Forms in AngularJS provides data-binding and validation of input controls.

Input Controls

Input controls are the HTML input elements:

• input elements
• select elements
• button elements
• textarea elements

Data-Binding

It can also be referred to elsewhere in the application:

Radiobuttons

Bind radio buttons to your application with the ng-model directive.

Radio buttons with the same ng-model can have different values, but only the selected one will be used.

Example

Display some text, based on the value of the selected radio button:

<form>
  Pick a topic:
  <input type="radio" ng-model="myVar" value="dogs">Dogs
  <input type="radio" ng-model="myVar" value="tuts">Tutorials
  <input type="radio" ng-model="myVar" value="cars">Cars
</form>

The value of myVar will be either dogs, tuts, or cars.

Selectbox

Bind select boxes to your application with the ng-model directive.

The property defined in the ng-model attribute will have the value of the selected option in the selectbox.

 Example

Display some text, based on the value of the selected option:

<form>
  Select a topic:
  <select ng-model="myVar">
    <option value="">
    <option value="dogs">Dogs
    <option value="tuts">Tutorials
    <option value="cars">Cars
  </select>
</form>

The value of myVar will be either dogs, tuts, or cars.

An AngularJS Form Example

First Name:

Last Name:


RESET

 

form = {"firstName":"John","lastName":"Doe"}

master = {"firstName":"John","lastName":"Doe"}

Application Code

<div ng-app="myApp" ng-controller="formCtrl">
  <form novalidate>
    First Name:<br>
    <input type="text" ng-model="user.firstName"><br>
    Last Name:<br>
    <input type="text" ng-model="user.lastName">
    <br><br>
    <button ng-click="reset()">RESET</button>
  </form>
  <p>form = {{user}}</p>
  <p>master = {{master}}</p>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope) {
  $scope.master = {firstName: "John", lastName: "Doe"};
  $scope.reset = function() {
    $scope.user = angular.copy($scope.master);
  };
  $scope.reset();
});
</script>

The novalidate attribute is new in HTML5. It disables any default browser validation.

Example Explained

The ng-app directive defines the AngularJS application.

The ng-controller directive defines the application controller.

The ng-model directive binds two input elements to the user object in the model.
