- type in module ng
FormController
keeps track of all its controls and nested forms as well as the state of them, such as being valid/invalid or dirty/pristine.
Each form directive creates an instance of FormController
.
Methods
-
$rollbackViewValue();
Rollback all form controls pending updates to the
$modelValue
.Updates may be pending by a debounced event or because the input is waiting for a some future event defined in
ng-model-options
. This method is typically needed by the reset button of a form that usesng-model-options
to pend updates. -
$commitViewValue();
Commit all form controls pending updates to the
$modelValue
.Updates may be pending by a debounced event or because the input is waiting for a some future event defined in
ng-model-options
. This method is rarely needed asNgModelController
usually handles calling this in response to input events. -
$addControl();
Register a control with the form.
Input elements using ngModelController do this automatically when they are linked.
-
$removeControl();
Deregister a control from the form.
Input elements using ngModelController do this automatically when they are destroyed.
-
$setValidity();
Sets the validity of a form control.
This method will also propagate to parent forms.
-
$setDirty();
Sets the form to a dirty state.
This method can be called to add the 'ng-dirty' class and set the form to a dirty state (ng-dirty class). This method will also propagate to parent forms.
-
$setPristine();
Sets the form to its pristine state.
This method can be called to remove the 'ng-dirty' class and set the form to its pristine state (ng-pristine class). This method will also propagate to all the controls contained in this form.
Setting a form back to a pristine state is often useful when we want to 'reuse' a form after saving or resetting it.
-
$setUntouched();
Sets the form to its untouched state.
This method can be called to remove the 'ng-touched' class and set the form controls to their untouched state (ng-untouched class).
Setting a form controls back to their untouched state is often useful when setting the form back to its pristine state.
-
$setSubmitted();
Sets the form to its submitted state.
