Drupal 7: how do I add the async attribute to an external JS script when using drupal_add_js?
I've tried:
drupal_add_js('http://somesite.com/pages/scripts/0080/8579.js', [
'type' => 'external',
'async' => TRUE
]);
and
drupal_add_js('http://somesite.com/pages/scripts/0080/8579.js', [
'type' => 'external',
'async' => 'async'
]);
With no results.
Would any know how I could achieve this?

You can't achieve this just by specifying the option because drupal_add_js() does not support async attribute.
It is recommended to use defer which is (imho) better because it doesn't block HTML parsing.
async: script fetched asynchronously, then HTML parsing is paused to execute the script, then parsing resumes.defer: script fetched asynchronously and executed only after HTML parsing is done.
However, if you really need the async attribute, you can implement the hook_preprocess_html_tag to alter the theme variables, like so :
function moduleortheme_preprocess_html_tag(&$variables) {
$el = &$variables['element'];
if ($el['#tag'] !== 'script' || empty($el['#attributes']['src'])) {
return;
}
# External scripts to load asynchronously
$async = [
'http://somesite.com/pages/scripts/0080/8579.js',
#...
];
if (in_array($el['#attributes']['src'], $async)) {
$el['#attributes']['async'] = 'async';
}
}
