[Bug]: The selection is empty if prototype framework is used

[claudiuj]

Expected Behavior

I know that Prototype is an old framework but it is still used by Magento 1.9.

Current Behavior

When I use cookieconsent with Prototype (the latest version), the selection saved in the cookie is empty (the categories array is empty)

Steps to reproduce

1. Create a config file using GUI interface
2. Create a simple HTML file that includes Prototype framework (I've attached a screenshot of the source

)

3. Run HTML file in browser
4. Set cookie preference
5. Check the cookie value (categories array)

Proposed fix or additional info.

No response

Version

3.0.1

On which browser do you see the issue?

No response

@claudiuj, this is due to prototype modifying the standard Array.from function, see prototypejs/prototype#338.

You can restore the default Array.from as suggested in prototypejs/prototype#362:

<script>
  const iframe = document.body.appendChild(
    document.createElement('iframe')
  );
  const iframeArray = iframe.contentWindow.Array;
  document.body.removeChild(iframe);
  Array.from = iframeArray.from;
</script>

<script type="module" src="cookieconsent-config.js"></script>

This might break other things in your page though.
