在Drupal 7中为登录提交按钮添加“onclick”属性

Question

I have a drupal proyect inside another page as an iframe and I want to add an attribute to the login submit button that redirect the top url to an custom url like this:

top.location.href = 'somepage.html';

I'm trying this:

  function hook_form_alter(&$form, &$form_state, $form_id){
    if($form_id == 'user_login_block'){
      $form['actions']['submit']['#attributes'] = array('onclick' => "top.location.href = 'somepage.html';");
    }
  }

I'm sure that the $form_id is user_login_form, but nothing happened.

You need to change the line from

$form['actions']['submit']['#attributes'] = array('onclick' => "top.location.href = 'somepage.html';");

to

$form['actions']['submit']['#attributes'] = array('onclick' => "javascript: top.location.href = 'somepage.html';");
