-@ngdoc overview
-@name Cookbook: Form
-@description
-
-A web application's main purpose is to present and gather data. For this reason Angular strives
-to make both of these operations trivial. This example shows off how you can build a simple form to
-allow a user to enter data.

-<doc:example>
- <doc:source>
- <script>
- function FormController($scope) {
- var user = $scope.user = {
- name: 'John Smith',
- address:{line1: '123 Main St.', city:'Anytown', state:'AA', zip:'12345'},
- contacts:[{type:'phone', value:'1(234) 555-1212'}]
- };
- $scope.state = /^\w\w$/;
- $scope.zip = /^\d\d\d\d\d$/;
-
- $scope.addContact = function() {
- user.contacts.push({type:'email', value:''});
- };
-
- $scope.removeContact = function(contact) {
- for (var i = 0, ii = user.contacts.length; i < ii; i++) {
- if (contact === user.contacts[i]) {
- $scope.user.contacts.splice(i, 1);
- }
- }
- };
- }
- </script>
- <div ng-controller="FormController" class="example">
-
- <label>Name:</label><br>

-# Things to notice
-
-* The user data model is initialized {@link api/ng.directive:ngController controller} and is
- available in the {@link api/ng.$rootScope.Scope scope} with the initial data.
-* For debugging purposes we have included a debug view of the model to better understand what
- is going on.
-* The {@link api/ng.directive:input input directives} simply refer
- to the model and are data-bound.
-* The inputs validate. (Try leaving them blank or entering non digits in the zip field)
-* In your application you can simply read from or write to the model and the form will be updated.
-* By clicking the 'add' link you are adding new items into the `user.contacts` array which are then
- reflected in the view.
