Custom Validation in Parsley.js

Which parsley.js functions do I need to call to custom validate with javascript?

The reason I ask this is because I defined the following Assert Array in the back end and want to reuse this in the front end: [ new Assert().Length( { min: 33, max: 25 } ), new Assert().NotBlank() ]

Thank you,

You'll find here the documentation on how to define your custom validators for Parsley.

What you are trying to do may look something like that:

<script type="text/javascript">
window.ParsleyConfig = {
  validators: {
    myvalidator: {
      fn: function (value) {
        return Validator.validate(value, [ new Assert().Length( { min: 33, max: 25 } ), new Assert().NotBlank() ]);
      },
      priority: 32
    }
  },
  i18n: {
    en: {
      myvalidator: 'Your field is invalid, or some different message'
    }
  }
};
</script>

Note: why defining these two asserts? NotBlank() is redundant with previous one, because a Blank field would obviously be wrong, its length being inferior to 33 min length. I don't really see the point to add NotBlank() here :)

Best
