There may be something in the marketplace, but I would like to know more about how the validation scripts included with Magento work first, before I consider purchasing a different solution. There seems to be a validation.js file in Magento already. Does anyone know where this is used, and if this file could be modified to add validation rules for a ZIP code?
I saw this "somewhere," and was hoping I could use it. It came from a validation.js file, but the file does not look like the validation.js file currently on our site. Maybe it's an example of how someone modified the file I am seeing?
"validate-zip-us": [
function (v) {
return $.mage.isEmptyNoTrim(v) || /(^\d{5}$)|(^\d{5}-\d{4}$)/.test(v);
},
'Please enter a valid zip code (Ex: 90602 or 90602-1234).'
],
