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.

import defineValidate from "can-define-validate-validatejs";
const User = DefineMap.extend( {
  name: {
      validate: {
          presence: true
      }
  }
} );

// Attach methods to any instance created of `User`
defineValidate( User );
const 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:

const 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:

const user = new User();

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

In a template:

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