angular-auto-validate/src/directives/autoValidateFormOptions.js

An automatic validation module for AngularJS which gets rid of excess html in favour of dynamic element modification to notify the user of validation errors

function parseBooleanAttributeValue(val, defaultValue) {
  if ((val === undefined || val === null) && defaultValue !== undefined) {
    return defaultValue;
  } else {
    return val !== 'false';
  }
}

function parseOptions(ctrl, validator, attrs) {
  var opts = ctrl.autoValidateFormOptions = ctrl.autoValidateFormOptions || angular.copy(validator.defaultFormValidationOptions);

  // needed to stop circular ref in json serialisation
  opts.getFormController = function () {
    return ctrl;
  };
  opts.forceValidation = false;
  opts.disabled = !validator.isEnabled() || parseBooleanAttributeValue(attrs.disableDynamicValidation, opts.disabled);
  opts.validateNonVisibleControls = parseBooleanAttributeValue(attrs.validateNonVisibleControls, opts.validateNonVisibleControls);
  opts.validateOnFormSubmit = parseBooleanAttributeValue(attrs.validateOnFormSubmit, opts.validateOnFormSubmit);
  opts.removeExternalValidationErrorsOnSubmit = attrs.removeExternalValidationErrorsOnSubmit === undefined ?
    opts.removeExternalValidationErrorsOnSubmit :
    parseBooleanAttributeValue(attrs.removeExternalValidationErrorsOnSubmit, opts.removeExternalValidationErrorsOnSubmit);

  // the library might be globally disabled but enabled on a particular form so check the
  // disableDynamicValidation attribute is on the form
  if (validator.isEnabled() === false && attrs.disableDynamicValidation === 'false') {
    opts.disabled = false;
  }
