Notes on question type qtp
Set the question type using
<pre id='shellbody' data-qtp='DOM'></pre>
- canvas
- in this case we create a canvas element, call drawFlag with the 2d context, report the bitmap to score.php
- DOM
- in this question type after usr.js has executed pass document.body.innerHTML to score.php
- fetch
- intercept fetch calls, after the promise has been resolved pass document.innerHTML to score.php
- clicky
- trigger a click on the button before checking innerHTML
- if there is a <pre class=test> element...
- complete each action and evaluate the expr each time. The result is a list, usr and ans are compared
<pre class=test>
{expr:[{id:'ride',prop:"disabled"}],
actions:[{},{id:'tall',method:"click"}]}
</pre>
Notes on score.php
Each question creates two iframes one for user input one for model answer.
The containing document cannot see the iframe contents so we use a round-about scoring mechanism:
- Each iframe reports to score.php with the body innerHTML or the canvas content
- score.php responds to the second of the two calls by generating an MQTT message

payload: {"uid":"0.08061187738818432","aid":"1629570082","qid":"Flags_with_Rectangles-1","score":50}
- these messages can be picked up by the parent page, also allows a teacher to monitor a class
