Cookbook: Form

Work in Progress This page is currently being revised. It might be incomplete or contain inaccuracies.

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/);
  });
