AngularJS Form Directives

AngularJS provides form validations by monitoring the state of the form and the input fields. It notifies the user about the current state of the form. Following are some of the directives used for form validations.

• ng-pattern - Does pattern validation. Often used for text based input controls.
• ng-minlength / ng-maxlength - Does the min/max length validation checks.
• ng-required - Sets the 'required' attribute on the element if the AngularJS expression inside ngRequired evaluates to true.
• ngsubmit - Enables binding AngularJS expressions to onsubmit events.
