动态更改ng模式正则表达式

Question

I want to changing regex pattern by same rules. Example is in Plunker

If is selected type, which have regular expression, model is updated, if value is valid. But if is selected type, which doesn't have regular expression (eg 'string' in my code), model is never updated. Doesn't matter, if function returned null or empty string .

My question is, if exist way, how turn this validation off?

Answer 1

You can return .* when you want to allow any input:

$scope.getValidatorRegex = function () {
      switch ($scope.type) {
          case 'int':
            return /^\d+$/;
          default:
            return /.*/;
      }
};

Answer 2

You need to wrap your fields in a <form> tag to initiate the angulars built-in validation. See FormController

When you do that, the int validation will work, but since numbers can also be strings, your string validation won't work.
