FormValidation is one of the best validation library for JavaScript. For more info see the official siteand the Github repository.

Basic Inputs Example

Here's an example of multiple basic inputtypes within a formthat has FormValidation attached to it.

All input types require the nameattribute to bind the input field for validation.

FormValidation is best used together with our integrated SweetAlert2. For more info, please visit the official website.
