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.
<script> function FormController(){ this.user = { name: 'John Smith', address:{line1: '123 Main St.', city:'Anytown', state:'AA', zip:'12345'}, contacts:[{type:'phone', value:'1(234) 555-1212'}] }; this.state = /^\w\w$/; this.zip = /^\d\d\d\d\d$/; } </script> <div ng:controller="FormController" class="example"> <label>Name:</label><br/> <input type="text" name="user.name" ng:required/> <br/><br/> <label>Address:</label><br/> <input type="text" name="user.address.line1" size="33" ng:required/> <br/> <input type="text" name="user.address.city" size="12" ng:required/>, <input type="text" name="user.address.state" size="2" ng:required ng:validate="regexp:state"/> <input type="text" name="user.address.zip" size="5" ng:required ng:validate="regexp:zip"/><br/><br/> <label>Phone:</label> [ <a href="" ng:click="user.contacts.$add()">add</a> ] <div ng:repeat="contact in user.contacts"> <select name="contact.type"> <option>email</option> <option>phone</option> <option>pager</option> <option>IM</option> </select> <input type="text" name="contact.value" ng:required/> [ <a href="" ng:click="user.contacts.$remove(contact)">X</a> ] </div> <hr/> Debug View: <pre>user={{user}}</pre> </div>
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[name=user.address.zip]').attr('className')) .not().toMatch(/ng-validation-error/); using('.example').input('user.address.zip').enter('abc'); expect(using('.example').element(':input[name=user.address.zip]').attr('className')) .toMatch(/ng-validation-error/); }); it('should validate state', function(){ expect(using('.example').element(':input[name=user.address.state]').attr('className')) .not().toMatch(/ng-validation-error/); using('.example').input('user.address.state').enter('XXX'); expect(using('.example').element(':input[name=user.address.state]').attr('className')) .toMatch(/ng-validation-error/); });
