@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.
it('should show debug', function() {
expect(binding('user')).toMatch(/John Smith/);
});
it('should add contact', function() {
using('.example').element('a:contains(add)').click();
using('.example div:last').input('contact.value').enter('you@example.org');
expect(binding('user')).toMatch(/\(234\) 555\-1212/);
expect(binding('user')).toMatch(/you@example.org/);
});
it('should remove contact', function() {
using('.example').element('a:contains(X)').click();
expect(binding('user')).not().toMatch(/\(234\) 555\-1212/);
});
it('should validate zip', function() {
expect(using('.example').
element(':input[ng\\:model="user.address.zip"]').
prop('className')).not().toMatch(/ng-invalid/);
using('.example').input('user.address.zip').enter('abc');
expect(using('.example').
element(':input[ng\\:model="user.address.zip"]').
prop('className')).toMatch(/ng-invalid/);
});
it('should validate state', function() {
expect(using('.example').element(':input[ng\\:model="user.address.state"]').prop('className'))
.not().toMatch(/ng-invalid/);
using('.example').input('user.address.state').enter('XXX');
expect(using('.example').element(':input[ng\\:model="user.address.state"]').prop('className'))
.toMatch(/ng-invalid/);
});
# Things to notice
* The user data model is initialized {@link api/angular.directive.ng:controller controller} and is
available in
the {@link api/angular.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/angular.widget.input input widgets} simply refer to the model and are data-bound.
* The inputs {@link guide/dev_guide.forms 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.
