Angular binding allows for seamless connection of objects to input fields

Trying to establish a connection between a Company object in my component and the view has proved to be more challenging than expected. While I didn't encounter any issues doing this in AngularJS, attempting it in Angular 2 resulted in an error.

View

<input type="text" class="form-control" [(ngModel)]="company.name" 
    placeholder="Company Name" required>
<input type="text" class="form-control" [(ngModel)]="company.address1" 
    placeholder="Address Line 1" id="address1" required>
<button class="btn btn-primary pull-right next-btn" (click)="show()">Next</button>

Component:

company: Company;

constructor(
  private router: Router
 ) { }

ngOnInit() { }

show() {
  console.log(this.company);
}

Error Message:

TypeError: Cannot read property 'name' of undefined

Answer №1

When utilizing ngModel outside of a form, it is essential to establish options with

[ngModelOptions]="{standalone: true}"
. Conversely, if you have a form in place, be sure to assign the name attribute to each control.

Answer №2

If you are experimenting with Template Driven forms, consider exploring Reactive Forms by visiting the link below:

Best of luck on your journey!

Here is a code snippet for reference to (Template Driven Form).

<code>
import { Component, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { FormsModule } from '@angular/forms';

@Component({
  selector: 'app',
  template: `
    <form #f="ngForm" (ngSubmit)="onSubmit(f.value)">
      <div>Username:        <input type="text"     name="username" ngModel></div>
      <div>SSN:             <input type="text"     name="ssn"      ngModel></div>
      <div>Password:        <input type="password" name="password" ngModel></div>
      <div>Confirm password: <input type="password" name="pconfirm"  ngModel></div>
      <button type="submit">Submit</button>
    </form>
  `
})
class AppComponent {
  onSubmit(formData) {
    console.log(formData);
  }
}

@NgModule({
  imports     : [ BrowserModule, FormsModule ],
  declarations: [ AppComponent ],
  bootstrap   : [ AppComponent ]
})
class AppModule {}

platformBrowserDynamic().bootstrapModule(AppModule);
</code>
