Using with AngularJS

After instalation the library will be available through $window service.

It can be injected as follow:

'use strict';

angular.module('app').factory('Validator', [
  '$window',
  function ($window) {
    return {
      create: function () {
        return $window.Validator;
      }
    }
  }
]);

angular.module('app').controller('ModelController', [
  'Validator', '$scope',
  function(
    Validator, $scope
  ) {
    var validator = Validator.create();

    //define rules
    validator.begin()
      .addField('area').validate('isNotEmpty').validate('isSmallerThen', 20).validate('isInteger')
      .addField('price').validate('isNotEmpty').validate('isSmallerThen', 20).validate('isInteger')
      .addField('description').validate('isNotEmpty').validate('isSmallerThen', 20);

    $scope.update = function() {
      var valid = validator.isValid($scope.model);
      console.log(validator.getErrorsList());
    };
  }
]);
