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; ?

  • 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.

  • I want the final result to be like this:<a href="javascript:;">#link</a>

  • I don't think you can, why do you need javascript:; there anyways?

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);

  • Url::fromUserInput('#') does not work. It does create an "empty" link, but the goal is to get a link with href="#", which is not the result.

The best way I've found is this:

use Drupal\Core\Template\Attribute;

// A value that would inject HTML if you just used string interpolation.
$value_needing_sanitize = '"><h1>BAD</h1><a href="#" class="';

// Optionally add attributes with any HTML sanitized.
$attributes = new Attribute([
  'data-input' => $value_needing_sanitize,
]);

// Create the anchor tag.
$link = <<<HTML
  <a href="#" $attributes>
HTML . $this->t('Click here') . '</a></span>';

// Render array
$render_array = ['#markup' => $link];

If you don't need any attributes set to user input, then you can remove those parts and just create the anchor tag and render array.
