Java script for validating date


The validation constraints can be declared in JSON and shared between clients and the server. One thing that is a bit unorthodox is that most validators will consider undefined values (,) valid values.So for example adding a constraint of at least 6 characters will be like saying If the attribute is given it must be at least 6 characters.The project can be found on Git Hub where you can also find our issue tracker.There is also a Travis project used for testing, a Coveralls project used to code coverage as well as the annotated source.You can tell to use any A compatible promise implemention like this: There are already many validation libraries out there today but most of them are very tightly coupled to a language or framework.

There are no required external dependencies at all!Though for the datetime and date validator to you need to specify a parse and format function and for that you most likely will want to use a library, is highly recommended.If you want to use async validation you need to use a runtime that supports Promises.Sometimes it's nice to be able validate field differently depending on the input itself.allows the validators object and validator options to be a function that should return the constraints/options: Validates the attributes object against the constraints.This function takes a value and checks it against a regular expression to see if it is in the correct format (DD/MM/YY).
