Configure Parsley using Javascript, not html data attributes

问题

How do I configure Parsley using javascript, not html data attributes?

The documentation examples show how to configure the Parsley form instance and some global field options using JS, but I want to be able to add and configure all field instances that way too. I don't want to use the html data attributes. Is that possible?

I think this question is driving at the same problem, How to use ParsleyJS 2.* using javascript and not data attributes, but it's not 100% clear.

@kim-prince Hope this helps

<form id="myForm">
  <input id="number" placeholder="Number" />
  <input type="submit" />
</form>

<script>
$('#myForm').parsley();
$("#number").parsley().addConstraint('type','number');
$("#number").parsley().addConstraint('minlength',2);
$("#number").parsley().addConstraint('required');
</script>
