機能するはずのサンプルを次に示します。

2 つのパスワード フィールドに焦点を当てます。クライアント側の検証を行うものに関して、Zend_Form_Element 属性を除外します。
->addElement('PasswordTextBox', 'password_2_', array(
// strictly serverside, only accepts alphanumerical pwds lengths 6 through 20
'validators' => array(
'Alnum',
array('StringLength', false, array(6, 20)),
),
// widget id
'id' => 'passwordconfirm_register1',
// both client-/server-side - triggers 'emptyMessage' validation
'required' => true,
// runs with the form.validate() and events onblur, oninit, onkeypress
// if ! dijit.get("value").match(dijit.regExp) show 'invalidMessage'
// this example matches the serverside reqs
'regExp' => "^([a-zA-Z0-9_\-!-=]){6,32}$",
// shown with form.validate(), dijit.validate() and input.blur() if regExp is not a match against value
'invalidMessage' => 'Password musts: 6 to 32 chars and only numbers, letters or amongst [ _-!"#%&/()=]',
))
2 番目の pwd フィールド、属性は同じですが、バリデーターが異なります
->addElement('PasswordTextBox', 'password_2_', array(
// strictly serverside, only accepts alphanumerical pwds lengths 6 through 20
'validators' => array(
array('identical',false,array('token'=>'password'))
),
// widget id
'id' => 'passwordconfirm_register2',
'required' => true,
// in theory, we would define 'validator' in programmatic construct of
// the validationtextbox. but this will not work with the way Zend handles dojo
// 'validator' => 'function(value, constraints) { return "BAD PRACTICE" }'
));
// add javascript code to run onload and to extend the 'register2' properly
$this->getElement()
->getView()
->headScript()
->appendFile($baseUrl . '/js/Validator.js');
現在のところ、passwordconfirm_register2 ウィジェットでクライアント側で検証されるのは「必須」のみです。上記の行の「悪い習慣」に関してマークアップ ファクトリが行うことを修正しましょう。その行を削除し、代わりに以下を含む JavaScript コードを追加します。
// file: baseUrl/js/Validator.js
dojo.addOnLoad(function() {
dijit.byId('passwordconfirm_register2').validate = function(value, constraints) {
if(dijit.byId('passwordconfirm_register1').get("value") != value) {
this.invalidMessage = "Passwords are not identical";
return false;
}
return true
});
});
