First of all, sorry for the really confusing title, but I have no idea how to make it more reader friendly. On my website, there are three languages: English, Finnish and Swedish. The user can change between these languages from the default Drupal language switcher. Now the key part of the website comes from an API that I think is in JS. That JS element has its own language changing parameter.

src="//www.websiteofapi.com/alpportal/oa_head.js?proj=api-of-our-company&key=api-key-goes-here&lang=sv&leaflet_gshim=1">

So in order to change the language of the JS element I would need to change that "lang=" part to what language I want. I have that script with the address to the API in my page.html.twig file to make the API call to work all across the site.

Is there a way to change the lang=sv to lang=en and lang=fi when the user changes the language through Druapl language switcher?

From the companys API support they said:

you have different pages for different languages: website.fi/drupal/ (englisch) website.fi/drupal/sv website.fi/drupal/fi This means that you should have a different script tag for each of these paths. I guess Drupal allows that with help of a language variable that is accessible in your page template. (But I really know little about Drupal, so that's just a guess)

I am sorry for a long and confusing post, but it is really crucial to get this to work and I am losing my mind. PS! I am really new to Drupal.

Something like this is what you're looking for I think.

theme_js_alter($js) {
  $language = \Drupal::languageManager()->getCurrentLanguage()->getId();
  foreach ($js as $key => $value) {
    if (strpos($value['data'], 'www.websiteofapi.com/alpportal/oa_head.js') !== 0) {
      $value['data'] = "//www.websiteofapi.com/alpportal/oa_head.js?proj=api-of-our-company&key=api-key-goes-here&lang=$language&leaflet_gshim=1"
    }
  }
}

  • Thanks! But where should I put this piece of code? – Hert Niks May 5 '17 at 10:12
