In this post, I'll show you how to add target attribute to form and submit buttons in Drupal 8.
You have to set the target attribute in the form tag itself:
$form['#attributes']['target'] = '_blank';
To get this functionality to a particular button:
$form['save_and_print'] = array(
'#type' => 'submit',
'#value' => t('Save and Print'),
'#attributes' => array('onclick' => 'this.form.target="_blank";return true;'),
);
To submit the form in same page:
$form['save'] = array(
'#type' => 'submit',
'#value' => t('Save'),
'#attributes' => array('onclick' => 'this.form.target="_self";return true;'),
);
or with jquery:
$('#edit-submit').on('click', function () {
this.form.target = "_self";
return true;
});
To submit in a new tab:
$form['save_and_print'] = array(
'#type' => 'submit',
'#value' => t('Save and Print'),
'#attributes' => array('onclick' => 'this.form.target="_blank";return true;'),
);
or with jquery:
$('#edit-print').on('click', function () {
this.form.target = "_blank";
return true;
});
