Subscription form: How to enter a script-tag (head)

I made an override template called "default.php" for the form in "templates/yootheme/html/com_osmembership/register" and entered the script-tag at the bottom (after the form-tag), but the script doesn't work. All I get is the error I found via Console-Search. The script should load a ref-tag in a write-protected form-field with a specific id. It worked with another form-component but not with membership pro form?

How or where can I add this script-tag in the head of the form (using Joomla 4 and Yootheme Pro as a template)?

Hi Marco

Do you want to load JS file somewhere? Or you want to add to add javascript code to the page?

I need to add the javascript directly on the page with the form. Is it possible to integrate the form also via plugin-code in an atrticle? This way I could try to manage to add the script via the YoothemePro-Setting of the page.

Please take a look at the form (how it should be) on www.meinspenden.club/id - here you can see the working test form: www.meinspenden.club/id2?200test .... if you send link without id-number the field should be invisible: www.meinspenden.club/id2

Meanwhile I also tried the module version of the subscription form, but sadly the script is not showing either: www.meinspenden.club/verein#foerdermitgliedschaft  

Without seeing the script you want to add, it is hard for me to give you the right answer. However, in Joomla, you can use the two methods below to add javascript code to certain page:

$document = \Joomla\CMS\Factory::getDocument();

- To add javascript code, uses addScriptDeclaration method
$document->addScriptDeclaration('var siteUrl = " joomdonation.com ";');
- To add a javascript file, uses addScript method
$document->addScript(' domain.com/js/filename.js ');

In short, you will need to modify code of the subscription form. Maybe add it to components/com_osmembership/view/register/tmpl/default_js.php

(Once the change is done, it should be moved to template override so that the change won't be lost when you update to future releases of the extension)

Thank you for the information. We could implement the script and our system is working now. 

Thank you very much for your help!

Great. Happy to hear that and thanks for the update. Please note that all the changes to the extension should be implemented using override so that it won't be lost when you update to future releases
