npm install datevalidator
Testing the Package
Once the package is installed, you can run the unit tests associated with the package also using NPM.
npm test datevalidator
DateValidator at the moment provides a single method
validate method expects a year, month, and day string parameters and will validate based on such.
var date_validator = require("DateValidator"); var is_valid = date_validator.validate("2012", "12", "31"); //true
Using DateValidator Client-Side
DateValidator 1.0.7 provides a more globally accessible way of using DateValidator outside of Browserify. The algorithm is the same as of v2.0; however, the client-side instructions are different and provided with that version.
var validator = DateValidator; var is_valid = date_validator.validate("2012", "12", "31"); //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.
validate method will return
false for the following conditions:
- 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
- if the day is invalid for the provided month (i.e. Feb 31);
