How can I load a javascript file into a Drupal 7 page using the Code per Node module?

Question

What is the syntax for including Javascript from a remote location into a Drupal 7 page using the Code per node module?

I have seen this code drupal_add_js('path/to/somescript.js') at Managing JavaScript in Drupal 7 | Drupal.org, but it seems that is not for use on Drupal 7.

What would be the Drupal 7 equivalent?

Answer 1

Code per node module is intented to use to have a custom JS for each node. The JS code must be placed inline, in the node add / edit form. You have this tutorial to see how it works.

If you want to add the same js to a specific content type you can create a module custom where you invoke preprocess node hook:

function YOUR_MODULE_preprocess_node(&$variables) {
  if ($variables['type'] == 'INSERT_CONTENT_TYPE') {
       drupal_add_js('path/to/somescript.js');
  }
}

You can also do this in a custom theme, there are examples in this answer.

If you want see a module with drupal_add_js examples and a nice documenttion, you can see the module js_example , which is a module inside Examples 7.x.

try this just change the link to whatever external library you are trying to import : drupal_add_js('https://cdnjs.cloudflare.com/ajax/libs/ally.js/1.0.1/ally.min.js', array('type' => 'external', 'scope' => 'footer'));

take a look at this : drupal.org/node/905994
