Magento 1.9 - Add custom zipcode validation on Home page

Question

Validate a zip code field on a home page popup in Magento 1.9 style might be using jquery button click.

Answer 1

If you use the standard Magento form validation you can do this by adding the css class validate-zip to your form field. That will pass the form input to the corresponding method in validatation.js.

I hope that helps.
