Hiding the Anonymous Discussion Options in the Discussion Re-Design

[JamesSekcienski]

With the enforcement of the Discussion Re-design coming this summer, we have already transitioned to using it to avoid disruptions mid-semester.  We are looking forward to the checkpoints feature that will be coming soon and some of the other new features like being able to view edit history. 

However, we are not ready to support the anonymous discussion feature that is now included since it also hides the identity of the student from the teacher(s) and admins.  We will re-evaluate this in the future as this evolves, but for now we are restricting the ease of access to this feature.  Since we saw other community members express similar concerns about this feature, we wanted to share the code we are currently using to hide and remove the anonymous discussion options from the UI.

The following CSS is used to hide the heading and options from view*:

div#discussion-edit-view
  div#discussion-details-tab
  div.controls
  h4#anonymous_section_header {
  display: none;
}

div#discussion-edit-view
  div#discussion-details-tab
  div.controls
  h4#anonymous_section_header
  + div {
  display: none;
}

The following JavaScript is used to remove the anonymous discussion options and header*:

(() => {
  if (
    /\/courses\/[0-9]+\/discussion_topics\/[0-9]+\/edit/.test(
      window.location.pathname
    ) ||
    /\/courses\/[0-9]+\/discussion_topics\/new/.test(window.location.pathname)
  ) {
    window.addEventListener("load", () => {
      removeAnonymousOptions();
    });
  }

  function removeAnonymousOptions() {
    const anonymousOptionsDiv = document.querySelector(
      "div#discussion-details-tab div.controls h4#anonymous_section_header + div"
    );
    anonymousOptionsDiv?.remove();
    const anonymousOptionsHeader = document.querySelector(
      "div#discussion-details-tab div.controls h4#anonymous_section_header"
    );
    anonymousOptionsHeader?.remove();
  }
})();
