Questions tagged [angularjs-ng-model]

The ngModel directive in AngularJS binds an input, select, textarea (or custom form control) to a property on the scope using NgModelController, which is created and exposed by this directive.

ngModel is responsible for:

  • Instantiating the ngModelController
  • Binding the view into the model, which other directives such as input, textarea or select require.
  • Providing validation behavior (i.e. required, number, email, url).
  • Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
  • Setting related CSS classes on the element (ng-valid, ng-invalid, ng-dirty, ng-pristine, ng-touched, ng-untouched) including animations.
  • Registering the control with its parent form.
  • Formatters, Parsers and View change listeners
