jQuery.validator.addMethod
.$(document).ready()
as at that point it's too latejQuery.validator.unobtrusive.parse
or jQuery.validator.unobtrusive.parseElement
on elements added dynamically after the initial page load.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
