Validation snippets

You can use the following Javascript funcions to validate some of the mandatory fields requested in your checkout.

phone_number_validation.js
function validatePhoneNumber(phoneNumber){
const re = /^\([1-9]{2}\) (?:[2-8]|9[1-9])[0-9]{3}\-[0-9]{4}$/;
return re.test(String(phoneNumber));
}
zipcode_validation.js
function validateZipcode(zipcode){
const re = /[0-9]{8}/;
return re.test(String(zipcode));
}
cpf_cnpj_length_validation.js
var options = {
onKeyPress: function (cpf, ev, el, op) {
var masks = [000.000.000-000,00.000.000/0000-00];
