I am using the following code.

$url = Url::fromUri('javascript:', array('external' => true));
$link = Link::fromTextAndUrl(t("#action"), $url)->toString();

It causes the following error:

InvalidArgumentException: The URI 'javascript' is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 280 of C:\xampp\htdocs\drupal826\core\lib\Drupal\Core\Url.php).

Is this supported in Drupal 8?

I found How to create an EMPTY anchor-only link with l()? but that is for Drupal 7.

  • Did you add the use statements at the top of your code? use Drupal\Core\Url; and use Drupal\Core\Link; ? – No Sssweat Feb 28 '17 at 8:03
  • yes added both use Drupal\Core\Link; use Drupal\Core\Url; – rjD Feb 28 '17 at 9:37
  • If you read the public static function Url::fromUri, there is no such thing as external, I think you're looking for fragment and also javascript: is not a URI. – No Sssweat Feb 28 '17 at 9:45
  • I want the final result to be like this:<a href="javascript:;">#link</a> – rjD Feb 28 '17 at 9:52
  • I don't think you can, why do you need javascript:; there anyways? – No Sssweat Feb 28 '17 at 23:18

So we create url for link which should be empty.

For this we can use ::fromUserInput() and send parameters starting with # or /.

Or create url from route ::fromRoute('<none>') with specific token.

$url = Url::fromUserInput('#');

Way to create link is usual for D8:

$link = Link::fromTextAndUrl($this->t('Some link'), $url);

  • Did you got any errors? – Maxim Ivanov Apr 4 '17 at 11:40
