necessary data (such as email and password) within the component itself and then pass it to the service using an appropriate trigger like a click event.
