Drupal – Run AJAX command after success of another JS command.

Comment

With ajax_command_invoke, I was getting error: Uncaught TypeError: Cannot read property ‘apply’ of undefined — ajax.js

Terrible!

After banging my head for like 4 hours with ajax_command_invoke, I am finally able to do it. Here is an example code.

function drupal_custom_ajax_test_ajax_call() {
  drupal_set_message('AJAX call received');
  $commands = array();

  $commands[] = array('command' => 'myJSFunction'); 
  $commands[] = ajax_command_after('#main-content', theme('status_messages')); 
  $page = array(
    '#type' => 'ajax',
    '#commands' => $commands,
  );
  ajax_deliver($page);
}

function drupal_custom_ajax_test_ajax_call() {

drupal_set_message('AJAX call received');

$commands = array();

$commands[] = array('command' => 'myJSFunction');

$commands[] = ajax_command_after('#main-content', theme('status_messages'));

$page = array(

'#type' => 'ajax',

'#commands' => $commands,

);

ajax_deliver($page);

}

Here is the full code.
