KR.onError()

KR.onError() allows to intercept errors before they appear.

Example of integration

An example for intercepting error messages:

https://github.com/lyra/rest-php-examples/blob/master/www/js_examples/jquery/minimalEmbeddedForm.onError.php#L70-L80

          <script type="text/javascript">
    $(document).ready(function() {
          KR.onError( function(event) {
            var code = event.errorCode;
            var message = event.errorMessage;
            var myMessage = code + ": " + message;

            try {
              /* if client answer exists, a refused transaction has been created */
              /* it's not always the case. For example, if the form is empty,    */
              /* error is raised before transaction creation                     */

After that, error messages will automatically appear in the following element, if it is present:

<div id="customerror"></div>

When several errors are generated, they are merged into one single error. The children property will contain the details of all errors:

{
    "errorCode": "CLIENT_300",
    "errorMessage": "Invalid form data",
    "children": [{
        "errorCode": "CLIENT_301",
        "errorMessage": "Invalid card number",
        "field": "pan",
        (...)
    }, {
        "errorCode": "CLIENT_302",
        "errorMessage": "Invalid expiry date",
        "field": "expiryDate",
        (...)
    }, {
        "errorCode": "CLIENT_303",
        "errorMessage": "Invalid security code",
        "field": "securityCode",
        (...)
    }],
    "detailedErrorCode": null,
    "detailedErrorMessage": null,
    (...)
}
