I am using the following code.

 $form['test'] = array(
        '#type' => 'link',
        '#href' => "javascript:;",
        '#title' => t('Show'),
        '#attributes' => array(
            'onclick' => "show_this();",
            'onsubmit' => 'return false',
        ),
        '#id' => 'myid',
  );

Its output is the following.

<a href="/javascript%3A%3B" onclick="show_this();" onsubmit="return false" id="myid">Show</a>

The onclick event is working properly. I want to disable href.

How can I achieve this?

You don't need the #href to prevent the event.

$form['test'] = [
  '#type' => 'link',
  '#href' => '#',
  '#title' => t('Show'),
  '#attributes' => [
    'onclick' => "alert('hello');return false",
  ],
  '#id' => 'myid',
];

In the above example, I removed the #href and the onsubmit handler and added return false after the alert() function in the onclick handler.
I don't know what you're trying to achieve in your code, but the above example is working for me.


UPDATE: I update the #href in my answer.

  • Thanks, @ismail-cherri, but i got error : Notice: Undefined index: #href in drupal_pre_render_link() – helpdoc Dec 21 '18 at 8:33
  • I updated the answer to include a # for href – Ismail Cherri Dec 21 '18 at 8:38
