require.js
Require.js permite cargar los guiones de forma asíncrona. Para más información sobre el funcionamiento de require.js, consulte:
Ejemplo de integración
Para cargar la biblioteca del formulario incrustado requirejs , agregue el siguiente código en la sección de su página:
https://github.com/lyra/rest-php-examples/blob/master/www/js_examples/requirejs/minimalEmbeddedForm.php#L53-L77
<script type="text/javascript">
// RequireJS Configuration
var requirejs = {
paths: {
krypton: '<?php echo $client->getClientEndpoint();?>/static/js/krypton-client/V4.0/stable/kr-payment-form.min',
kryptonTheme: '<?php echo $client->getClientEndpoint();?>/static/js/krypton-client/V4.0/ext/classic'
}
};
</script>
<script src="https://requirejs.org/docs/release/2.3.6/minified/require.js" type="text/javascript"></script>
<!-- Javascript form library loaded with requirejs-->
<script type="text/javascript">
requirejs(['krypton', 'kryptonTheme'], function() {
// use KR global variable to manipulate the form library
// for example here, we intercept the error message
KR.onError( function(event) {
var code = event.errorCode;
var message = event.errorMessage;
var myMessage = code + ": " + message;
console.log(myMessage);
});
});
</script>require.js cargará de forma asíncrona el cliente JavaScript (path krypton) y el tema clásico (path kryptonTheme).
Luego, en la sección body , agregue el formulario de pago:
https://github.com/lyra/rest-php-examples/blob/master/www/js_examples/requirejs/minimalEmbeddedForm.php#L85-L102
<!-- payment form with configuration directives -->
<div class="kr-embedded" kr-public-key="<?php echo $client->getPublicKey();?>"
kr-post-url-success="/paid.php"
kr-post-url-refused="/refused.php"
kr-form-token="<?php echo $formToken;?>">
<!-- payment form fields -->
<div class="kr-pan"></div>
<div class="kr-expiry"></div>
<div class="kr-security-code"></div>
<!-- payment form submit button -->
<button class="kr-payment-button"></button>
<!-- error zone -->
<div class="kr-form-error"></div>
</div>Observe que las directivas de configuración (**kr-public-key**, ...) se definen en el div del formulario (clase **kr-embedded**), a diferencia de una integración clásica.
