Custom Bootstrap validation on form element

I am collecting an ABN (Australian Business Number) on a registration form. I have written some javascript that does validation based on the ABN validation rule here:
function validateABN (abnNumber) {
var weights = [10, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19];
var result = false;
if (abnNumber.length === 11) {
var sum = 0;
var weight;
for (var index = 0; index <= weights.length - 1; index++) {
weight = weights[index];
digit = abnNumber[index] - (index ? 0 : 1);
sum += weight * digit;
}
result = sum % 89 === 0;
}
return result;
}
console.log(validateABN('43154365778'));
The form field name is: CompanyABNACN
It is a bootstrap form. I'm a little familiar with bootstrap but not to the point where I can add custom form field validation on a form element. I want an error message to be displayed "Invalid ABN format" if the javascript validation fails.
I have searched google and within the stack overflow forums and have not been able to find an example similar to mine or I have found really complicated examples I'm not able to understand.
Would someone please explain to me how to incorporate this custom function into validation on my registration form please.

You didn't specify when the validation should occur, e.g. as the user is entering the ABN number or when they submit the form. Assuming the former, you can do the following:
Add an 'input' event listener to the ABN input field so that it validates every time the user enters something in that field:
<input name="CompanyABNACN" type="text" id="CompanyABNACN" placeholder="" class="form-control required is-invalid" oninput="do_validate();" />
(You can also use jQuery to add an event listener rather than doing it inline as in my example above.)
Your validation function should look something like this:
function do_validate() {
if ( validateABN( $('input#CompanyABNACN').val() ) ) {
$( '.invalid-feedback' ).hide();
$('input#CompanyABNACN').removeClass( 'is-invalid' )
} else {
$( '.invalid-feedback' ).show();
$('input#CompanyABNACN').addClass( 'is-invalid' )
}
}

You need to add "is-invalid" class to the input to invalidate for ABN via javascript.
<div class="col-md-3 mb-3">
<label for="ABNnumber">Zip</label>
<input type="text" class="form-control" id="ABNnumber" name="ABNnumber" required>
<div class="invalid-feedback">
Please provide a valid ABN.
</div>
</div>
Your javascript should be sth like this
$("form#abnFormSubmit").on("submit", function(e){
e.preventdefault;
var isAbnValid = validateABN($("#ABNnumber").val());
if(!isAbnValid){
$("#ABNnumber").addClass("is-invalid");
}
else{
$("#ABNnumber").removeClass("is-invalid");
}
})

Why the form is not setting after using parsley().reset(); and still showing validators

I am Using ParsleyJs to validate below shown form, I have been trying to reset the form by calling Reset() function on click of Reset button and i have validated the form using isValid() on form submission and not from the data-parsley-validate in form. After using (#formid).parsley().reset(); in Reset() function the form resets all it's fields but still shows the validator saying "this field is required", i have not found any soution in ParsleyJs documentation.

</form>
Below shown is the Reset function
function Reset() {
$("#Person")[0].reset();
$('#Person').parsley().reset();
}

Your button is a submit button! So it validates again your form after the reset...
To make it not a submit button use <button type="button" ...>.
Alternatively you could return false in your onclick, or change it to a <div>, or put it outside the form.

Validation error An invalid form control with name='' is not focusable

I had a html form with set of input fields for each of which I am giving required="true" for validation. But when I click on submit after entering the mandatory fields it is give an error:
An invalid form control with name='' is not focusable
I know if we use novalidate to the form I wont get that error, but my validation wont work. How can I make my validation work without error?

Disable 'Continue' button

So I have the following fields, basically to create an account. This is just for a prototype. I was wondering how to disable the continue button and only enable the button once all fields have been completed. I have seen this can be done using jQuery and forms, but as this isn't really a form it doesn't work correctly. I understand it may be easier using but I have to use all of the fields there as they are shown. So basically is there a way for it work with only using what I already have?

You may not have nested forms.
Once fixed, you can just check if the fields are empty or not after an input changes.
$('#continue').click(function(e){
e.preventDefault();
if(checkFields())
$('#form1').find('form').submit();
return false;
});
function checkFields() {
$('#form1 input').each(function(){
if($(this).val() == '')
return false;
else
return true;
});
}

Jquery Validation plugin not validating entire form

I am trying to validate a form with the jQuery validation plugin. However, I am only getting the validation to work for 1 of the inputs. Any ideas?

The validation framework used name attribute, you have not specified it
<input type="text" class="form-control" id="driverFirst" name="driverFirst" placeholder="First Name" required/>
