Using Luhn Client-Side
In addition to being usable as a Node.js module, the validator can also be used client-side in the user's web browser. When you install
While you can copy the
date-validator.js file from the module's installation directory under
node_modles, an automated script has been provided to assist you in this copy process and to make it more streamlined. To do a client-side install, simply type the following
npm run-script DateValidator client-install
Once you run that command, you'll be prompted to provide the path to which to install
var validator = DateValidator;var is_valid = date_validator; //true
By default, the DateValidator module places itself into the global scope in the browser. If you would prefer to NOT have it be directly attached to the
window object, you can add your own
namespace at the top of the date-validator.js file.

- if any parameter is
- if any parameter is not numeric
- if any parameter is less than or equal to (<=) 0
- if the month is greater than 12
