Retrive $message variables in javascript file

Question

I am using Drupal 7.

In the template file page.tpl.php there is a variable called $message which prints the messages like error, warning etc.

I want to access this variable in a JavaScript file. How can I do so?

Answer 1

In your page.tpl.php file:

$my_settings = array(
  'message' => $message,
);

drupal_add_js(array('my_settings' => $my_settings), 'setting');

Then in your JavaScript file you can access $message variable like this:

var message = Drupal.settings.my_settings.message;
