Upload interaction

3.2.19 Upload Interaction — allows the candidate to upload a pre-prepared file representing their response.

Also see the attributes shared by every interaction on the overview page. No component-specific attributes beyond the shared base.

Example

Build a spreadsheet simulating 50 cartons of chocolates, 10 chocolates per carton, where one-seventh of the chocolates have nut centres. Upload your spreadsheet file.

<qti-upload-interaction response-identifier="RESPONSE">
  <qti-prompt>
    Build a spreadsheet simulating 50 cartons of chocolates ... Upload your spreadsheet file.
  </qti-prompt>
</qti-upload-interaction>

Renders a native <input type="file">. On selection, the file is read via FileReader.readAsDataURL and the resulting Base64 string becomes the response — worth a callout in your own docs/exports if candidates might upload large files, since the whole file ends up inline in the response variable.
