AngularJS form Directive
AngularJS form Directive
AngularJS is used to change the default behavior of the form element. In AngularJS, forms are given certain new properties. These properties are described by the current state in which the form is present.
Form States are:-
- $pristine - No fields have been modified yet.
- $dirty - One or more have been modified
- $invalid - The form content is not valid
- $valid - The form content is valid
- $submitted - The form is submitted
All of these properties above have boolean values i.e, true or false.
In AngularJS, forms have given certain classes to style it when the state changes.
Form classes are:-
- ng-pristine - No fields have not been modified yet
- ng-dirty - One or more fields have been modified
- ng-valid - The form content is valid
- ng-invalid - The form content is not valid
- ng-valid-key - One key for each validation. Example: ng-valid-readonly.
- ng-invalid-key Example: ng-invalid-required.
