can-define-validate-validatejs

  • npm package badge
  • Star
  • Edit on GitHub

Adds validation methods and observables to a can-define/map/map using validate.js.

defineValidate(Map)

Checks for ValidateJS constraints and attaches useful methods.

var defineValidate = require('can-define-validate-validatejs');
var User = DefineMap.extend({
    name: {
        validate: {
            presence: true
        }
    }
});
// Attach methods to any instance created of `User`
defineValidate(User);
var user = new User();
user.errors();//-> [{name: ['is required']}]

Parameters

  1. Map {Object}:

    The can-define/map/map constructor. Adds errors and [can-define-validate-validatejs.test-set] methods to the prototype of this map.

Usage

Any validation properties must match the structure used by Validate.JS constraints.

For example:

var User = DefineMap.extend({
    name: {
        validate: {
            presence: true
        }
    }
});

Initialize the validators on the Define Map by calling the defineValidate function.

defineValidate(User);

When an instance is created, the instance will have validation properties that can be used in other modules or in templates

In a module:

var user = new User();

var onSubmit = function () {
    if (user.errors()) {
        alert('Cannot continue, please check form for errors');
    }
};

In a template:

<input type="submit" disabled:from="user.errors()"/>
