The array must contain objects ... messages. If not present in the object, the name parameter will be used. Example: If your field name is user, you may choose to use a display of "Username."...

Without this setting, some malicious URLs cannot be distinguishable from a valid URL with authentication information. require_host - if set to false isURL will not check if host is present in the URL. require_port - if set to true isURL will check if port is present in the URL. require_valid_protocol - isURL will check if the URL's protocol is present in the protocols option. allow_underscores - if set to true, the validator will allow underscores in the URL. host_whitelist - if set to an array of strings or regexp, and the domain matches none of the strings defined in it, the validation fails

In express.js, this is parsed from the request path and matched with route definition path, but it can really be anything meaningful coming from the HTTP request. req.query: the portion after the ? in the HTTP request's path, parsed as an object from query parameter name to value. One example library that works out of the box with express-validator is Restify.

validate.js is a lightweight JavaScript form validation library inspired by CodeIgniter. ... var validator = new FormValidator('example_form', [{ name: 'req', display: 'required', rules: 'required' }, { name: 'alphanumeric', rules: 'alpha_numeric' }, { name: 'password', rules: 'required' }, { name: 'password_confirm', display: 'password confirmation', rules: 'required|matches[password]' }, { name: 'email', rules: 'valid_email' }, { name: 'minlength', display: 'min length', rules: 'min_length[8]' }, { names: ['fname', 'lname'], rules: 'required|alpha' }], function(errors) { if (errors.length > 0) { // Show the errors } });

See https://github.com/ansman/validate.js/releases/tag/0.13.1 for the changelog.

Validate.js includes smart defaults and works right out of the box. But if you want to customize things, it also has a robust API that provides multiple ways for you to adjust the default options and settings. You can pass options and callbacks into Validate through the init() function:

Include jQuery and the plugin on a page. Then select a form to validate and call the validate method. <form> <input required> </form> <script src="jquery.js"></script> <script src="jquery.validate.js"></script> <script> $("form").validate(); ...

Simple form validation with oops concept in JavaScript.

const validation = new JustValidate('#form'); validation .addField('#name', [ { rule: 'minLength', value: 3, }, { rule: 'maxLength', value: 30, }, ]) .addField('#email', [ { rule: 'required', errorMessage: 'Email is required', }, { rule: 'email', ...

Returns the errors object from the last validation (sync only). // Example output: { email: 'WRONG_EMAIL', password: 'TOO_SHORT', address: { zip: 'NOT_POSITIVE_INTEGER' } }

A simple program In js for form validations.

December 12, 2021 - Validate.js provides a declarative way of validating javascript objects.

var validatorClasses = { field : 'field', // class for each input wrapper alert : 'alert', // call on the alert tooltip bad : 'bad' // classes for bad input }; validator = new FormValidator(null, {classes:validatorClasses}); // or validator = new FormValidator(); validator.settings.classes.bad = 'error'; I have a cool feature I wrote which I call "multifields". These are fields which are often used to input a credit card or a serial number, and are actually a bunch of input fields which are “connected” to each other, and treated as one. You can see it in the demo page, and it’s included in the ‘multifield.js’ file.
