Parsley.JS - Get an error list using callback

问题

In my project I don't want to display HTML errors, but throw an alert() with list of errors on formSubmit. I guess this should be done somehow by using listeners:onFormSubmit callback, however none of passed variables does not contain "clean" version of errors. Parsley documentation also lacks of this feature.

As of version 2.8.0, you can access the error messages via fieldInstance.getErrorsMessages()

Example:

<form method="post" id="myForm">
    <input type="text" name="phone" value="" class="required" data-parsley-type="integer" />
    <input type="submit" value="Go">
</form>

<script type="text/javascript">
    $(document).ready(function() {
        $("#myForm").parsley();

        window.Parsley.on('field:error', function(fieldInstance){
            // get messages & alert
            var arrErrorMsg = fieldInstance.getErrorsMessages();
            var errorMsg = arrErrorMsg.join(';');
            alert(errorMsg);

            // get name of the input with error
            alert(fieldInstance.$element.attr('name'));
        });
    });
</script>

Also take a look at the following question Display parsley errors in bootstrap tooltip

To solved warning

parsley.min.js:16 Parsley's pubsub module is deprecated; use the 'on' and 'off' methods on parsley instances or window.Parsley

Try this

window.Parsley.on('field:error', function () {
                // This global callback will be called for any field 
                //  that fails validation.
                console.log('Validation failed for: ', 
          this.$element.attr('name'));
            });
