Validating dom technology and dating relationships
Parsley adds its share of classes and elements, to ease nice UI validation result display.By default, it will add Field instances have low level methods to add, update & remove manage error messages.You are strongly encouraged to customize them in your own stylesheets, but here is the "standard" Parsley css file that is used here on the documentation and examples, if you want to use it to bootstrap your projects with Parsley.Parsley comes with various error messages for its built-in validators.
Yet, despite being available in the latest version of all major browsers, constraint validation is a topic largely relegated to presentations and demos.
It helps you provide your users with feedback on their form submission before sending it to your server.
It saves you bandwidth, server load and it saves time for your users.
That's why Parsley is here: to let you define your general form validation, implement it on the backend side, and simply port it frontend-side, with maximum respect to user experience best practices.
For performance reasons, Parsley does not use j Query events, but the API to listen to events is very similar: By default, all 2xx ajax returs are considered valid, all others failure.
